Introduction:

This drivetrain consists of four motors that are driving a total of six wheels with three on each side by chain. Four of the six wheels in this design are 4" Omni wheels from AndyMark and the remaining two are AndyMark high performance wheels. We tested the wedgetop treads and the performance treads separately, as demonstrated by the data below.

This is the most difficult robot of them all to make due to the custom wheels. Owen

This is the completed high performance wheel after 7 extrudes, 2 patterns, 5 rounds, and a chamfer; it took several hours of work and LOTS of constraints. making it the 2nd hardest part made for this robot. Owen

Ramp test - Passed at all weights

Summary:

Whirlwind...
It spins really fast.
Like a furious whirlwind...
Super-duper spin.


It was incredibly good at spinning no matter how much weight we added, making it very maneuverable. This would be a good offensive robot with decent defensive capabilities, as it took a lot of weight to move it. It is also optimal to gear up this drive train for different strategies, as its overall effective performance would carry over to any strategy.
