Pivot drive Steering Motor selection
The BaneBots RS540 motors used in 2011 are not available for the 2012 robot. Alternatives are BaneBots RS395 and BaneBots RS550 motors. After analysis, BaneBots RS395 motors with 132:1 reduction were selected, primarily based on their lower contribution to robot mass.
Motor/Gearbox for Barrier crossing
Early prototype testing using DEWBOT VI demonstrated that raised, 8" diameter KitBot wheels are incapable of allowing a pivot drive chassis being driven over the mid-field barrier. An alternative is the use of driven, 8" diameter pneumatic wheels. What motors & gearboxes are needed to drive these wheels? Analysis indicates that FisherPrice motors and Gearbox's will do the job (one should alone, in fact, if the power transmission to the two wheels is managed).
FRC Team 1717's awesome pivots
Team 1640 is generally considered a competent practictioner of pivot (a.k.a swerve, unicorn,...) drive. I was, however, humbled when I saw team 1717's (D'Penguineers) pivot module at St. Louis. More so afterwards when I watched videos of how they move. If we ue Pivot again, we've got a new performance target. My photos from Championships are below.
