Abstract: A robot includes a cart sized to receive one or more objects, a moving part coupled to the cart, a handle assembly coupled to the cart, a first sensor coupled to the handle assembly and being configured to sense force applied to the handle assembly, and one or more controllers. Such controllers are configured to: map a magnitude of the force sensed by the first sensor to a speed or to a direction of movement using a pattern of changes in the force that is sensed by the first sensor; and cause the moving part to move the cart according to the speed or to the direction of movement based upon changes in the force sensed by the first sensor.
