A wheelbarrow with an electric motor built into the wheel helps the user to push and brake the wheelbarrow. A sensor is installed on the handle support, which detects the position of the hand in the axial direction. A button is mounted on the handle support next to the handle. There is an acceleration sensor and a gyroscope on the wheelbarrow. Based on the axial movement of the hand, the wheelbarrow controller calculates the pushing or pulling force of the arms on the handles. The operation of the electric motor is controlled by the wheelbarrow controller via the motor controller, based on the information received from the motor controller, the detected sensor values and the switch status. As a result, the force of the electric motor can be used effectively for an additional drive or braking, so that the required push force of the arms can be reduced. When braking, the motor acts as a generator and charges the battery. Two batteries are placed in the supported legs of the wheelbarrow, which contributes to the weight balance of the wheelbarrow and allows good cooling of the batteries. The construction of the frame provides battery protection and is adapted to transportation on a towing hitch of a passenger car.
