Motor Questions

If I were using a single motor, what motor would I use to move around 100lbs? I have plans for a 100lb 4 wheel RC but have no idea how to decide on the motor. The “Internet” says use something like a wheelchair motor. Is there anything on robotshop that is “like” a wheelchair motor? I don’t need it to go fast per se, but need it to have enough power to move the 100lb weight.

The Drive Motor Sizing Tool is exactly what you need. You’re looking at something like the CIM motor plus gear down.
