A system may include a vehicle having a storage area and a guide rail configured to extend from the storage area. The system may further include a robot having a support portion comprising a placement surface and a base. The robot may also include a plurality of descendible wheels. The robot may also further include a plurality of legs, each connecting the support portion to one of the plurality of descendible wheels.

Disclosed herein are a cart moving in parallel with an installed object and a method of moving the same, the cart, which moves in parallel with an installed object, according to an embodiment including a control unit that senses obstacles around the cart, detects lines of installed objects around the cart, and then generates a moving route of the cart.

A cart that follows a transmission module based on position information of the transmission module and a method for moving the cart are provided. According to an embodiment of the present disclosure, the cart accumulatively stores the position information of the transmission module and generates a moving path based on the position information of the transmission module and moves.

Disclosed a dual-function electric stair-climbing vehicle. A bicycle-like saddle is mounted at an upper part of a frame of the vehicle; and a worm gear reducer is mounted at a middle part of the vehicle for driving two rotating legs to climb up or downstairs. The vehicle is mainly used for fire rescue in high-rise buildings, equipment maintenance of high-rise buildings when no elevator is available, and fast transportation of equipment, materials and firefighters or maintenance men upstairs. When the width of a corridor is greater than 1.1 m, the vehicle can be rode upstairs directly with people and goods; when the width is less than 1.1 m and greater than 0.9 m, people need to get off and make a turn; and when the width is less than 0.9 m, the vehicle is not available. The dimension of the frame is about 1200550380 mm.

A method of operating a payload-carrying vehicle having two laterally disposed wheels positioned along a central axis is described. The method includes measuring a force applied by a user to the hand truck, where the measured force comprising a direction and a magnitude, and providing torque to each wheel to cause each wheel to rotate in a respective direction as a function of the measured magnitude and direction. The amount of torque provided to each wheel in response to the force from the user is such that the magnitude of measured force applied by the user is not greater than a predetermined threshold value.

A wheel includes a supporting frame, with a central portion having a center around which the wheel can turn, and a plurality of radial portions extending from the central portion angularly displaced with each other. A housing seat is delimited between two adjacent radial portions. A movable element is radially displaceable between a first working position located at a maximum distance with respect to the center, and a second working position located at a minimum distance with respect to the center of the central portion. The radial portions and the movable element have respective distal sections, with respect to the center, curved with a curvature radius corresponding to the curvature radius of the wheel and being flush with each other. A locking element is displaceable between one locking position, wherein it abuts on the movable element and prevents the radial displacement thereof, and one unlocking position, wherein it allows the radial displacement of the movable element toward the second working position. A returning element of the movable element between the supporting frame and the movable element is configured to bring the movable element back into the first working position. A band made of an elastically deformable material surrounds the distal sections of the plurality of radial portions and the movable element, at the circular perimeter of the wheel.

The current invention may be to provide a modular luggage system having an at least one modular bag that may be configured to be secured to a cart configured to be fully-collapsible. In this embodiment, the collapsible adjustable cart may be configured in a nested configuration such that it may be a unibody structure that may be easily collapsed and stored, preferably in one or more modular bags. In this embodiment, the cart may further include a plurality of telescoping arms coupled to a base support as well as a plurality of extendable wheels secured to the base support through at least one wheel coupler. The adjustable support surface may be expandable through the use of one or more collapsible surfaces such that it may better accommodate one or more modular bags. The invention may also provide a belt-mounted stair guide mechanism to assist a user maneuver an adjustable cart up stairs, or other irregular elevated surfaces.

A firewood delivery and storage system wherein a rack is loaded with firewood at a first origin position. The rack is placed on a wheeled dolly and then transported to a second storage and use position. The rack is then removed from the wheeled dolly. Thereafter, the customer can access the firewood, or move the firewood rack with a dolly or hand truck to a desired location.

A transport apparatus includes a body; a fork having one portion supported by the body and another portion protruded from the body; a lifting unit; a control unit; a primary rotatable member mounted at a front end portion of the fork; an auxiliary rotatable member mounted at a rotatable-member-attaching position of the fork closer to a front end portion or a rear end portion of the fork compared to the primary rotatable member; and a step detection unit, disposed at a detection-unit-attaching position of the fork closer to the front end portion or closer to the rear end portion of the fork compared to the auxiliary rotatable member, and the step detection unit configured to detect a step member of a carriage base. The control unit lowers the fork using the lifting unit in response to a detection of the step member by the step detection unit.
