Abstract
A shopping cart that avoids collisions during movement comprises a proximity detection system comprising one or more sensors that detect and recognize an object along the path of the shopping cart; a controller that determines from data collected by the one or more sensors whether a collision between the shopping cart and the object is possible; a feedback system that provides one or more of audible, visual, or tactile feedback to a user of the shopping cart when the controller determines that the collision is possible; and a braking system that automatically stops the shopping cart from continued motion when the controller determines that the collision is possible. At least one of the feedback system and the braking system is activated in response to the controller determining that the shopping cart is a predetermined distance from the object.
