hi fellow Aussie?
I have scrapped the parts from this bot, to make a 4 wheel (4 actuator drive) differential drive robot. The rear wheels are omni-wheels that allow a sliding movement to the side. The only problem so far as i have just assembled it is the actuators are sometimes turning at a constant fast speed and sometimes locking up (stalled) and vibrating it seems to occur on one set of wheels then later on another set. Then sometimes the robot just stops until the MCU? Or maybe it's just the power is reset.
I am going to check the actuators three wires pow, earth, signal and see if they are crossing and leading to signal distortion. I have some capacitors 10 u faradays i think, parallel to the power and earth.
