摘要： A hydraulic actuator is disclosed having a cylinder with a piston that is moved by hydraulic fluid. A light guide in one end of the cylinder directs a laser beam into the cylinder, and off the piston where the beam is reflected. The beam then exits the cylinder through a second light guide. A control unit measures the time of flight of the laser beam and calculates the piston position.

摘要： A system for controlling the operation of a tele-operated machine uses a sensor which senses the angular orientation of the joint, converts the angular orientation to a required length of the linear actuator (piston and cylinder) to obtain the then current length. A controller inputs the desired position of the joint and the system defines the length of (or flow to) the linear actuator necessary for the joint to be in the desired position based on a comparison of the desired and actual lengths of the actuator and sets the length of (or flow to) the actuator based on the required length (or flow) necessary to move the joint into the desired position i.e. to extend the length of the actuator to that required for the desired movement of the joint. Alternatively the actual and desired positions may be compared in a comparer (subtracter or adder) and the resultant signal modified based on a function of the actual position and the equipment being controlled and the modified signal is used to define the required length of or flow to the actuator.

摘要： A method and apparatus for controlling the movement of an end point of an articulated arm in the x, y and z directions using a manually operated resolved motion control by controlling the component of velocity of the end point in each of the x, y and z directions to change by the same amount for a given change in the component of displacement of the manual controller in the respective x, y and z directions provided the total displacement in the selected x, y or z direction is less than a preselected displacement in the respective x, y or z direction and the end point is within a preselected work space. The velocity of the end point in any one of the x, y and z directions when the total displacement of the manual controller in the respective x, y or z direction is greater than the preselected displacement changes at a ratio of end point speed to change in the component of controller displacement that is independent of the ratio of controller displacement to end point speed in at least one of the other of the x, y or z directions.
