Joystick for controlling displacement and displacement rate of moving object in professional machine e.g. crane, has sensor transmitting control signal of movable object to connector based on speed of rotation of wheel

摘要

The joystick (10) has a handle (11) connected to a base (12) and moved relative to a plane (XY) through a ball joint. Two wheels (21, 22) are rotated around two different rotation axes. A sensor (31) transmits a control signal (S2) of a movable object (80) to a connector (14) based on an angle and the speed of rotation of one of the wheels relative to an initial position. Another sensor (32) transmits another control signal (S3) of the movable object to the connector based on the angle and the speed of rotation of the other wheel relative to another initial position. An independent claim is also included for a system including a computer and a joystick.
