Abstract
A vehicle for transporting a payload over a surface that may be irregular and may include stairs. The vehicle has a support for supporting the payload and a ground contacting element movable with respect to a local axis, where the local axis can be moved with respect to some second axis that has a defined relation with respect to the support. The vehicle also has a motorized drive arrangement for permitting controllable motion of the ground contacting element so as to operate in an operating condition that is unstable with respect to tipping in at least a fore-aft plane when the motorized drive arrangement is not powered. The vehicle also has an input device for receiving an indication from an assistant who is not disposed on the vehicle of a direction of desired motion of the vehicle.
