Traveling control method and traveling control device for aerial work platform
Reduction of minimum turning radius of an aerial work platform. Drive motors are provided to driven wheels of the platform respectively, so that the driven wheels can be independently controlled in terms of rotational speed and rotation direction. When the steering angle of steered wheels is at most a first steering angle, constant velocity control is performed, driving both of the driven wheels in the same rotation direction and at the same rotational speed. When the steering angle exceeds the first steering angle and is at most a second steering angle, differential control is performed, reducing the rotational speed of the driven wheel on the inside in the turning direction relative to the driven wheel on the outside in the turning direction. When the steering angle exceeds the second steering angle, counter-rotation control is performed, counter-rotating the driven wheel that is on the inside in the turning direction.
LIFT DEVICE WITH DEPLOYABLE OPERATOR STATION
A lift device includes a lift apparatus and a base assembly. The lift apparatus is configured to raise and lower an implement assembly. The base assembly is configured to support the lift apparatus. The base assembly includes a deployable operator station transitionable between a deployed position and a stowed position. In the deployed position, the deployable operator station is configured to provide a seating and control arrangement for an operator. In the stowed position, the deployable operator station is substantially sealed from an external environment to limit access to the deployable operator station.
Lift mechanism for robotic shuttle system
A robotic shuttle system includes a rack system and one or more shuttles. The rack system includes a rack and a shuttle frame. The rack has storage locations for containers containing items. The shuttle frame has rails disposed along the rack. The shuttle includes a powertrain, container transfer mechanism, and a robot arm. The power train is configured to move the shuttle along the rails of the rack and on a surface outside of the rack system. The container transfer mechanism is configured to transfer the containers between the rack and the shuttle. The robot arm extends from the shuttle to transfer the items between one of the containers on the shuttle and a container in a container holder of the shuttle.
ELEVATION BASED MACHINE LOCALIZATION SYSTEM AND METHOD
A method of determining a relative elevation of a work machine. The method includes receiving a first pressure reading from a first pressure sensor coupled to a chassis of a work machine and receiving a second pressure reading from a second pressure sensor. The method also includes calculating a first relative elevation of the chassis of the work machine relative to the second pressure sensor by comparing the first pressure reading to the second pressure reading.
