Re: Actuated Drive (Slide / H)
Yes thank you for catching that. When we had a stack the omni would slip on the carpet, which is why we switched it out for a traction wheel.
These are my basic calculations:
1.25 inch cylinder
.4 inch in diameter rod inside cylinder
60 psi
(1.25)(pi)= 3.92 square inches
3.92-(.4*pi)=2.67 net square inches
2.67*60=160 lbs
The pivot point was equidistant from where the piston was mounted and the center of the wheel.
