摘要： A wheel for an omnidirectional moving device includes an annular core body formed by connecting joint members in an annular shape, and free rollers rotatably supported by the core body. Each of the joint members includes a shaft portion having a first end and a second end, a first connecting portion provided at the first end, and a second connecting portion provided at the second end. Each of the free rollers is rotatably supported by the shaft portion of the corresponding joint member. The first connecting portion of each of the joint members is rotatably connected to the second connecting portion of the adjacent joint member. The first end of each of the joint members abuts on the second end of the adjacent joint member so that a rotation range of the adjacent joint members is restricted. A cushioning material is provided between the first end and the second end.

摘要： The disclosure provides a wheel for an omnidirectional moving device which takes fewer man-hours for manufacturing, and a manufacturing method of the wheel for an omnidirectional moving device which takes fewer man-hours. The wheel includes an annular core body 36; a plurality of bearings 75 each including an inner ring 76 and an outer ring 77 relatively rotatable with respect to the inner ring, and the inner ring being fixed to an outer peripheral surface of the core body; and a plurality of rollers 37 each fixed to the outer ring and rotatably supported by the core body via the bearing. The inner ring is tightened and fitted to the core body.

摘要： An omni-directional wheel for a pool vacuum head includes a first frame and a second substantially identical frame, each frame having a hub rotating around a common axis, lower supports extending radially from the hub, risers extending from the hub along the common axis, and upper supports individually coupled to the risers, the upper supports extending radially from the common axis. Rollers coupled to the first frame and the second frame, are radially spaced from the common axis on each frame. The rollers rotate normal to the common axis to impart omni-directional movement. When the first frame and the second frame are interlocked, the risers on the first frame engage the hub on the second frame, and the lower supports on the first frame engaging the upper supports on the second frame, maintaining the rollers in a staggered arrangement around the wheel.

摘要： A wheel and a vehicle each having a simple structure and capable of moving over a step while maintaining stability at flat ground traveling are provided. A wheel includes an outer ring that rotates about a wheel rotational axis, an arm drive gear that rotates independently from the outer ring about the wheel rotational axis, and an arm capable of rotating about an arm rotational axis fixed to the outer ring, the arm being configured to partially protrude outside from an outer peripheral surface of the outer ring in a radial direction as the arm drive gear rotates relative to the outer ring in one direction (normal rotational direction) and to be housed inside in the radial direction from the outer peripheral surface of the outer ring as the arm drive gear rotates relative to the outer ring in the other direction (reverse rotational direction) opposite to the one direction.

摘要： An omnidirectional wheel and a three-wheeled vehicle using the same are provided. The omnidirectional wheel includes a tire that is formed in the shape of an open torus having an open portion and a main rotation unit that is connected to the tire to rotate the tire about a main rotation axis passing through the center of an inner opening formed in a circular hole shape by the tire. A circumferential rotation unit connects opposite ends of the tire that form the open portion therebetween and rotates the tire about a circumferential axis formed in a circumferential direction of the tire to move the tire in a direction parallel to the main rotation axis.

摘要： Disclosed is a mobile robot adapted to traverse vertical obstacles. The robot comprises a frame and at least one wheel positioned in a front section of the robot, at least two middle wheels and at least two rear wheels. The at least one middle wheel and at least one rear wheel are connected by a tilting lever that is arranged on each of the opposing sides of or to the frame, forming a pair of wheels. Each tilting lever can be turned around a lever bearing located between the respective axial centers of rotation of each pair of wheels.
