6 Top Areas of 3D Scanning Benefits

3D scanning process has proved to be very beneficial in capturing the exact measurements and shape of any given object. It is a technology that has eased production processes in all fields and more people are now embracing the benefits of this sought of scanning where total accuracy of details on an object is needed. It is a process that has actually reduced manufacturing costs and yet offers higher quality parts in the end. Below are some of the top areas the 3D scanning benefits.

1. Prototype

This process can be applied to prototype phase in different kinds of ways, but the major use is to reduce design cycles needed in the prototyping. When 3D scans are used in designing a part, the accurate data makes it possible to utilize precise measurements of the physical product reducing the process by a huge percentage. The scanning is also combined with prototyping so that physical objects are scaled accurately.

2. Design

It is among the areas that have greatly benefited from 3D scanning. They scans are applied starting with physical object and then using this to create a CAD model. Mating parts are also scanned and then incorporated into a given design so the end result is better fitting parts that are consistent. This process is known as reverse engineering or modeling and when utilized, new designs are improved and incorporated for engineering optimization of manufactured part.

3. Production

In production, the scanning is used to capture tooling or parts changes which occur in the production phase. Usually hand tuning is needed in tooling to get the desired finish and look of a given part. When 3D comes into the picture, the optimizations and hand modifications are easy to transfer from tool to tool so all parts manufactured match after the production ends. The scans also help in analyzing and characterizing tool wear during the production; this is very helpful in correcting tool failure or eliminating the same before it is too late. It is actually very possible to recreate optimized part using a 3D scan.

4. Engineering

3D scan data makes it possible for physical objects to be translated into the engineering phase of projects directly. The data offer flexibility in performing FEA, CAE, CFD and other analysis that is necessary in the engineering area on objects manufactured and physically modified. The process offers a simple way of achieving accuracy.

5. Quality control

Using 3D scanning, it has become possible to analyze built condition of parts after manufacturing. This non-contact technology offers a quick way of inspecting overalls size and shape of the parts and detecting issues that could affect performance of the parts. When combined with statistical analysis software, 3D scanning helps maintain and predict the quality of parts in the manufacturing phase.

6. Distribution

It might sound unrealistic, but 3D scanning comes handy in vision systems used in distribution and shipping centers to sort and track packages. The scanning certifies the integrity of products before and after shipping. It is also used to increase packing density and creating support structures and casing.

Lidar scanning systems are some of the systems used in 3D scans to create offer precise digital copies of props, cars, aircraft and even buildings. There is just so much that can be enjoyed using the system

Getting The Perfect Drone For Your Child

Drones make very popular gifts for children and with so many models available for kids, you will find one that your child will love flying. Drones are generally safe for children and you therefore have nothing to worry about. You can actually improve your family time when you get a drone for your kids complete with a camera to capture those moments in the park or around the house or garden.

The good thing about kids is that they are fast learners and it will take a short moment for them to learn how to safely control the drones. It is however still important that you supervise the kids as they enjoy the flying. When you are out looking for the best drones for kids, you will realize that quality increases with price. But there are so many sturdy and cheap drones you can get for your kids. With the right selection, you will be able to purchase a drone that is easy to fly, easy to maintain and one that is durable for that matter.

Consider the minimum flying age

The truth is that drones are not suitable for kids of any given age. Drone manufacturers do give age recommendations when it comes to the mini drones with eight years being the cut for most. You can however also use child maturity to determine what age is perfect for them to own and fly a drone. Whereas age of 10 may look suitable enough, children who are familiar with robotics and such may be able to fly the drones at younger ages. The age should also guide to the drone features that are relevant. For instance, kids over age of 12 will most likely find action camera drones more appealing than those without.

Check speed and size

These are the two elements that play a role in drone accidents. When choosing drones for kids, it is safer that you go for the model made of ABS plastic that is lightweight and durable. This kind of a drone eliminates the damage that could be caused by a much heavier or larger drone, especially when a child is just learning to fly. Small toy drones are basically harmless. Lower yaw rate are also best for kids. Propeller rotating speeds should be selected accordingly to minimize dangers when children are learning to fly. Slow flying drones are safer for kids, but you can always upgrade the size and speed according to the age and skill achieved.

Think about flying environment

You can either get an indoor or an outdoor drone for your child or one that can be flown in both environments. Indoor drones have stable hovers and very responsive commands whereas outdoor drones should at least be wind resistant and feature motor power to keep hover stable. Before buying, ensure that you have enough space to fly it, whether indoors or outdoors. The last thing you want is to have your kids fly the drones in your neighbor’s space which can be privacy invasion.

Drones for kids can keep them busy and excited as long as you choose a safe and secure model. Find out all about the drone before buying so you are sure it is the best for the child.

Advantages of Renting a Drone Versus Buying One

We’re living in a technological boom where every day we’re learning about a new development. Sometimes you encounter a new technology which is more sophisticated and helps you get your work done faster and/or more efficiently. Technology is becoming more so as it is shown in the tech savvy fiction films where the machines have their own brains. Drones are a modern marvel that have impressed not only the military, but have also captured the imagination of the common people too.

There are many people who would like to buy a drone for themselves but these aerial vehicles come at a premium price. This is why you have to weigh various pros and cons before you get to the stage of buying a drone. You may like to have a reception party and capture those precious moments at angles and heights that look amazing. If you have money to spend then you could buy a drone for your personal usage. However, like most people, if your spending budget is low then it is better to rent a drone instead.

There are various companies in the market that offer drone rentals. When it comes to deciding upon buying or renting the drone, you must consider the pros and cons of both.

Usage

Drones are anticipated to have a wide variety of uses in the future but for now the use of drones is mostly used for photography, while few are using them for surveillance, inspections and survey and mapping purposes. So, if you are not a professional photographer who needs to use a drone frequently, you probably don’t need to buy it. Simply renting the drone would be an ideal fit for you as it would allow you to use the drone when you have a need for it and then return it back when it has served its purpose.

Flying the Drone

Flying the drone is a major issue when deciding whether to buy or rent the drone. If you decide to buy the drone then you will have to learn about how to fly it too or it will not serve its purpose. However, renting the drone would spare you from having to learn anything about drone flying. The companies who rent these aerial vehicles will provide a pilot for you that will take over the flying duties. You would just have to tell the pilot what to do and he would deal with the rest.

Licensing Issues

Drones are aerial vehicles and thus require proper licensing before they can be used or flown in the air. Obtaining a license for a drone can be a very time consuming process. The companies renting the drone however have the required licenses and necessary paperwork for their equipment. So, you don’t have to worry about the licensing one bit. You just pay the rent of the drone and can then use it freely.

Cost

The cost of the drone is a major factor to consider when buying it. If you do not want to indulge in drone racing or other drone sports then there is no point in buying this equipment as it will just sit in one corner of the house. Drone rentals on the other hand are a great option for all purposes. If you want to learn about flying a drone or just want to have a little fun with it then a rented drone could accomplish this without requiring you to spend big bucks. Thereafter if you feel that it is worth the purchase then you can buy the drone of your choice.

Purposes for Renting Drones

Drones can be rented for various purposes such as:

· If you are hiking and you want your photos and videos to be made from far then drones can be of help. Also if you want to take pictures of the high mountains and rugged terrains or just have a look at what is on the other end of a high peak, then drones are the only option you have.

· If you are planning on selling your house or property you will need to send good photos of your property to the contractor. With the help of a drone you can take endless pictures of the roof, the chimney, or the windows from any angle without the need for a ladder.

· Drones can even be used to keep an eye on your farm by giving you the bird’s eye view of your land

· Drones can be rented to go for vacation where you can make aerial view videos of your own or you could just use the drone for the purpose of sightseeing.

· Drones can be used for sports photography as well.

Taking Care of Rented Drones

When you rent a drone, you must take care of the following things:

· The date you have fixed for your event or vacation is not a feasible one for the renting company so you must keep your dates and time flexible as this will ensure that you have photographs done the way you want them to be. Also, it is better to get the photography done in the mornings and evenings as this is the time when the sun is best for photography.

· You must know what kinds of shots you want. You should have a look at the similar projects online and make sure that you tell the photographer about the same.

· While taking photographs with a drone you must not forget to first make sure that the place is safe for flying with drone. You must not have trees and buildings as obstacles and neither should you fly them over people. Use common sense to make sure everybody on the ground is safe.

· You must be aware that the drones are of different qualities and that is going to affect the quality of your videos and photos. The DJI Phantoms are the cheapest, most available and most used drones, but for high end picture quality you will need the professional model or a high quality camera and that is going to cost you more.

· Also, it is important that you get the enhancements and corrections done in the photographs, because raw pictures and videos usually need editing.

Tips on Making Distributed Agile Teams Successful

Tips on Making Distributed Agile Successful

Purists and Scrum hipsters will argue that dispersed teams are a taboo in Agile communities of practice. However, in reality there are many instances where an organization has to outsource due to lack of local skill set or other reasons. Being prepared for what to expect and how to approach and prepare for the facilitation of distributed teams can go a long way in ensuring the success of the Agile initiative.

1. Decide on how to distribute

  • Teams work differently in their remote locations, but the whole team officially syncs up at least once a day, but also ad-hoc as situations call for it;
  • ach team in each location has all the necessary skills to execute on the committed sprint backlog;
  • Individuals in different cities must be encouraged to work as one team as opposed to one team in country A and another in country B;

2. Create stickiness or coherence

  • We want teams that will stick together which requires a clear vision;
  • We therefore acknowledge that cultures in our team differ – we should encourage collaboration and relationship nurturing early on in the project for sub-cultures to form;
  • Work actively to strengthen tactical as well as team structures;
  • Build trust through early communication of progress

3. You’re going to have to change how you communicate

  • In the Cinderella Project (a perfect project) a team would come together from their disparate locations to meet, socialize and form cohesion;
  • We encourage teams to stay together for at least an iteration;
  • Learn the lay of the land
  • Become familiar with the ‘flavour of Agile’ being used (e.g. all teams estimate, collaborate, execute and communicate differently – get to know these traits – it’s going to make or break your Agile initiative!)
  • Organize quarterly visits for either the whole team or have people cross pollinate through travelling between locations
  • Invest in the concept of having team ambassadors, people that ensure good working relationships
  • A Wiki culture, or information sharing philosophy is going to be very important, more so than with co-located teams
  • You are going to need more meat on that product backlog to physical counter the absence of key people
  • Horizontal communication must be encouraged and drive
  • Distance isn’t such a problem, time zones are!

When transitioning to a distributed team, err on the side of over-communicating.

4. Additions you’d need to accommodate in the framework you are using:

  • Meetings will require slack time, people are going to catch up (and rightfully so) whether you like it or not;
  • Share news as it happens about the project, good and bad
  • Honour basic meeting etiquette:
  • One conversation at a time
  • Everyone must know who is speaking
  • Keep to the time-boxes
  • Facilitator to set up technology, conference bridge etc. in advance of meeting, and test the connections
  • Ensures everyone has the right dial-in information

5. Technology

  • You’ll have to ensure your technology supports your dispersed nature
  • Use Agile Lifecycle Management tools like Jira, VersionOne etc
  • Use proper high quality video and voice tools to video-conference successfully and to bridge the distance gap
  • Online whiteboards for design sessions will aid collaboration
  • An online Retrospective tool that will ensure the opportunity to improve isn’t lost

8 Tips for Buying Your Drone

Businesses and consumers alike are finding new ways to use drone every day. From real estate to event photography to sports, drones are being used for a number of purposes. On top of that, people are finding drones to be a great past time activity too. This is the reason why there has been a spike in the demand of the drones and people all over the world are looking to buy one. However, buying a drone isn’t a piece of cake. There are a number of aspects that you need to keep in mind before you go into the market to buy one. The following are some tips that are going to help you in buying a drone that is fit for your needs. The following areas should be examined prior to purchasing a drone.

Purpose of Use

The first tip for buying a drone is to identify the purpose for which you want this vehicle. For instance, if you are looking to get this device for purely recreational purposes then even a small and cheap quadcopter would be enough. However, if you want to buy the drone for professional aerial photography and videography then you will have to go for a more advanced model that is capable of capturing photos at different angles. For cargo carrying requirements, you will require a drone that is capable of lifting heavy loads and carrying them over long distance. If you plan on buying the drone for inspection purposes then it would be best for you to opt for a drone that can function in unfavorable conditions. Drones used for wildlife photography are usually quite expensive and should only be bought if you are a wildlife photographer who wants to capture the wild animals in their natural habitat without risking yourself.

Machinery

Another of the aspect that needs to be considered when it comes to buying drones is that of its machinery. There are various types of drones available in the market but they have their own respective mechanisms. You have to understand that not all drones have the machinery available to perform the functions that you want them to do. For instance, if you want to get the drone simply for the fun then a quadcopter with simple machinery would be just fine. However, if you plan on using the drone for a commercial purpose then the quadcopter would not be enough. You will then have to go for a drone whose machinery is capable enough to complete the task be it photography or package delivery.

Design

Another tip that might come in handy when you are buying a drone is to have a close look at its design. Generally all the UAVs have the same basic idea; they fly without the need of an on-board human pilot. However, they differ on the basis of their design. For instance, the quadcopter has four motors to propel it and look almost like a helicopter while the military grade drones are jet fueled and look more or less the same as usual airplanes. So, unless you are in the military and are in need of a stealth drone, it would be best for you to go for a drone that has a simple design.

Camera and Gimbal Supports

Drones are mostly being used for the purpose of photography and videography. If you want to use yours for the same purpose then you will have to find one that has a camera installed on it. However, an ordinary camera won’t do the job. You would have to make sure that the camera mounted on the drone you are buying is a good one that can take high quality pictures with ease. Another tip to keep in mind is to buy drone that has a gimbal support. The gimbal support is going to keep the camera stable during the drone’s flight, allowing it to take better photos and videos.

Battery Time

Battery timing is of great importance too when it comes to buying UAVs. Generally, a quadcopter or drone will fly for around 5 to 15 minutes at a stretch. With a bigger battery, the drone can stay airborne for more than an hour. So, it is best that you go for a drone that has a powerful battery especially if you want to use it for aerial photography or inspection purposes. Make sure that the battery of the drone is rechargeable and can be quickly powered up.

Range

The range of most of the drones is not more than 50 meters. This is generally a suitable distance for taking aerial shots. However, there are advanced drones available too that have a much higher range. If you want the drone for wildlife photography, then it is best that you go for one that can provide you with a range close to 100 meters or more.

Spare Parts

Always ask the dealer to provide you with spare parts for your drone. Most of the drones available in the market come with spare rotors as these parts of the drone are fragile and can breakdown if consistently used.

Cost

The price of the drones is dependent on their type. If you want to buy the most basic model then you won’t have to spend a great deal of money on them. Still, it would be a considerable investment as these aerial vehicles don’t come cheap. You can get the drone for a lower price if you look for them on the internet. There are many websites that provide discounts on the sale of quadcopters.

In closing, there are a number of aspects that you need to keep in mind before you go into the market to buy drone. If you take these considerations in mind you will get the most out of your investment.

Cloud Computing!

Cloud computing has revolutionized the way technology is used to share information and resources to achieve coherence, relevance and economy of scale. These three factors are hugely important today when individuals and businesses require being in the forefront of their activities and achieving profits and revenues while reigning in expenditure.

This kind of computing is the method or model of internet-based computing that provides on demand, processing capabilities as well as data to computers and other devices on a network through a shared pool of resources such as applications and services, networks, servers and storage devices, which can be requested and used with minimal effort. Cloud computing enables businesses and users with capabilities to store and process vital data in third-party data centers.

In simple terms, cloud computing means the storing and accessing of information and applications over the internet instead of leaving them on local hard drives or in-house servers. The information accessed is not ‘physically close’ and the metaphor ‘cloud’ relates back to the days of flowcharts, graphs and presentations where the server infrastructure was depicted as a ‘puffy, white cumulus cloud’ that stores and doles out information.

Cloud computing or ‘the cloud’ as it is commonly known enables a ‘pay as you go model’. The availability of low-cost computers and devices, high-capacity networks and storage devices as well as complementing factors like service-oriented architecture, adoption of hardware visualization and utility computing have contributed to the success of cloud computing in a very big way.

Cloud Computing Architecture

The five specific factors that define cloud computing are:

• Broad network access
• On-demand self service
• Resource pooling
• Measured service
• Rapid elasticity or expansion

Broadly, that sums the essence of this kind of computing. However, there are several loosely coupled components and sub-components that are essential to make computing work. These are divided into two sections – the front end and the back end which connect to each other via the Internet.

The Front End is the physically visible interfaces that clients encounter when using their web-enabled devices. Not all computing systems use the same interfaces.

The Back End comprises all the resources that deliver cloud computing services. These are essentially virtual machines, data storage facilities, security mechanisms etc. that together provide a deployment model and are responsible for providing the ‘cloud’ part of the computing service.

Benefits

Exponents of computing are quick to praise it citing the many advantages and benefits it provides. Among the many benefits, the prime ones are:

• Enables scale up and scale down of computing needs
• Enables businesses to avoid infrastructure costs
• Allows companies to get applications running quicker and faster
• Improves manageability and adjustability of IT resources to meet fluctuating business demands
• Reduces maintenance

The high demand for cloud computing is further enhanced by the advantages of cheap service costs, high computing power, higher performance and scalability and easier accessibility and availability.
