Embodiments include strollers having removable seats. An example stroller may include rear wheels, front wheels, and a frame including a handle portion, a rear wheel support portion, a front wheel support portion and a folding mechanism connecting the front wheel support portion and the handle portion in both an unfolded configuration and in a folded configuration. The frame may include a stroller seat support portion positioned at a first vertical position adjacent the handle portion, and a front seat attachment configured for attachment to the front wheel support portion at a second vertical position substantially lower than the first vertical position. The front seat attachment may be configured to support the front stroller seat substantially over the front wheels so that a center of gravity of the stroller system is between the front wheels and the rear wheels.

A material handling cart is provided, having a frame with wheels and engaging members for supporting a part carried by the cart. Each engaging member has an engaging surface including a material for protecting a corresponding surface of the part from damage. Upper supports are attached to the frame and extend upward to a distal end, and have a height equal to or greater than a height of the part when the part is carried by the cart. Each upper support has an upper stacking coupler at its distal end. Lower stacking couplers are attached to the bottom of the frame. The lower stacking couplers engage upper stacking couplers of a second identical cart, to stack the cart above the second cart. The upper stacking couplers engage lower stacking couplers of a third identical cart, to stack the third material handling cart above the cart.

Various embodiments herein relate to powered pusher devices configured to push wheeled objects from one location to another. Further embodiments relate to wheeled objects such as carts for transporting items from one location to another. Other embodiments relate to platform powered pushers that can be coupled to a family of various wheeled objects.

The present invention relates to an electric propulsion system (1) for a rolling object, comprising a frame (2) with at least one motorized wheel (3), and at least one non-motorized wheel (4), a handlebar (6) and coupling means (5). Coupling means (5) are intended for gripping, orientation and lifting of at least one wheel of the rolling load. The means of orienting the wheel of the rolling object orient the wheel perpendicular to the longitudinal direction (x) of the frame.

The various embodiments disclosed herein relate to an interchangeable hitch mechanism that is coupleable to a pusher device. Other implementations relate to a pusher device having such an interchangeable hitch mechanism that can be removably coupleable to a manual jack pallet.

A robotic system that includes a body, a hitch assembly coupled to the body, and a sensor array coupled to the body. The robotic system includes a processor and operating logic containing programming instructions thereon that, when executed, causes the processor to detect, via the sensor array, a location of a vehicle relative to the body. The programming instructions of the operating logic further cause the processor to detect, via the sensor array, a position of a hitch receiver along the vehicle and move the body toward the vehicle to position the hitch assembly proximate to the hitch receiver. The programming instructions of the operating logic further cause the processor to move the hitch assembly relative to the body and in alignment with the hitch receiver and engage the hitch assembly to the hitch receiver to securely couple the body to the vehicle.

Embodiments include strollers having removable seats. An example stroller may include rear wheels, front wheels, and a frame including a handle portion, a rear wheel support portion, a front wheel support portion and a folding mechanism connecting the front wheel support portion and the handle portion in both an unfolded configuration and in a folded configuration. The frame may include a stroller seat support portion positioned at a first vertical position adjacent the handle portion, and a front seat attachment configured for attachment to the front wheel support portion at a second vertical position substantially lower than the first vertical position. The front seat attachment may be configured to support the front stroller seat substantially over the front wheels so that a center of gravity of the stroller system is between the front wheels and the rear wheels.

The present disclosure provides a conveyance system and the like capable of preferably conveying a conveyed object in accordance with a state of the conveyed object. The conveyance system includes a conveyance robot, a drive controller, which is a controller, an image data acquisition unit, and a setting unit. The conveyance robot conveys the conveyed object. The drive controller controls an operation of the conveyance robot. The image data acquisition unit acquires image data obtained by capturing images of the conveyed object. The setting unit sets an operation parameter of the conveyance robot in the drive controller based on the acquired image data.

A convertible handle having a shaft portion and a grip portion. The grip portion is configured to slide along the length the shaft portion to expose a tongue on the shaft portion. In a manual configuration, the grip portion is used for manually pulling a cart. When not in the manual configuration, the shaft may be attached to a vehicle via the tongue for towing by vehicle.

Embodiments herein are directed to a wheelchair system that includes a wheelchair. The wheelchair includes a coupling mechanism, a processing device, and a non-transitory, processor-readable storage medium in communication with the processing device. The non-transitory, processor-readable storage medium includes one or more programming instructions that, when executed, cause the processing device to determine the location of an accessory, position the wheelchair with respect to the accessory, and couple the wheelchair to the accessory via the coupling mechanism. The positioning of the wheelchair is independent from a user physically controlling the positioning of the wheelchair with respect to the accessory.
