I’m new to RC robot stuff and really hoping someone can help. I’m making a 4 wheel drive bot out of wood to push dirt. My setup is as follows:
- 4 x 24V 250W wheel chair motors
- 4 x 12V 35AH batteries connected in parallel and series
- 1 x 12V 7.5AH to power the actuators and receiver
- Flysky 6 channel remote
- 2 linear actuators to control dirt pushing attachment, which is basically a snow plow.
- Sabertooth 2x60
- Sabertooth 2x12
- Pollak Solenoid Switch
- 2 x 40 amp fuses
- Battery Switch, Briidea 12V-48V Battery Disconnect Master, https://www.amazon.com/gp/product/B08X1J3Z62/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
My wiring is essentially the same as the schematic shown in this tutorial for the snow plow robot: Tech Thursday #033: How to power a big electric motor – SuperDroid Robots
I’m using 10 AWG wires to go from the batteries to the motor controller. Then I have 14 AWG wires going from the motor controller to the wheel chair motors.
The sabertooth is operating in mixed mode to allow skid steering, so dip switches 1 and 5 are off. When I drive forward and backwards the system runs fine. When I turn right or left, the 2x60 stalls. The error light turns on and the status lights stays on. I haven’t connected the linear actuators to the receiver. I disconnected all switches and tried to run the system straight from the battery, but I received the same error. I’m not sure what is going on… thanks for any help!
