Re: Baxter Bomb Squad 2014 ~ Nighthawk

I had the chance this past weekend to see their swerve pods in-person, including the experimental one with the 3D printed blue plate. I'd like to thank the members of Team 16 for answering all my questions with patience.

In the picture posted, the piston is located under the black mounting plate, and adjacent to the blue one (its the grey cylindrical object in the cad). From what they told me, it was designed to test out and eliminate the twitching that the modules may have when trying to drive in a straight line. Because the control system tries to compensate the drift, and then over-corrects the action, the piston would lock in to the appropriate groove when needed and make sure the robot drives in a straight line.

They did mention that they would have to do some more testing with the current design since the motor was able to overcome the piston lock fairly easily.
