Phase K-3 so far

Per my planned iterations of K-9's designs, I am currently at what I've dubbed K-3. At Phase K-3, the Raspberry Pi and servos are mounted to the chassis and the servos have the sprockets attached to drive the tracks.

















This video shows the servos working properly in a short run. The cable you see is only the power cable which is for the Raspberry Pi and the two servos. A shell script executed remotely over SSH is controlling the servos.

Already, I'm having some difficulties. I can successfully control the servos from the Rpi, but one of the tracks keeps slipping. I believe this is because there is tension in the chassis that is uneven and one of the wheels is not level. This means disassembly, which makes me sad.
