Re: Team 166's robot

When it comes to mechanums, the sideways translation speed compared to the forward speed is set by the angle of the rollers. It looks like they are using the Andymark mechanums (please correct me if I’m wrong here), which I think use 45-degree rollers. This would mean that all else being equal (motor bias and so on) the top sideways speed would equal the back ward and forward speed. This also means that the top speed when translating at 45 degrees to exactly forward or sideways would be 70% of the original top speed. This is the same for omnis; just that one must usually rotate the frame of reference 45 degrees.

The chassis looks amazing and looks like it drives very well. One thing I notice though is that it seems to drift when moving around. Is that an artifact of the movement or the controller?
