The robot doesn't weigh all that much (we're at least 50lbs under limit)
And the motors seem completely unresponsive for the first few degrees of input from the joystick.
To add insult to injury...it's overheating.
There's a familiar smell of burning after a few minutes of run time.
Did I mention both motors had their brushes pop out?

First, if you can't get any torque on the ramp, I would think your gear ratio is too low so the motor is running very low on the power curve, but then... You mention that both motors had their brushes popped out and I begin to wonder if the brush assy isn't damaged/misaligned causing some electrical problem. The most worrisome is the smell. I have always held this axiom..."If it smells burned, it is. If it is burned, replace it. If you don't replace it, it will fail when you need it and then thumb it's nose at you by sending smoke and flame in your direction."
BTW, what was your design speed and are you able to achieve that speed on a flat surface?
