A cart robot analyzing a hand motion of a user is disclosed. The cart robot comprises a code input interface obtaining a product identification code, a sensor detecting a hand motion of a user, a weight measuring device measuring a weight of one or more products contained in a product loading space, and a controller. When there is no change in weight of the loaded products, the cart robot updates a shopping list with respect to the products loaded in the product loading space in real time by analyzing the hand motion of the user. Therefore, the convenience of the user is enhanced.

A robotic cart platform with a navigation and movement system that integrates into a conventional utility cart to provide both manual and autonomous modes of operation. The platform includes a drive unit with drive wheels replacing the front wheels of the cart. The drive unit has motors, encoders, a processor and a microcontroller. The system has a work environment mapping sensor and a cabled array of proximity and weight sensors, lights, control panel, battery and on/off, GO and emergency stop buttons secured throughout the cart. The encoders obtain drive shaft rotation data that the microcontroller periodically sends to the processor. When in autonomous mode, the system provides navigation, movement and location tracking with or without wireless connection to a server. Stored destinations are set using its location tracking to autonomously navigate the cart. When in manual mode, battery power is off, and back-up power is supplied to the encoders and microcontroller, which continue to obtain shaft rotation data. When in autonomous mode, the shaft rotation data obtained during manual mode is used to determine the present cart location.

A weight system includes a cart comprising a plurality of wheels and a frame on the plurality of wheels. The frame has a plurality of rails, and a basket is suspended from the plurality of rails of the frame. A weight sensor is coupled at one end to the suspended basket and attached at another end to one of the plurality of rails of the frame from which the basket is suspended. The weight sensor is adapted to detect weight change of the basket when an item is placed into or removed from the basket.

A mobile weighing apparatus includes a base tubing, a column extending from the base tubing, a handle extending from the column, a plurality of wheels, a weighing platform, and a plurality of load cells coupled to or between the base tubing and the weighing platform. The weighting platform may be suspended from the load cells, such as with wire rope bolts, such that a force applied to the column does not affect weighment of an object on the weighing platform. The apparatus may include a kingpin-less swivel rear wheel, a rear wheel brake to preclude rotation of the rear wheel about an axle of the rear wheel, and an actuator to actuate the rear brake when the rear wheel is in any position over a 360-degree range. The wheels may be positioned adjacent respective corners of a triangularly shaped base tubing, and the apparatus may further include a clinometer.

The present disclosure discloses a smart shopping cart, comprising a shopping basket provided with a cover plate which may be tilted toward the interior of the shopping basket to form an entrance; and the shopping cart further comprises a scanner configured to scan a barcode of a commodity placed on the cover plate to acquire an identity and/or a price of the commodity; a first scale configured to measure a weight of the commodity; a controller configured to generate settlement information of the commodity based on at least one of the identity, the price, and the weight of the commodity, and add the settlement information to a settlement list to update the settlement list; and a display comprising a first display area on which the settlement list is able to be displayed. The present disclosure further discloses a smart shopping system including the shopping cart described above.

The present invention discloses an electronic shopping cart comprising sensor unit, processing unit and display unit. The sensor unit comprises various sensors placed at each corner of the cart and sensory net placed at base of the cart. At least one sensory line connects sensors and sensory net. The sensors generate sensor data by detecting item placed into or taken away from cart. The sensory net detects change in weight of cart and generate sensory net data. The processing unit processes sensor data and sensory net data and accordingly retrieves information of item from at least one item database. Based on retrieved information, processing unit calculates subtotal of item and grand total cost of all items in cart and are displayed to user on display screen long with item details. Sensors, sensory net and sensory line together identifies item added into cart or removed from cart, and maintain integrity of items in basket.

Disclosed herein relates to a system, comprising: at least one load receiver mounted on a shopping cart or basket and configured to receive an item placed into the shopping cart or basket for a weighing operation; a plurality of sensors configured to detect a plurality of parameters relating to the weighing operation of the item including at least one of: a relative angle between a force sensing axis of the at least one load receiver and a direction of gravity, a motion of the shopping cart or basket, and an ambient temperature surrounding the shopping cart or basket and the at least one load receiver; and a processor configured to determine an actual weight of the item based on at least a portion of the plurality of parameters.
