This is very much so the goal! We're looking to use this robot, once fully built and tested, for promotional purposes on Columbia University's campus and during competitions to excite crowds and promote interest in the maker community at Columbia.

It's actually a triangle! Spinning in place is our easiest way of approaching turning right now.

Thank you!

We will definitely need to reinforce how those rails are braced together. The frontmost rail is support entirely by two swerve modules and the 1/4" ABS bellypan, but since we also expect it to take the brunt of impacts from terrain, we'll be adding additional gussets to strengthen that structure.
