Tribot swerve

[Gdeaver]

With the 2014 perimeter change from a fixed dimension to a perimeter specification a tribot is no long such a disadvantage. So we made a tribot swerve. Last meeting the mechanical students put the robot together and last night the programmers got code on the robot. Its crab only now. Need to work on the chassis rotation part. Here's a video.

So what do you think? What are the advantages and disadvantages of tribots? Are we foolish? Anyway I proud of the effort the students put into this. They really worked together well and accomplished this fast.
