Abstract
An auxiliary pusher device for pushing a wheeled cart along a surface, the cart equipped with a handle for pushing the cart. The device includes an adjustable length chassis, a grip element connected to the chassis for engaging and gripping the handle of the cart, a drive wheel connected to the chassis, and a motor engaged with the drive wheel. The motor is operative to apply a drive force to the drive wheel, thereby applying a corresponding drive force to the chassis and via the grip element to the cart. The drive force includes a force component substantially parallel to the surface causing the cart to move on the surface. A hand grip is connected to the chassis allowing a user of the device to guide the direction of the cart. A parking station for the device and a method for use of the device is also discussed.
