Sliding around... spinning around.

The wiring and electronics for the new omniwheel robot are coming together nicely. Having wired this up using 4 individual stepper controllers, one sees the value in commissioning a custom base board for the stepper drivers to plug into. I still have to connect an IMU to the beast, so precision strafing will (hopefully) be obtainable. The sparkfun mecanum video has the more traditional two wheels each side design, but does wobble a bit when strafing.

Apart from the current requirements the new robot is also really heavy, probably heavier than Terry. I'm still working out what battery to use to meet the high current needs of four reasonable steppers on the move.
