摘要： A moving vehicle includes a skid-steer electric motor vehicle chassis that is capable of traveling and an optical sensor provided on the electric motor vehicle chassis. The electric motor vehicle chassis includes a chassis body, a plurality of wheels that are provided as pairs of right and left wheels at the front and rear of the chassis body, and a driving unit that individually rotation-drives the pairs of right and left wheels. The optical sensor is disposed, in planar view, at a position nearby an axle line of a pair of right and left wheels on one side of the front and rear. A pair of right and left wheels on the other side of the front and rear is configured of wheels with rollers each having a wheel body and a plurality of rollers provided on an outer circumferential portion of the wheel body.

摘要： The present invention provides a battery-driven traveling device including: a framework section disposed on at least a bottom part of a vehicle body for ensuring strength of the vehicle body; two slide rails being composed of a left slide rail and a right slide rail and being supported by the framework section and extending substantially horizontally; a battery supporting member that is mounted to be insertable into the vehicle body and extractable from the vehicle body by using the two slide rails; and a plurality of dampers disposed on a path through which vibration of the vehicle body is transmitted from each of the slide rails to the battery supporting member for relaxing the vibration transmitted from the vehicle body to the battery while the device travels, wherein the left slide rail is disposed on left side of the battery supporting member and the right slide rail is disposed on right side of the battery supporting member, and each of the dampers is disposed above or below the left slide rail or the right slide rail.
