TrakBot

Last week I picked up a Tamiya tracked vehicle cassis from a hobby store to use as a mobile platform.  http://www.superdroidrobots.com/shop/item.asp?itemid=484

Sunday and Monday I put it together and canibalized my old Hookbot for the H-Bridge, gearboxes and PIC.  I used the Tamyia dual gearbox drive rather than the one that came with the chassis because any good robot can turn, not just go forward and reverse; hey maybe I’ll use the single motor for a turret!  Anyway the brains are a PIC 16F872 and the H-bridge is a SN754410.  The drive motors are power by three AA batteries for ~4.5volts and has a bit of acceleration and power, I am quite impressed.  Right now the H-bridge gets a little warm when the motors are strained.  I am going to have to do some tests and see how hot it gets on carpet running for a few minutes.
