I’ve assembled the Donkey Car (using the Jetson Nano instead of RPi). I’ve also replaced the NiMH battery with a LiPo. I performed the calibration procedure, calibrating both the steering and the throttle, which had worked initially with the ESC beeping in response to the 370 value entered into the calibration line. I added the maximum, zero, and reverse throttle values to the myconfig.py, and had test driven the Donkey Car using the web browser controller. I originally had trouble with the camera not being recognized by the Nano, but was able to resolve this with further changes to the myconfig.py file. The test drive worked for a few minutes, but then stopped responding to any throttle value, but steering still worked. The ESC red LED was blinking.
What I’ve tried:
-I noticed that the ESC had the jumper set to NiMH instead of LiPo, and I switched the jumper to LiPo.
-I changed the ESC control wires on the I2C board from Channel 0 to the Servo Steering Channel 1 to see if they respond to the signal from Channel 1
-I reconnected the ESC to the RC receiver and tried the throttle trigger, and the ESC/Motors responded to the trigger with both forward and reverse on the trigger.
-Run donkey calibration again on the throttle channel to test calibration again. This time, setting PWM value to 370 did not produce a beep from the ESC, and I then tried several different integer values from 0 to 1500, but again no response from the motor.
I’m afraid I am out of ideas regarding how to further troubleshoot this issue. Any help would be appreciated.
