We are already have many things planned for safety measures. The cart will not only be moving the robot but the operator will also be riding on it. We plan to have a pressure plate where the operator stands and if there is mot more than say 75 pounds on it, the cart wont start. We will also have a main kill switch for the drive lights and horn to help ensure it is safe. The only other thing i can think of off the top of my head is that we will have the ability to disengage the drive motors from the wheels so we can move it manually if needed.

As for the motors, we have the machining capability to make the gearbox and I don't see the added weight being an issue so I think we will be planning on working with the cims still. Also the cart is going to be weighing upwards of 150lbs without robot or operator so a couple of window motors would not cut it. We would need at least 6 if not 8 just to make it move.
