Small changes to get the robot working.

These include:
- Temporarily disabling PWM output checking. (We don't have
the cable.)
- Negate the encoder values in sensor_receiver. (They're different
encoders from the ones on the other robots, with different colored
wires, so there's pretty much no hope for consistency.)
