When building a mobile robot, selecting the drive motors is one of the most important decisions you will make. It's a perfect example of an ideal world meeting the real one. Here are some of the basic physics and the rules of thumb for proper motor selection.
Living near the ocean opens up an opportunity to view and take video of underwater sea life – especially if you have your own ROV that is waterproof. Follow this short series to build your own underwater rover with easily acquired parts that can be assembled with basic tools.
Pilots of regular aircraft have a panel of instruments that indicate important parameters such as the aircraft altitude, air speed, attitude, and engine system status. In this episode, we are going to add a telemetry kit to the ELEV-8 v3 to get real time aircraft data sent back to our tablet in the field.
Underwater Remotely Operated Vehicles (UROVs) — the little brothers to the massive commercial underwater vehicles used to inspect hulls, ship wrecks, and pipe lines — are where quadcopters were five years ago. However, with time, prices will drop, parts will become more plentiful, and the Web will be full of videos of underwater sea life and perhaps even battling UROVs.
The Combat Zone
After a tough match at the Franklin Institute combat robot event, the windings (or coils) had come loose and had been damaged and in some places cut. Get some tips on how to harden and make effective repairs on these kinds of parts.
In some ways, analog servos are the “unsophisticated brutes” of the robotics world.Thoroughly understanding their strengths and limitations can help you identify which things are better handled in hardware vs. software.
This new series of articles will explore the many methods, materials, and innovative new ideas to bring your robotic creations to life.
Stepper motors have the ability to precisely turn a wheel at a calculated distance and also the ability to brake, which makes them an interesting choice for robot propulsion, but not without some some tradeoffs.
We take for granted all the motors, sensors, high power density batteries, and microcontrollers that are contained within today’s experimental robots. But, back in the day, some of the very best parts came from jukeboxes and pinball machines. Anything with parts that moved usually had something that was useful to robot builders.
