Hi all.
I have a skid steer rover currently running RPI 3b+ using 4g telemetry and video over UDP.
I’m having issues with configuring the parameters correctly. I’m using a pololu trex Jr dual brushless motor controller in conventional rc input mode. The 2 channels are connected to outputs 1 and 3 and have the ESC settings set to brushless bipolar. Servo1 is set to throttle left and servo 3 is set to throttle right. I can’t seem to get the motors to operate.
Could anyone with a skid steer rover please share there parameter setup to point me in the right direction for the necessary configuration to get the motors online?
Thanks so much! That worked! I was convinced brushless bi-polar was the option to choose but I was wrong.
I now have one small other problem. I can’t seem to achieve reverse. The motors can reverse direction… for example… they move in opposite directions when performing a spot turn… but I can’t reverse the rover using the on screen joystick. Initially the rover would just start driving… that was until I turned “auto joystick centre” off. That fixed the auto driving problem as I could zero the joystick. Unfortunately I actually want the joystick to centre so I can choose forward AND reverse.
When you are saying “onscreen joystick” are you refering to the QGroundcontrol onscreen joystick?
I do not use Qgroundcontrol that much, but I remember a check box in the joystick setup screen, to set zero throttle at the bottom or in the middle. I do not know, if this also affects the onscreen joystick.
