I am currently working on a project that involves several 3pi robots. Most of them already had a few hours run. As time goes, mechanical problems appear:
Some of them have a mechanical resistance growing on one of the wheels, which makes it harder to spin, or in some cases the wheel is just totally blocked. I unmounted the wheel part to look for some dust or parasite but the wheel itself seems fine, it is the motor part that is indeed blocked, and I have no idea what to do about it. The robots are moving on a dedicated platform ans are therefore not subject to much dirt, falling etc.
Does anyone have experience with this/ knows how to fix such things?
Any help greatly appreciated!
