摘要:
A control method for a stair climber (1) comprising at least one support frame (4), a motorised mechanical group (6) stably coupled to the frame (4), at least one stabilising element (8) operatively coupled to the frame (4), at least one first sensor (11) operatively coupled to the frame (4) and arranged so as to detect at least the presence of steps during the descent process (102) and at least one processing and control logic unit operatively connected with the first sensor (11), with the stabilising element (8) and with the mechanical group (6). This method comprises a descent process (102) having at least the following phases: a first phase (103) in which the logic unit commands the group (6) so that the climber (1) advances until the first sensor (11) detects the presence of a first step; a second phase (105) in which the logic unit stops the group (6) interrupting the advancement of the climber (1); a third phase (108) in which the logic unit commands the extraction of the stabilising element (8) so as to arrange it according to an operating configuration; a fourth phase (109) in which the logic unit commands the group (6) so that the climber (1) advances until the first sensor (11) detects the presence of a second step; a fifth phase (110) in which the logic unit commands the retraction of the stabilising element (8) so as to arrange it according to a rest configuration; a sixth phase (112) in which the logic unit commands the group (6) so that the climber (1) advances along the descent.
摘要:
The present invention provides a movable vehicle. The movable vehicle comprises a carrying mechanism and a holding mechanism connected to the carrying mechanism, and the bottom of the carrying mechanism is provided with wheels, wherein the movable vehicle further comprises a starting mechanism arranged on the holding mechanism, the starting mechanism comprising a starting unit, a power supply unit, and a controller. The starting unit is configured to be switchable between an initial position and a start position. The controller is configured to be electrically connectable to the power supply unit, wherein when the starting unit is in the start position, the starting unit is coupled to the controller to activate the electrical connection between the controller and the power supply unit, and when the starting unit is in the initial position, the starting unit is decoupled from the controller. According to the above solution, a user can easily activate the electrical connection between the controller and the power supply unit simply by operating the starting unit on the holding mechanism, thereby allowing the controller to further perform various control operations.

An omnidirectional cart including a cart part including a plurality of driving wheels, a body part attached to the cart part rotatably around a pivot axis, a command generation unit that generates a speed command indicating a translational speed and a rotational speed of the body part at predetermined cycles, and a control unit that searches for a predetermined number of the speed commands for maintaining the direction of the translational speed indicated by the speed command of a current step and calculates a speed command whose excess rate is less or equal to a threshold or whose excess rate is minimum among the predetermined number of the speed commands, the excess rate indicating how much values of torque and angular speeds of driven wheels and the pivot axis exceed axes limitation values when the omnidirectional cart operates in accordance with the speed command of the current step.
摘要:
An assisted propulsion system, method and chassis for conveying a payload along a surface are described. A plurality of wheels disposed about the chassis support it on the surface. A drive provides at least assisted propulsion to the chassis along the surface. At least a driving part of the drive is connected to the chassis via a mount having a resiliently sprung link. At least the driving part of the drive has a fixed orientation and is moveable independently of the chassis and the plurality of wheels in a direction towards the surface. The resiliently sprung link is arranged to direct at least the driving part onto the surface during provision of the assisted propulsion. A sensor is arranged to monitor acceleration of the drive and to communicate data on acceleration to a controller, which controls operation of the drive in dependence on the data received from the sensor.

A lift truck includes systems and methods for improved stability control. Stability control features reduce or eliminate motion of the truck in one or more of the X-axis, Y-axis, and Z-axis. Some embodiments may include, alone or in combination with the stability control, vibration control to further stabilize the motion of the truck.

The tiller-steered industrial truck (10) has a drawbar (18) which is provided with an arm (20) and a head (22). The rotary motion sensors (24,28) arranged in the drawbar, detect the movements (A,B) of the drawbar along the axes (26,30) respectively. An evaluation module forwards a control signal generated for the operation control of vehicle when the detected movement of the drawbar exceeds a predetermined value.
