    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: The present invention applies to carts (1) in which the driver is not carried on, and which have a single forward direction (FWD) and a single center of rotation at standstill (RCV0), and discloses a pivoting handlebar (12) at the rear of the cart (1) which can move freely to both sides, preventing the driver from having to move laterally during turns.
    Discloses also an articulated vehicle (0) comprising a combination of a cart (1) provided with a pivoting handlebar (12) and a rear driven element (20) carrying the driver; and both main elements are connected by means of an articulated structure (21) which is hinged around the cart (1). The pivoting handlebar (12) improves maneuverability and stability, since it prevents the driver from seeking lateral support on the handlebar, eliminating the vehicle's oversteering effect (0) that such support would entail.

    摘要: A working machine includes a machine body, a left traveling device located left on the machine body, a right traveling device located right on the machine body, and a controller configured or programmed to perform automatic deceleration to automatically reduce a first rotation speed of a left traveling motor and a second rotation speed of a right traveling motor by shifting a speed stage of each of the left and right traveling motors from a second speed stage to a first speed stage that is lower than the second speed stage. The controller is configured or programmed to: not perform the automatic deceleration when the first rotation speed or the second rotation speed is equal to or higher than a predetermined rotation speed; and perform the automatic deceleration when the first rotation speed and the second rotation speed are less than the predetermined rotation speed.

    摘要: A working machine includes a controller to perform automatic deceleration to automatically reduce a first rotation speed of a left traveling motor to output a power to a left traveling device on a left portion of a machine body and a second rotation speed of a right traveling motor to output a power to a right traveling device on a right portion of the machine body by shifting a speed stage of each of the left and right traveling motors from a second speed to a first speed that is lower than the second speed. The controller is configured or programmed to determine, based on the second rotation speed, a left threshold for judging whether to perform the automatic deceleration in left pivot turn of the machine body, and to determine, based on the first rotation speed, a right threshold for judging whether to perform the automatic deceleration in right pivot turn of the machine body.

    摘要: A guided vehicle includes: a first wheel section positioned at a front end portion of a base; and second and third wheel sections which are independent from each other. The first wheel section includes a left-right frame body, and swivel wheels arranged on left and right portions of the left-right frame body. An intermediate position between the swivel wheels in the left-right frame body is supported to be swingable about a front-rear axis relative to the base. Each of the second wheel section and the third wheel section includes a front-rear frame body, and a driving wheel and a swivel wheel which are respectively arranged at a front portion and a rear portion of the front-rear frame body. An intermediate position between the driving wheel and the swivel wheel of each front-rear frame body is supported to be swingable about the left-right axis and the front-rear axis relative to the base.
