An autonomous luggage cart system and method for transportation of objects in facilities such as hotels, condos, universities, and convention centers, providing a cart having a floor, a bumper, riser pipes, and an underside housing, wheels driven by electric motors, a high-capacity battery and a battery charge manager, front and rear tow hitches and tow-hitch sensors, corner sensors, a camera-sensor package, directional sensors, RFID units, a controller unit applying machine learning and artificial-intelligence methods to sensor data, and a communications unit and a remote unit for external communications with other systems.

The present invention relates to a cart device primarily comprised of a body, at least one wheel, and at least one axle. In one embodiment, the device can be manually pulled using a handle. In another embodiment, the device has a motor that is powered by a battery and can be controlled by a remote such that the device can propel itself. In various embodiments, the wheel of the device can be optimized for various terrain such as sand, wherein said embodiment features a smooth and inflatable wheel. Further, the device is comprised of an umbrella holder that receives an umbrella and allows the device to act as a base for the umbrella. The device is also comprised of a tow hitch and a tow bar that allows the device to be pulled by a secondary vehicle such as, but not limited to, a golf cart.

This application relates to a wheel steering angle adjustment device for a vehicle operated by manpower. The device may include a fixed body including a rotation support, a rotation body, a lift member coupled to the rotation support, a locking switch coupled to the lift member, and a plurality of fixing groove portions in the outer peripheral surface of the rotation support. The device may also include a fixing protrusion protruding from the locking switch and configured to be detachably coupled to the fixing groove portions, a rotation range limiting stopper provided on a lower portion of the lift member, and a rotation guide groove portion provided concavely in an upper surface of the rotation body. As the rotation range limiting stopper becomes stuck on an end portion of the rotation guide groove portion, an angle by which the rotation body is rotatable relative to the fixed body is limited.

A portable surgical robot includes a surgical device and a cart. The surgical device is coupled to the cart. The cart includes a chassis, a mount coupled to the chassis, a carriage pivotally coupled to the mount, and a set of wheels. The carriage includes a first bracket positioned at a first lateral end of the carriage and a second bracket positioned at a second lateral end of the carriage. A first wheel of the set of wheels is coupled to the first bracket and a second wheel of the set of wheels is coupled to the second bracket. The carriage is configured to pivot relative to the mount to prevent at least one of (i) rocking of the portable surgical robot, (ii) fluttering of the first wheel, (iii) fluttering of the second wheel, and (iv) tipping of the portable surgical robot.

A camera crane mobile base for carrying a camera crane includes a first powered remotely controllable steering system having first and second axle assemblies at a first end of a chassis. A second steering system including third and fourth axle assemblies is provided at a second end of the chassis. A first electrically powered remotely controllable propulsion system includes an electric propulsion motor connected to first and second axles in the first and second axle assemblies. A telescoping center post is pivotally attached to the chassis. An on-board hydraulic system may power the first steering system and the telescoping center post.

The device may also include a fixing protrusion protruding from the locking switch and configured to be detachably coupled to the fixing groove portions, a rotation range limiting stopper provided on a lower portion of the lift member, and a rotation guide groove portion provided concavely in an upper surface of the rotation body. As the rotation range limiting stopper becomes stuck on an end portion of the rotation guide groove portion, an angle by which the rotation body is rotatable relative to the fixed body is limited.

Various configurations of picking and packaging carts are disclosed that can be advantageously employed in Ecommerce and retail settings to improve operational efficiency. Examples can preclude the need for a detour from the item retrieval location to a packaging area, prior to delivery to a shipping area, such as a drop-off point. Some examples include a frame; a shelf rack; accessory support units including a printer holder; multiple shipping container support units configured to hold a plurality of shipping containers of a plurality of sizes; and a packaging shelf arrangement comprising a top shelf providing a flat packaging surface.

This invention offers a new hands-free electric powered utility cart, that is controlled by voice commands from the user, and by the cart detecting and tracking an electronic device or chip that a user simply carries or attaches to his or her garments.

Once the cart is powered-on, the user speaks voice commands such as “CART, FOLLOW ME” and the cart will follow approximately three feet behind the user wherever they walk. When the user wants the cart to stop, they can either stop walking, or use a voice command such as “CART, STOP”. The user can voice additional relevant commands such as “CART, FOLLOW TO MY RIGHT, or LEFT”, in order to control the cart's mode of operation.

All kinds of carrying baskets tailored to specific uses such as for beach, shopping, tools, golf equipment, and even a baby carriage are fitted to the cart's standardized chassis.

The present disclosure relates to a smart stroller and a method of controlling the same. The smart stroller includes a sensor part for sensing various information regarding a space in which a baby is seated and information regarding the surrounding environment in which the smart stroller is traveling. The sensed information is transmitted to a controller so as to be calculated as information for controlling operation of the smart stroller or information for informing to a user. This may enable the smart stroller to travel in a stable manner. This may also allow the user to check the state of the baby in real time and take necessary action.

A bidirectional trolley (1) comprising a drawbar (Abstract2), two pivoting front wheels (6, 6′) a push handle (3), a loading and unloading plan (4) for a box (5) for moving items. The bidirectional trolley comprises a rotary system (10), placed in the rear portion of the trolley (1), and comprising two non-pivoting wheels (8′, 8″) placed on the same horizontal axis, a pivoting wheel (8) placed at 45° with respect to the other two non-pivoting wheels (8′, 8″) and a hook (12), configured for assuming a resting position in which it is completely retracted under the plan (4) between the two non-pivoting wheels (8′ and 8″), in order to permit to an operator to approach the most to the box (5) for moving items, for an easy unloading and loading of the box (5) itself.
