This robot has been designed for the VEX-IQ robotics kit. It can be made from parts from a single VEX-IQ Starter Kit (http://www.vexrobotics.com/vexiq/products/starter-kit-with-sensors.html)
This design is quick and very simple, it should take no more than 10 minutes depending on your students. It is not the most robust design, but is intended to be built quickly by students, allowing them to spend more time with the programming aspect of STEM education. There are plenty of connection points to add sensors and make the robot more sturdy, and I highly encourage you to get your students to come up with their own modifications.
For a faster build, have one student do the left motor, one do the right motor and one do the castor. Then bring them all together at the end.
If you do use this in class, please let me know, I love to see how far and wide my designs go 🙂

Hi Hasan,
I use the E and F buttons on the controller to move the robot. If you want to use the joysticks, I think you'll have to try different ports on the VEX-IQ brain.
Thanks a lot Dr. Damien, i built the model but i couldn't get it move, while i see values of controller changes on LCD but no motion in the motors
Thanks Whitepass for your comments. I was seriously tossing up adding those pieces in, but in the end left them out to focus on the minimalistic nature of the design. Those parts would certainly make it more robust, although I would also add in a bunch of spacers on the wheel axle to stop the wheel rubbing on the outside beam. I'm really hoping students use it as a starting platform, just to get things up and running and then improving on the design. There are plenty of places to make it better! 🙂
If you add 2 2×8 Beams and 4 2x pitch Standoffs you get a much better robot that the wheels can not come off.
