If you turn the robot by hand it also turns easily and it doesn't appear to be a problem with the gearboxes. Each motor is pulling approximately 40-45 amps when in max load and we don't believe that would be normal in this type of drivetrain. Has anybody experienced this before?

What kind of wheels?

What's the wheelbase and trackwidth?

How far did you drop the center wheels?

What's your gear ratio?

Put it up on blocks and tell us how much current it draws.
