摘要： An omni-directional rotational drive mechanism and a moving body in which production and maintenance can be facilitated, while the size can be reduced, by making the number of components smaller. A rotating body provided for a wheel member rotatable about a ring-shaped shaft having a rotating shaft of the wheel member as its center. The rotating body is configured to rotate integrally with the wheel member about the rotating shaft. A pair of worms rotatable about the same shaft as the rotating shaft of the wheel member. A pair of worm wheels are provided for the wheel member so as to be rotatable by meshing with different worms, and capable of transmitting each of rotations to the rotating body. The rotating body is configured so as to rotate or stop with respect to the wheel member in accordance with the rotational direction and the rotational speed of the respective worms.

摘要： The present invention is a personal mobility device having multiple modes of operation, including a deck, and a first and second wheel assembly, and at least one battery powered electric motor, and actuation means. The deck includes an elongate substantially flat body, and each wheel assembly is attached to the deck in the vicinity of a respective end of the elongate body. The respective axle of each wheel assembly is located upon the plane of the deck. The at least one battery powered electric motor is adapted to be actuated via the actuation means when a user steps onto the deck, and adapted to drive the first and second wheel assemblies, and wherein in the first mode of operation, both the first and second wheel assemblies are adapted to roll in a circumferential direction, predominately under the influence of the at least one electric motor, so that the device moves in an orthogonal direction to the longitudinal axis of the deck, and wherein in a second mode of operation, both the first and second wheel assemblies are also adapted to optionally free-roll in an orthogonal direction to the plane of the wheel assembly, thereby allowing the device to move substantially in the direction of the longitudinal axis of the deck. There is a transitional mode of operation, where the device is capable of continuously and smoothly transitioning between the first and second mode of operation, while the device is being ridden.

摘要： Technology is provided for wheel guards that can help lift the wheel of a wheeled vehicle, such as a robot, up and over an obstacle. The wheel guard can include a guard member including a ramped surface extending between a first end portion and a second end portion, the second end portion coupleable to a suspension of a wheel of the vehicle. A pivot mechanism is attached to the first end portion that is coupleable to a chassis of the vehicle, whereby the guard member can pivot with respect to the chassis as the wheel moves up and down.

摘要： An omni wheel, a motion device and a control method thereof are disclosed. The omni wheel includes a center wheel and a plurality of peripheral wheels distributed in a circle with respect to an axis of the center wheel; and a peripheral wheel brake component disposed on the centre wheel and configured to control a resistance of the peripheral wheels during a rotation of the peripheral wheels. The omni wheel solves the problem of low braking performance of the motion device by increasing the resistance of the peripheral wheels during rotation, and avoids any random rotation of the peripheral wheels.

摘要： A robotic vehicle chassis is provided. The robotic vehicle chassis includes a first chassis section, a second chassis section, and a hinge joint connecting the first and second chassis sections such that the first and second chassis sections are capable of rotation with respect to each other in at least a first direction. The vehicle includes a drive wheel mounted to one of the first and second chassis sections and an omni-wheel mounted to the other of the first and second chassis sections. The omni-wheel is mounted at an angle orthogonal with respect to the drive wheel. The hinge joint rotates in response to the curvature of a surface the vehicle is traversing.

摘要： The present utility model refers to a rolling device and, more particularly, an improved multi-directional ball caster-type device having a better contact angle between the ball and the ground. The contact angle of the present improved device is from 62° to 50°, or less. As the contact angle can be smaller, the object supported on the rolling system can be more sloped, for example, a luggage case, without having friction between the main ball involving structure and the ground.
