I started building a rover based on a 1/5th scale truck. Since most rovers discussed here are 1/8 or 1/10 trucks/crawlers I am wondering if you can provide any thoughts, ideas or recommendations about bigger rovers?
The rover is a 4WD truck with the motor placed in the middle. I’ll place the Pixhawk in the front and already moved the ESC (originally sitting in front of the motor) behind the motor to reduce interference. I am planning to use the power module for powering the Pixhawk.
I have two specific questions:
- Where to place the power module? I.e., should I use a longer DF13 cable from the back of the rover to connect to the Pixhawk in the front or should I use a longer power cable and pace the power module closer to the Pixhawk? The wheelbase is 57cm.
- Can the high torque 6V steering servo be powered from the Pixhawk or should I use the output of the ESC as a direct input to the servo (does this work at all?) and then only connect the signal and the ground to the Pixhawk (for both the ESC and the servo)?
Thanks a lot in advance!
