A cargo carrier for mounting on a mobile cart, comprising: a base configured to be releasably attached to a top surface of the mobile cart; first and second opposing side walls, each having a bottom edge attached to the base, a top edge, a front side edge running from the bottom edge to the top edge and a rear side edge running from the bottom edge to the top edge; a front end wall, having a bottom edge hingedly connected to the base so as to hinge between a closed position and an open position, wherein in the closed position, a first front end wall side edge fits against the front side edge of the first side wall, and a second front end wall side edge fits again the front side edge of the second side wall, to thereby close a front end of the cargo carrier; and in the open position, the front end wall is generally parallel to the base, to thereby open a front end of the cargo carrier; a front end wall lock for releasably locking the front end wall in the closed position; a rear end wall, having a bottom edge hingedly connected to the base so as to hinge between a closed position and an open position, wherein: in the closed position, a first rear end wall side edge fits against the rear side edge of the first side wall, and a second rear end wall side edge fits again the rear side edge of the second side wall, to thereby close a rear end of the cargo carrier; and in the open position, the rear end wall is generally parallel to the base, to thereby open a rear end of the cargo carrier; a rear end wall lock for releasably locking the rear end wall in the closed position; whereby the cargo carrier can be converted between a four-walled bin, for containing objects within its four walls, to an open ended cargo carrier, allowing elongated objects in the cargo carrier to extend beyond the front end wall and/or the rear end wall by hingedly moving the front end wall and/or the rear end wall, respectively, between the closed and open positions is disclosed.

A system for mounting a stowed component on a self-propelled cart, comprising: the self-propelled cart comprising: a body having a top, bottom, front end, rear end, left side, and right side, and further comprising: a battery compartment, and a platform; a battery housed in the battery compartment; a controller; four arms, each pivotably attached at a first end to the body; four wheels, each connected to a second end of one of the four arms; four arm actuators, each configured to pivot one of the four arms such that each wheel can be moved closer to or further away from the body; and at least two motors, each configured to rotate one wheel and each independently controlled by the controller, whereby the controller can move the cart; at least one sensor for determining the position of the component to be mounted on the cart; wherein the controller can adjust the height of the cart by pivoting one or more of the four arm actuators and control the yaw of the cart by rotating one or more of the wheels; and wherein the cart is configured to approach a location of a component and adjust its orientation to compliment an orientation of the component to thereby facilitate mounting of the component on the cart is disclosed.

A self-docking, motorized cart, comprising: a body comprising a battery compartment and a platform; a battery housed in the battery compartment; a cart docking attachment arm; a controller; four arms, each pivotably attached at a first end to the body; four wheels, each connected to a second end of one of the four arms; four arm actuators, each configured to pivot one of the four arms such that each wheel can be moved closer to or further away from the body; wherein the controller adjusts the height of the cart by pivoting one or more of the four arms; and at least two motors, each configured to rotate one of the four wheels, each independently controlled by the controller, whereby the controller can move the cart and control the yaw of the cart by rotating one or more of the four wheels; whereby the cart can be moved into an appropriate position and orientation for connecting the docking arm attachment to a docking station by the controller selectively pivoting the arms and rotating the wheels; and wherein the docking attachment arm comprises connections for electricity or data is disclosed.

A powered lift hand truck with a corresponding method of operation and control. The apparatus includes a powered lift hand truck configured to lift a load from a lowered to a raised position (and vice versa). The system uses the rotational speed to measure linear speed and enforce a consistent speed of the load. The system is programmed to lift/lower loads at the same speed, regardless of load overall weight. If, for example, the load is heavy, the system determines that the speed is below a predetermined threshold and increases the power so as to increase speed.

A stabilization device for stabilizing an attachment component relative to movements of a basic component which occur outside a permitted plane of movement. The attachment component and the basic component are connected via a stabilization arrangement that includes: a first compensation arrangement for compensating rotational movements of the basic component with respect to an intermediate component, about rotational axes lying in the plane of movement, including a first compensation device which can be actuated actively, a second compensation arrangement for compensating residual linear movements of the intermediate component in a compensation direction, perpendicular to the plane of movement, in relation to the attachment component, having a second compensation device which can be actuated actively, a plurality of inertial sensors assigned to the first and/or second compensation arrangement, and a control device for actuating the compensation devices for movement compensation as a function of sensor data of the inertial sensors.
