    Abstract: A remote controlled actuator includes a spindle for holding a tool, a spindle guide section of an elongated configuration, a distal end member rotatably supporting the spindle, and a drive unit housing connected to a base end of the spindle guide section. The distal end member is fitted to the spindle guide section for alteration in attitude. The spindle guide section includes an outer shell pipe, a rotary shaft, and guide pipe. Within the guide pipe, an attitude altering member is inserted to alter the attitude of the distal end member. A connection device detachably connects the spindle guide section with the drive unit housing.

    Abstract: An electric vehicle includes a slip ratio estimator to estimate a slip ratio of a drive wheel on a road surface based on a detection value indicating a vehicle travel speed and a drive wheel rotational frequency; an applied torque estimator to estimate an entire torque applied to the drive wheel based on motor torque command value or motor current value of a motor unit and the torque estimated by a disturbance observer attributable to external force; a coefficient of friction estimator to estimate a coefficient of friction between a road surface and a tire of the drive wheel, based on the estimated torque and the estimated slip ratio; and a motor torque command value limiter to limit, based on a determined maximum acceptable torque, the motor torque command value to the motor unit that is generated responsively to an acceleration manipulation unit and a deceleration manipulation unit.
