Thanks, Frizzen!
Here are some specs on the parts too:
- A normal 4ch RC transmitter and receiver (for once no embedded PC :-) )
- 1 x 3S battery ~2000mAh
- 2 x
Sabertooth 2x5 R/C
- 4 x
JGA25-370 12V 24RPM
-
1 x L12-S Actuator with Limit Switches - 30mm - 100:1 - 12 volts
- 2 x
L12-S Actuator with Limit Switches - 50mm - 100:1 - 12 volts
The steering is controlled by wiring the motors such that both the front and the rear part move as tanks, but in opposite directions. I only use one controller for both the drive and steering. The other controller controls the boom and bucket.
The wiring for the drive motors:
- Channel 1: Front left motor + rear right motor
- Channel 2: Front right motor + rear left motor
The first motor controller works in mixed mode. The other in normal mode.
