摘要： According to embodiments of the invention, systems, methods and devices are directed to a shopping cart with safety features which prevent or reduce the risk of injury caused to those using the cart as well as those in the vicinity of the shopping cart. A wheelbase of the shopping cart may have a set of wheels. Each wheel may have an airbag stored therein. The airbag may be deployable from any one of the wheels such the wheel is engulfed, fully or partially, within the inflated airbag. A pressure sensor may be attached to each of the wheels. The pressure sensor may constantly monitor the force being exerted in the wheel in order to identify moments when the traction may be comprised or when the cart may be at risk of toppling over. A speed or velocity sensor is attached to the wheelbase to monitor and detect for excessive speeds. The airbags may be inflatable by one or more compressed air or compressed gas cylinders or vessels.
