We’re currently trying to make a RC Car working with a micro HKPilot.
The GPS module we have is working (even if it’s not really accurate)
The telemetry module is working
However, we are encountering problems with the motors, both the brushless and the servo.
We connected the brushless motor to the pwm signal number 1 coming out from the HKPilot. And we did the same for the steering with the output number 2.
We uploaded a mission with waypoints on the Rover and it has been a real disaster !
The rover was going backward with full speed, it was stopping unexpectedly and was not following any kind of path.
The compass and accelero were calibrated
The cruise speed was set to 0.3m/s and the base throttle was about 20% (we tried a lot of other values also…)
The battery was charged (7.2V 2200mAH)
The waypoints were loaded
Any idea how to solve the problem ? Is there a way to try the motors manually, to adjust the speed and make it go forward ? And same for the steering servo ?
We tried using an oscilloscope, but it was working only for one specific duty cycle and it was going way to fast.
We also tried using the Mission planner motors tests, but it couldn’t detect any motor.
Also how the rover is supposed to get its actual speed ? (From the accelerometer/GPS?)
I will try to post some pictures of the rover and all the connections we did as soon as possible.
Thank you in advance for any help
