Re: [CAD_CAM_EDM_DRO] Re: Problems in Timing Belt drive system in 6WD robot

Great hearing from you Bill !!!
Just a little 'OT' to stir your juices again.. ha!

I've had that very same issue with robot stability building and
programming them. Where one suggestion to me was modifying stepping
code during the turn for the inner wheel not moving so much, my solution
was more reliable for long term stability by installing a mechanical
Limited-Slip system.
