Dragging drive wheels

Hi team. I have a toyota 7FB18 model which when driven, you have to give it a small push to move. But when driven normally, its just shaking/dragging. Can't move.

Hi
Sounds like a encoder problem or ONLY working with 2 phases. Usualy if it has danaher traction controller, machine try to work even without a phase.

Check encoder and encoder wiring, check also the current U, V, W with a ampmeter, should have same current in each phase (power Wire to traction motor)

Fact of the week
The word "robotics" was coined by Russian-born American science-fiction writer Isaac Asimov who first used the word in 1942 in his short story 'Runabout'. He characterised robots as helpful servants and as "a better, cleaner race."
