Ease of connecting to a robot in a charging station is increased. A charging station includes a base having an upper face up on which a wheel rides, and a power supply terminal to be connected to a charging terminal of a robot. The upper face of the base is such that a target position is set in a far side region, while a reference entrance line that connects an entrance side specific position and the target position is set, and the upper face of the base includes an inverted face of a three-dimensional curved form that provides an entering wheel with a gravitational component that acts toward the reference entrance line side. The power supply terminal is connected to the charging terminal in a state wherein the wheel has arrived at the target position.

An electric weight sensing skateboard using one or more strain gauge systems to detect rider-induced strain on one or both trucks, an inertial sensor to detect accelerations and balance position, and wheel speed sensors. Throttle is controlled by rider position, for example, lean forward to increase speed, lean back to slow down. Several drive methods include a driver position detection velocity setpoint control, torque setpoint control, and direct velocity/torque control. A throttle remote is note required. Rider weight activates the motors.

A universal charging system is disclosed. In one example embodiment, the universal charging system includes a charging adapter configured to be mounted on a light electric vehicle (LEV), a charging station, and a processor configured to control charging of the LEV. The charging adapter may have electrical contacts for docking with a charging station and a charging interface for supplying power from the charging station to a battery of the LEV. The charging station may have at least one docking unit for receiving the charging adapter of the LEV. The at least one docking unit may have further electrical contacts for connecting to the charging adapter of the LEV.

Techniques are disclosed for systems and methods to provide reduction in connectivity interruptions between vehicle docking stations and a management server for facilitating micro-mobility vehicle sharing services. To maintain communication sessions between the vehicle docking stations and the management server, heartbeat signals are transmitted periodically by each of the vehicle docking stations to the management server. An unavailability of the connection between a vehicle docking station and the management server may be detected based on an interruption to the heartbeat signals. In response to determining the unavailability of the connection, the management server may instruct a vehicle within a predetermined distance of the vehicle docking station to establish a short-range connection with the vehicle docking station and retrieve docking station data from the vehicle docking station.

Embodiments include an EVSE unit having a Level 2 or Level 3 charge handle, a receptacle configured to receive the Level 2 charge handle, and a current overage protection unit. The EVSE unit can include a Level 1 outlet including one or more plug outlets configured to receive one or more corresponding Level 1 plugs. A first power meter associated with the Level 2 charge handle can meter power delivered via the Level 2 charge handle. A second power meter associated with the Level 1 outlet can meter power delivered via the Level 1 outlet. A charging logic and relay section can intelligently allocate power between the Level 2 handle and the Level 1 outlet according to charging rules. The current overage protection unit can ensure compliance with local ordinances and protect internal components of the EVSE unit.

A mobility device comprising a motorized shoe to be worn by a user to increase the speed of walking. The motorized shoe has a plurality of wheels, with at least one wheel driven by an electric motor through a geartrain. On onboard controller gathers data from at least one of an inertial measurement unit, an ultrasonic sensor, and a vision system to generate a command speed to the electric motor. A user wearing a pair of the mobility devices, one on each foot, is able to walk with a normal gait, but at an increased speed.

Embodiments include a multi-level electric vehicle supply equipment (EVSE) unit. The multi-level EVSE unit can include a Level 2 charge handle, a receptacle configured to receive the Level 2 charge handle, and a Level 1 outlet including one or more plug outlets configured to receive one or more corresponding Level 1 plugs. The Level 2 charge handle can be permanently attached to the multi-level EVSE unit via a cable. The Level 1 outlet can temporarily receive the one or more corresponding Level 1 plugs. A first power meter associated with the Level 2 charge handle can meter power delivered via the Level 2 charge handle. A second power meter associated with the Level 1 outlet can meter power delivered via the Level 1 outlet. A charging logic and relay section can intelligently allocate power between the Level 2 handle and the Level 1 outlet according to charging rules.

A child vehicle includes a power mechanism having a motor, at least one wheel selectively operatively coupled to the motor, and a propulsion switch coupled to the power mechanism and having a first position and a second position. The first position is from a user-initiated force. The propulsion switch automatically moves to the second position upon disengagement of the force. In the first position, the child vehicle is in the first operational mode and the wheel is being driven by the motor. In the second position, the child vehicle is in the second operational mode and the wheel is allowed to rotate substantially free from drag or resistance due to the motor. A method is also disclosed.

A ride-on toy with electronic speed controller for superior user experience is described herein. A ride-on toy as described herein may be in the form of a ride-on toy car, truck, jeep, motorcycle or the like and may be used with up to a 24-volt power source as opposed to a 12-volt power source as is common in the art. An electronic speed controller of the present disclosure provides variable speed control to at least one and preferably at least two motors from separate accelerator and brake mechanisms such as pedals. Conventional ride-on toys such as those described herein typically contain a single-pole switch such as pedal that provides all-or-nothing power to a motor as opposed to modulation of two motors by two actuation means. A ride-on toy as described herein may combine various controller components in unique ways to achieve the superior results as described herein.

A universal charging system is disclosed. In one example embodiment, the universal charging system includes a charging adapter configured to be mounted on a light electric vehicle (LEV), a charging station, and a processor configured to control charging of the LEV. The charging adapter may have electrical contacts for docking with a charging station and a charging interface for supplying power from the charging station to a battery of the LEV. The charging station may have at least one docking unit for receiving the charging adapter of the LEV. The at least one docking unit may have further electrical contacts for connecting to the charging adapter of the LEV.
