So after long debate, we have decided to release a video of one of the drive trains that has been built by one of the students. The robot hasn't been programmed as of yet, except to drive in a straight line, which is why you will see students turning it. This is the drive train for just one of our robots (just imagine what we aren't showing you).

Have fun and good luck this year.
