A corner module apparatus for a vehicle includes a driving unit configured to provide driving power to a wheel of the vehicle; a braking unit, coupled with the driving unit, configured to apply or release braking power; an upper arm module, connected to the driving unit, adjustable to vary a camber angle of the wheel; a lower arm module, connected to the driving unit, configured to absorb road surface impact while the vehicle moves; and a steering unit configured to support the upper arm module and the lower arm module, and adjust a steering angle of the wheel.

A vehicle wheel suspension of a control blade design has three wheel-guiding control arms essentially oriented in the transverse direction of the vehicle and one longitudinal control arm fastened rigidly to the wheel carrier and barely limiting its transverse movement with respect to the vehicle body. The longitudinal control arm is constructed of a fiber composite material and is also rigidly fastened to the vehicle body and thereby takes over the function of a main spring between the wheel carrier and the vehicle body. Other than stop springs integrated in a vibration damper, no further main spring element is provided between the wheel carrier and the vehicle body. The above-mentioned longitudinal control arm may be formed by two, in a wide area, individual control arm parts, which are essentially situated in a common vertical plane, specifically such that the first control arm part of the longitudinal control arm is fastened to the wheel carrier above the wheel center, and second control arm part is fastened to the wheel carrier below the wheel center. The two control arm parts, guided together with their other ends in a common fastening element, are, as required, slightly elastically fastened to the vehicle body.

An autonomous mobile robot is provided. The autonomous mobile robot includes an upper module including a cargo space provided therein, and a cover, a lower module positioned under the upper module and providing a driving force, a driving module provided in the lower module, and a control unit that controls an operation of the driving module, in which the driving module includes a plurality of pairs of wheels capable of asynchronously contacting a road surface or ground so as to overcome a step or a stair.

An X-shaped spring for a transportation vehicle wheel suspension system having, per wheel side, a first leaf spring and a second leaf spring made from fiber-reinforced arranged to lie above one another and combined at a respective first end on a first fastening device for transportation vehicle body-side support, wherein the first leaf spring has a second fastening device at its second end for wheel-side support, and the second leaf spring is supported at its second end on the transportation vehicle body side. Towards its second end, the second leaf spring is an arc section curved away from the first leaf spring.
