    摘要： The invention describes a mecanum wheel comprising a plurality of rollers each with a rolling surface and an axel and a wheel frame for mounting the rollers with mounting units holding respective axel ends of each roller. Each mounting unit comprise a mounting unit recess with an opening, wherein the mounting unit recess interacts with the respective axel end for locking the roller against movements in directions having a component radially inwards. Each mounting unit further comprise a rebounding roller retaining structure positioned at least partly inside an insertion path causing resistance when the axel end is pushed or pulled past the roller retaining structure into, and out from, a resting position in the mounting unit recess, thus preventing unintended release in a radial outward directed component.

    摘要： A calibration method for a moving body, which includes a pair of left and right omnidirectional wheels, includes: a first step of creating a rotational speed command value for four electric motors such that the moving body performs a linear translational movement or an ultra-pivotal turn; a second step of driving each motor based on the command value to move the moving body; a third step of obtaining a total number of rotations of each motor until the movement of the moving body is completed; a fourth step of measuring an yaw angle change amount of the moving body as it moves; a fifth step of repeating the first to fourth steps at least three times to obtain three or more data sets including the total number of rotations of each motor and the yaw angle change amount; and a sixth step of calculating each correction value based on the data sets.

    摘要： A mobile body includes: left and right driving wheels provided on a main body; a drive unit for driving each of the driving wheels; left and right swivel casters; and a controller for controlling the drive unit. The controller includes: an estimation unit for estimating a front-rear distance between a ground contact position of the swivel caster and a center of gravity; a limit velocity calculation unit for calculating a stability limit velocity based on the front-rear distance estimated by the estimation unit, a front-rear distance between a ground contact position of the driving wheel and the center of gravity, a cornering power of the driving wheel, and a cornering power of the swivel caster when a predetermined calculation condition is satisfied; and a driving control unit for controlling the drive unit such that a velocity of the mobile body is less than or equal to the stability limit velocity.

    摘要： The present technology pertains to a mobile object configured so that a mobile object which performs multi-leg movement can stably move. The mobile object includes a body, a front left leg having a front left wheel, a front middle leg having a front middle wheel, a front right leg having a front right wheel, a rear left leg having a rear left wheel, a rear middle leg having a rear middle wheel, a rear right leg having a rear right wheel, and an operation control unit, the mobile object further including at least one of: a combination in which the left and right front wheels are drive wheels driven by the operation control unit, and the rear middle wheel is an omnidirectional wheel; or a combination in which the left and right rear wheels are drive wheels driven by the operation control unit, and the front middle wheel is an omnidirectional wheel. The present technology can be applied to, for example, a mobile object that transports a cargo.

    摘要： The invention provides a caster having a wheel and a wheel lock assembly that is configured to lock the wheel against rotation about a first axis. The wheel lock assembly allows the caster to move between a locked configuration, in which the wheel is engaged by a detent of the wheel lock assembly, and an unlocked configuration, in which the detent is spaced from the wheel. In certain embodiments, the caster moves between its locked and unlocked configurations in response to rotation of a rotatable cam. Other embodiments provide a wheel lock assembly including a rotatable track wall, which comprises a generally cylindrical wall configured to rotate about a second axis. In such embodiments, the caster is configured such that the rotatable track wall rotates about the second axis when the caster moves between locked and unlocked configurations.

    摘要： The present disclosure is an eccentric jounce travelling mechanism for a children's toy vehicle and a travelling method. The mechanism includes a vehicle frame, and a front wheel component and a rear wheel component arranged at a bottom of the vehicle frame for supporting the vehicle frame, and an eccentric adjustment mechanism is arranged at an interior of the front wheel component. By arranging the eccentric adjustment mechanism, the position of a positioning shaft can be controlled, and whether the front wheel component is eccentrically mounted or not can be controlled by the relative position between flat grooves on the positioning shaft and limit blocks, to cause the children's toy vehicle to smoothly travel and jounce upwards and downwards, increasing the interestingness of the children's toy vehicle.
