RECF STEM Educational Video

Create a video to teach a new team something about the STEM aspects of robotics engineering or construction that you have learned from experience that can help them better prepare for a competition. You should come up with your own idea, but here are some sample ideas from previous years’ Educational Videos:

  • How to calculate loads for robotics mechanisms
  • How to build a specific mechanism such as a drive train, lifting arm
  • How to best use specific robotics components in designing a robot
  • How to use programming with the hardware to accomplish something specific

3129A: Mythbusters - Wheels vs. Treads

user54634

In today's episode of Mythbusters, watch as Adam and Jamie attempt to bust the age-old myth from the VEX forums that wheels are better than tank treads on VEX robots. They will put this myth to the test by using two nearly identical robots (one of which uses wheels and the other uses treads) to see the benefits and downsides of each system. Please note that during the testing in this video, the outside diameter of the sprocket used to drive the tread robot is the same as the outside diameter of the wheels on the other robot. Under ideal circumstances, this should allow both robots to drive...

Making a Winch and Release

Niamh C

We've made a video on how to modify the standard winch unit so that it releases the drum instantly. We used this mechanism on our robot to load and fire an elastic powered catapult. We used AUTODESK Inventor Professional to create all the images and movie files. Narrated by Niamh Conlon Images made by Mitchell Coleman and the 5606 Design Team.

Quick Disconnect Motors and Testing Program

user532219

Over several years of doing the VRC, we have had an issue with motors. The location that the motors were at, made it hard to get in and change the motor out if it started to burn out and fail. To battle this problem the VEX team 3876C has innovated a BATCAVE (Briskness And Torque Checker of Awesome Vex Equipment) to test motors and quick disconnect motors to make the motors easy to test and replace through the season

user820254

Hai Sing Catholic School Robotics are well known for applying Math and Science concepts in building VEX Robots. We were featured in our local news for being able to incorporate robotics into our curriculum. Being able to apply Math and Science concepts in building our VEX robots has given us much confidence needed for us to build a well performing robot and it has also given us confidence with the various skills and knowledge gained. In this video, we portray how Maths and Physics has helped us in building our VEX robots that we have used for Singapore VEX Championship 2013 and Asia...
