You'd have to be crazy to build something called a sextacanum with a bunch of high school students.

There are four ball shifters with 1 CIM an 1 mini CIM powering the drivetrain. Mechanums need to be individually powered to make full use of their strafing abilities.

Wow, Octocanum modules and ball shifters? That's quite a bit of weight! How much weight are you guys ball parking?

The tension design wasn't really cutting it, so we changed to a much better pneumatic version.

Also, Solidworks is showing weight at around 115 without battery and bumpers, although a few things do not have accurate weights.
