A contactless power feeding device of an embodiment includes: a placement portion on which a plurality of carts including a device and a power receiving unit that receives power to be fed to the device is placed in a state of being arranged in one direction; a power transmitting unit that is provided at each of placement positions at which the cart is placed in the placement portion and transmits power to the power receiving unit by contactless power feeding; a lock unit that is provided at each of at least a first placement position at which a first cart in the one direction is placed and a second placement position at which a next cart is placed among the placement positions, and locks movement of the cart; and a control unit that controls an operation of the lock unit.

A trolley, for example for a supermarket, including at least one chassis, a load-bearing structure supported by the chassis, a suspension structure supported by the load-bearing structure configured to suspend at least one container. The trolley includes at least one measurement device at least partially carried by the suspension structure and for measuring at least one parameter relating to the weight of the at least one container when the container is suspended from the suspension structure.

Systems and methods are disclosed for foldable containers for manual and robotic use. In one embodiment, an example foldable container may include a first container wall, a second container wall configured to rotate outwards in a first direction with respect to the first container wall, and a bottom container platform configured to rotate outwards in a second direction with respect to the first container wall. The bottom container platform may include an automatic locking mechanism configured to engage with the second container wall when the foldable container is in an unfolded position, where the second direction is perpendicular to the first direction. Some embodiments may include a number of wheels. The foldable container may be configured to be transported using (i) the plurality of wheels via manual pushing, and (ii) robotic manipulation to lift and move the foldable container.

A trolley arrangement is provided comprising a chassis from which a plurality of upwardly extending, rear support posts extend. An upper support frame is fitted to, and extends away from, the rear support posts, the upper support frame being fitted along the length of the support posts so that upper portions of the support posts extend upwardly, so as to protrude, from the upper support frame, the upper support frame comprising a peripheral bar component. A basket can be secured to the upper portions of the support posts, the basket being supported on top of the upper support frame once assembled. The basket comprises a corresponding plurality of elongate corner side wails that are arranged to be adjacent the upwardly extending support posts so that each post is arranged to abut against one of the upwardly extending corner side walls in use.
