In accordance with an embodiment, a mobile infant care device includes a carrier having an inner space configured to hold an infant positioned therein, and driving wheels provided at a lower part of the carrier; a monitoring system affixed to the carrier and configured to monitor a state of the infant positioned in the inner space of the carrier; a driving system coupled to the driving wheels, the driving system configured to move a position of the carrier by driving the driving wheels; a communication system configured to wirelessly transmit a monitoring result of the monitoring system to a user terminal device or to wirelessly receive an operation input from the user terminal device; and a controller configured to cause the driving system to move the carrier based on the monitoring result of the monitoring system or the operation input received through the communication system.

An improved movable decorative base assembly is provided that includes a receptacle having a bottom, at least one upstanding side wall forming a hollow interior and an open top. The base assembly includes a wheeled, base carriage on which the receptacle may be placed. The decorative base assembly further includes a pole receiver, which is carried by the base carriage and has a receiving hole for attaching a tube or other elongated body carrying a parasol canopy. The receiving hole of the pole receiver aligns with a through hole in the bottom of the receptacle, allowing the elongated body to extend through the receptacle and attach to the pole receiver, the assembly forming a unitary body which can be rolled on a floor or surface. The decorative base assembly allows safe, comfortable, and stable maneuvering, while alleviating physical strains otherwise felt by those utilizing alternative assemblies.

Provided is a cart robot having a charge function, which includes: a main body having a container in which goods are contained, a handle assembly installed on one side of the container, a battery module, and a battery management system (BMS) module for managing charge and discharge of the battery module; wheel assemblies rotatably coupled to a lower portion of the main body, and configured to move the main body in a direction of a force applied to the handle assembly; and an external charge module (CM) having a front connector provided on a lower front side of the main body and a rear connector provided on a lower rear side of the main body, electrically connected to an external power supply through the front or rear connector and configured to charge the battery module.

A following target identification system is used for identifying a following target of a moving object configured to move autonomously. The following target identification system includes: a portable information generation terminal having a wireless communication function and configured to generate following target information about a movement of the following target in a state where the information generation terminal is carried by the following target; a communication unit included in the moving object and configured to receive the following target information sent from the information generation terminal via wireless communication with the information generation terminal; and a following control unit included in the moving object and configured to determine a position of the following target based on the following target information.

A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

A pallet sled includes a base and a pair of tines extending from the base. A load wheel supports outer ends of each of the tines. A wheel supports the base. At least one motor is configured to drive the base wheel or at least one of the load wheels for driving the pallet sled. The motor may be a hub motor inside the base wheel or the load wheel.

Pram or pram frame, comprising at least one motor, in particular an electric motor, for the assisted driving of the pram or pram frame, a push bar for pushing the pram or pram frame, at least one force sensor device for detecting a direction and/or an amount of a force and/or a force component which acts on the push bar, and/or for detecting a variable derived from this force or force component, in particular a torque and/or a change of the force or force component over time, at least one velocity sensor device for determining a velocity of the pram or pram frame, and at least one control unit, which is configured in such a way that the motor assistance is adapted in dependence on a comparison of the measured force and/or force component and/or the variable derived therefrom to a force threshold value, wherein the force threshold value is established in dependence on a comparison of the measured velocity to a velocity threshold value.

The invention relates to a stroller frame, comprising a sensor unit for capturing sensor data and a drive unit comprised of a computing unit, which is designed to switch the drive unit between a driving state and a non-driving state according to the time curve of the sensor data.

A dolly for indoor and outdoor use including a supporting frame extending along a main axis of extension and a loading platform mounted above said frame. The dolly also includes at least one steering and drive wheel coupled to the bottom of the frame and at least one pair of idle wheels coupled to the bottom of the frame and positioned symmetrically relative to the main axis of extension. The dolly also includes a control structure including a plurality of sensors configured for measuring a plurality of operating parameters of the dolly and for generating respective signals representing operating parameters and a processing unit configured to receive the representative signals and to impart a steering command to the at least one steering and drive wheel at least as a function of the representative signals.

A pallet lift includes a base and a deck extending forward of the base. Load wheels support the deck. A platform above the deck is pivotable relative to the base. The platform has an upper support surface for supporting objects thereon. The platform may be pivoted as the pallet lift travels on an inclined surface, such as a truck ramp, in order to keep the platform relatively level relative to gravity to increase stability.
