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.
We are 7121B Mavericks and we wanted to make a video on cable and power management. During our process of building our robot, we spent a lot of time trying to fix the cables since some of the speed controllers and motors were not working. We wanted to make a video which shows a much more efficient process into the cable and power management.
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.
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.

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!
This is a video of our STEM research presentation on Roger Sperry's split brain study. In this study, the corpus callosum was split and the effects of this procedure was tested with patients. The language capabilities of the brain were discovered from this study and Sperry won the Medicine Nobel Prize in 1981 for his work. Click on this link to learn more: https://youtu.be/oGHG0ycUMRw
The goal of this video is to introduce the use of integrated motor encoders (IMEs) in autonomous programming using RobotC. The benefit of IMEs over time delay programming is that IMEs give exact numerical data which can be reproduced exactly without regard for battery power. Many teams will find that using IMEs greatly improves the accuracy and reliability of their autonomous code!
Once installed, the IME provides much information by utilizing direct feedback from the motor. The speed of the motor can be determined by dividing the change...
Team Bext of the VEX 22283A's Educational Video...
This year's VEX EDR challenge, Starstruck, has a need of using some sort of lift to get stars and cubes to the other side of a fence. Team 22283A belives that controlling lifts is quite hard especially during autonomous, because gears sometimes doesn't have enough torque to make a lift stay at a certain position. Hence, our programmers developed a program template which would allow viewers to copy/paste our code to make an easy autonomous arm control. We hope to help new teams, like ourselves, do well in competitions...
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!
Hello! We are ROBOTECH team and this is our entry to the 2017 REC Foundation STEM Educational Video Online Challenge.
Learning by STEM is fun, you can learn a lot of rules in mechanics during Building the robot, so in this video we will talk about manipulators which we can classify it into three basic categories: Plows, Scoops, and Friction Grabbers.
We found the limitation of using CLAWBOT to learn programming, and we developed this sensor panel to further practice our programming skill with different sensors and complex control structure. And we could also use this sensor panel to test our mechanism before we put them onto our robot!
It's very useful and we hope every team could have one to practice their programming skill!!
We're Phoenix 2250G, a robotics team participating in the VEX Robotics Competition. This our entry for the REC Foundation STEM Educational Video, in which we show how each field of STEM are related to the VEX Robotics Competition. We hope you enjoy this video showcasing the different fields of STEM (science, tech, engineering, and math) altogether with robotics.
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...
This educational video explains gear ratios. The most relevant points of this subject are discussed here, such as partial relations, total relations and vex concepts. You could also see a brief explanation of how you can apply all these concepts. We hope this video can help other participants and the general public to have a better understanding of gear ratios.
Overtightened or skipping chain is a common pitfall in competitive robotics. Due to either pressure on shafts or unnecessary slack, it can cause a myriad of issues including reduced speed and efficency, high current draw, skipping, sensor data loss, shock loading, and bent shafts among other things. Well tesioned chain is a foundation that will set any robot on its way to success.
El objetivo de este video es de explicar los cálculos de Ingeniería Aplicados (STEM) en el Sistema de Transmisión del chasis y brazo del robot asi como es: Velocidad, el par, fuerza, número de motores requeridos, calculo de cuantos motores se requieren para un chasis,todo esto para que el robot de este es optimas condiciones de funcionamiento de poder ser competente.
This project was designed to explore the uses of a planetary gear system. This video explains how a basic planetary gear system works and how it was integrated into a model car; it also displays the creation of actual car mechanisms, with VEX parts.
This video was made by a student who was trying to egineer a motor efficiency tester for himself and his team. He did so by using formulas for efficiency and angular momentum. He ended up finding a reliable way to test the peak performance of motors, and which ones were best.
We are VEX JETS Team #4073B. We are located in Quartz Hill, CA and have a total of 24 team members spread across our three teams, #4073A, B, and G. We utilize Autodesk Inventor 2015 in order to 3D model and assemble the robot virtually as well as accurately prediciting the amount of stress a part can withstand.

In this video, my team and I about the different types of wheels and what they each do. We explain the different aspecs of each wheel depending pn what you want your robot to do. In this video we explain three different types of wheels: Omni direction, Traction, and Mechanical.
In this video, team members discuss the advantages/disadvantages of drive configurations in a holo vs. H-drive review. Our lead programmer also discusses the intricacies of coding these advanced drives and compares their code structure, giving a good deal of instruction in coding these unique drive systems.
Make it happen.
