An autonomous coverage robot includes a chassis having forward and rearward portions and a drive system carried by the chassis. The forward portion of the chassis defines a substantially rectangular shape. The robot includes a cleaning assembly mounted on the forward portion of the chassis and a bin disposed adjacent the cleaning assembly and configured to receive debris agitated by the cleaning assembly. A bin cover is pivotally attached to a lower portion of the chassis and configured to rotate between a first, closed position providing closure of an opening defined by the bin and a second, open position providing access to the bin opening. The robot includes a body attached to the chassis and a handle disposed on an upper portion of the body. A bin cover release is actuatable from substantially near the handle.
Abstract:
A vehicle is provided comprising a battery, a charge plate electrically connected to the battery, and a thermal sensor configured to output a signal indicative of a sensed temperature. The thermal sensor can be positioned to determine temperature in the area proximate to the charge plate. The vehicle further includes at least one controller configured to (a) cause an association signal to be repeatedly transmitted during a battery charge procedure such that charging of the battery via the charge plate is maintained, and (b) in response to the sensed temperature exceeding a primary threshold, cause the repeated transmission of the association signal to be interrupted such that charging of the battery ceases.
Abstract:
An automatic moving device and a control method therefor. The automatic moving device comprises a battery pack providing power. The automatic moving device can work within a working area and automatically return to a charging station for charging. The control method comprises the following steps: monitoring the power level of the battery pack; if the power level of the battery pack is less than or equal to a preset power level, initiating an action of returning the automatic moving device to the charging station; and after a preset time period, stopping the travel. By setting a preset time period simultaneously with initiating a return action, and executing a return action within the preset time period, the control method prevents damage to the battery pack from over-discharging caused by the automatic moving device continually returning, thus achieving the effects of protecting the battery pack and extending the life thereof.

Abstract:
Provided are an electric automobile to which a power supply device supplies power, and an electricity supply system capable of accurately associating the power supply device and the electric automobile carrying out communication therewith. A power supply-side control unit (24) controls such that electricity that a power supply unit (21) supplies reaches a first electricity quantity Pa before a power supply-side communications unit (23) receives a request signal from a vehicle-side communications unit (43), and controls such that electricity that the power supply unit (21) supplies reaches a second electricity quantity Pb, which is greater than the first electricity quantity Pa, after the power supply-side communications unit (23) receives the request signal from the vehicle-side communications unit (43). The vehicle-side communications unit (43) activates on the basis of the first electricity quantity Pa received from the power supply unit (21) of a power supply device (2).
