The present invention provides a dual-purpose camper capable of being towed by a bicycle and manually, including vehicle frames and a bicycle beam; a pull rod is rotatably connected between the two vehicle frames; a front bracket and a rear bracket are rotatably connected between the front end and the rear end of one side of the vehicle frames opposite to the pull rod; a fixing rod is rotatably connected in a fixing block; and the top end of the fixing rod penetrates through and is slidably connected with a sliding rod. A stable triangular structure is formed by a supporting rod and a second connecting rod; and the downward pressure of the vehicle frames after heavy loading is supported. The direction can be rotated and adjusted arbitrarily by a fisheye bearing to ensure the stability and directional control in the towing process of a bicycle.

A movement assisting tool (23) includes an attachment portion (24) that can be attached to and removed from a main body portion (11) of a battery unit (4), leg portions (25) that are coupled to the attachment portion (24) and extend from the attachment portion (24), and moving wheels (26) that are supported by extension portions of the leg portions (25). In a state where the attachment portion (24) has been attached to the main body portion (11) of the battery unit (4) and the moving wheels (26) are touching the ground, the battery unit (4) can be kept in an inclined orientation in which the wheels (13) are touching the ground and ground contact portions (14) are raised above the ground.

A platoon of electric pallets (e-pallets) includes a follower e-pallet connected to or in wireless communication with a leader e-pallet. The platoon also includes a sensor suite, road wheels, an electric powertrain system, and a local controller. The sensor suite includes a velocity sensor configured to measure a velocity of the follower e-pallet, an angle sensor configured to measure an azimuth angle between the follower and leader e-pallets, and a length or distance sensor configured to measure a distance therebetween. The local controller executes a method to adaptively move a variable target point (VTP) on the leader pallet in response to the velocity, the azimuth angle, and the length, and to thereafter control a dynamic output state of the electric powertrain system using the VTP.

Disclosed is a pusher lift cart comprising a pusher lift cart main frame having a first interfacing member and a second interfacing member configured to telescoping engage a first complementary interfacing member and a second complementary interfacing member, wherein the pusher cart main frame is configured to receive and move an axle.

An improved auto-chocking enabled cargo dolly that is towable by ground support equipment. The dolly has a frame, wheels attached to the frame that support the frame and rotate to allow movement of the frame, a tow bar, a linkage in communication with the tow bar and that actuates when the tow bar is raised, and a wheel engagement chocking system fixed to the dolly frame and disposed to selectively engage at least one of the wheels attached to the dolly frame. The wheel engagement system is responsive to a position of the linkage, where the wheel engagement chocking system applies pressure directly to at least one of the wheels to hold the wheel(s) in place when the linkage is actuated by the tow bar.

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 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.

An automatic guided vehicles (AGV) can include: motors, wheels, motor controllers, and batteries coupled to an elongated frame. The two wheels can be mounted on opposite sides of the elongated frame. The wheels can be coupled to motors which can be controlled by motor controllers. The motors and motor controllers can be attached to the frame. The center of gravity can be lower than the axis of rotation of the wheels so that the AGV will passively rotated into an upright position. A connector flange can be mounted on top of a payload holder column mounted to a center portion of the AGV frame. Objects can be mounted on or towed by the connector flange.
