REC Foundation STEM Educational Video

In order to help a new team better design and build their robot, create a video to teach them something about STEM concepts applied to robotics. Focus on the science, construction, engineering, and/or math of designing and building robots. You should come up with your own idea, but here are some sample ideas from previous years’ STEM Educational Videos:

  • How to calculate loads for robotics mechanisms.
  • How to build a specific mechanism such as a drive train or lifting arm.
  • How to best use specific robotics components in designing a robot.
  • How to use programming with the hardware to accomplish a specific task.
  • How to use CAD software to design and test your robot before it is built.


Beginner's Guide on Building a Clawbot

Ian Clavio

Are you interested in robotics? Do you want to build a robot? Well, VEX Robotics best suits to beginners.

Every time robotics teams recruits new members, they assign them to build Clawbots with a team. Don't know how to build a Clawbot? Don't worry, Nerd Herd Team 687A from the California Academy of Mathematics and Science (CAMS) will explain everything you need to know on how to build a VEX Robotics Clawbot.

Gears and Gear Ratios


Our team created a video about the application of gear ratios in robotics and how to calculate them. This VEX season, we noticed that although most people know how to use gear ratios they often struggle to explain them mathematically, so we wanted to create this video to help others gain a better understanding of exactly how gears work to change a system's mechanical advantage.

What are Gear Ratios?


5735B REC Foundation STEM Educational Video:

This is our team's entry into the educational video online challenge. For our entry, our team chose to explain the fundamental concepts of gear ratios (one of the most necessary mechanisms in Vex Robotics). We hope you enjoy, and that you are able to learn something from our video, regular viewers and judges alike!

The Engineering Process


Hello!  We are Team 4142 and this is our entry to the 2017 REC Foundation STEM Educational Video Online Challenge. 

This year, our team has decided to present the general concepts of the Engineering Design Process, a process which is rather fundamental to the development of any robot or program.  We hope that viewers will be able to grasp the ideas presented in this film, as well as enjoy the production!

Team 1826A REC Education Video - Understanding...


We wanted to create a video to pass along information to the rest of the VEX community about the VEX EDR Yaw Rate Gyro Sensor, that we learned last year.  For the Nothing but Net competition, we came up with the idea for a turreted design that would be able to automatically aim and shoot from any position on the field.  The key to being able to make a robot that could do this, was for the robot to know exactly where it was on the field at any time. At the very heart of developing that capability was the need for the robot to very accurately know what direction it was facing at...

Geared For Excellence

Control Loops


We, the members of team 1200C, decided to create an introduction to Control Loops, in order to help teams both learn about PID, and how it can be used to create a more accurate autonomous program.
