A running wheel for a patient positioning device (30) is provided. The running wheel has a wheel (1) and a receiving device (4) for rotatably receiving the wheel (1) around a first rotational axis (5), which is arranged centrally with respect to a circumference of the wheel (1). The wheel (1) has a wheel body (3), and multiple circumferential castors (7), each having a second rotational axis (8) arranged in a direction tangential to a circumference of the wheel (1), wherein the circumferential castors (7) form a bearing surface of the wheel (1).

Provided is a tool system for including a machine tool configured for machining by the removal of material an object defining a machining surface.

Disclosed is a mecanum wheel, including a mecanum wheel body and a drive device. A wheel axle hole is formed in the mecanum wheel body. The drive device is partially or completely arranged in the wheel axle hole. The axis of a connecting shaft of the drive device is collinear with a rotary shaft of the mecanum wheel body, and the mecanum wheel body rotates along with a housing of the drive device. Further disclosed are a mecanum wheel with a shock absorbing device, a chassis including at least one pair of mecanum wheels, and an assistant robot including a chassis.

In a propulsion device including a main wheel having a plurality of driven rollers fitted on and arranged circumferentially along an annular core member so as to be rotatable around tangential lines of the annular core member at respective positions thereof on the annular core member, a pair of drive disks positioned on either side of the main wheel in an individually rotatable manner, a plurality of drive rollers supported along an outer periphery of each drive disk so as to be each rotatable around a rotational center line extending in a skewed relationship to a rotational center line of the corresponding drive disk, and a drive unit for individually rotatively driving the drive disks, a plurality of guide rollers are rotatably supported by a body frame and engage at least one driven roller not engaged by any of the drive rollers from either side.

A modular low-floor transport system comprises at least one drive module and at least one carrier module. The drive module includes a drive base and a drive chassis connected to the drive base. The drive chassis includes at least one driven wheel coupled to a drive. The carrier module includes a carrier base and a carrier chassis connected to the carrier base. The carrier chassis includes at least one non-driven carrier wheel. The drive base and the carrier base are rigidly connected to each other with respect to a stroke direction, and the drive chassis is movably mounted in the stroke direction to the drive base.

A rotary drive device includes a pair of drive force transmissions, a pair of decelerators, a pair of carriers, and at least one coupler. Driving rollers are included in the pair of drive force transmissions. Driving rollers transmit drive force to a main wheel. The main wheel includes driven rollers. The pair of drive force transmissions are rotatable about a rotation axis. The pair of carriers accommodate at least a portion of the decelerators. The pair of carriers oppose each other in an axial direction along the rotation axis. The pair of carriers include a first carrier and a second carrier that are directly or indirectly coupled by the at least one coupler.

An omnidirectional rotation drive device includes a knuckle connected to a vehicle body, a wheel body configured to rotate around the knuckle, a plurality of sub-wheel units rotatably supported on the wheel body, and a bevel gear located in the wheel body and configured to rotate around the knuckle. The plurality of sub-wheel units is rotated depending on a difference between an angular speed of the wheel body and an angular speed of the bevel gear.

A mecanum wheel includes a first wheel frame having a circumference and a plurality of first mounting mechanisms spaced about the circumference. There is a second wheel frame having a circumference and a like plurality of second mounting mechanisms spaced about the circumference. There are a plurality of roller units, each having a roller surface and a hollow center cavity. There is an axle disposed in the hollow center cavity of each roller, and a first end of the axle is connected a first mounting mechanisms and the second end of each axle is connected to the second mounting mechanism. The first end of each axle includes an angled tip portion with a substantially flat surface.
