Default MOW - Motor on wheel crawler

Hi guys,

this project was for a long time on my mind. I always wanted to build a crawler with a wheel hub motor. Finally I found electric components which seem to suit. I have already tested servo driven wheels, which was quite problematic. Now I m going for brushless gimbal motors.

So let's start with the setup. I decided to use brushless gimbal motors as they provide torque and direct drive at a small size. I was searching a long time for a ESC which can control these motors. You can't use normal brushless ESCs. I bought 2 of these special gimbal ESCs, 1 per axle.

All of the parts for the axles are 3d printed. The axle is a simple aluminum tube. At the moment I'm testing the design, so it will take a few days until I m finished. However, I think it is time to share with you my design and maybe get some useful feedback.

Here you can see the state of play: https://youtu.be/oREFFpP1Qxo
