摘要:
The present disclosure relates to a system and method for arbitrating between joystick inputs. The system generates a first command based on the first input if the first input has a non-zero value, and generates a second command based on the second input if the first input has a zero value and the second input has a non-zero value. The system thereby allows two different inputs to control a single commanded function.

In an ophthalmologic apparatus in which a head part is moved at a speed according to a rotation speed of a rotational part of a joystick, in order to enable a moving amount of the head part to correspond to a rotation amount even when the rotation speed becomes higher, the rotation speed of the joystick is detected at predetermined intervals, and when a current rotation speed (count of an encoder during a predetermined period) is lower than a previous rotation speed, a speed obtained by subtracting a predetermined value from the previous rotation speed is compared to the current rotation speed. Then, a higher speed is set as the current rotation speed, and the head part is moved at the speed corresponding to the current rotation speed.

Controlling movement of movable arms on motion shafts of a measurement machine is disclosed. Each motion shaft of the measurement machine are divided into different motion ranges. The movable arms move in different motion ranges at different speeds. Motion direction of the movable arms is associated with an operation direction of a joystick.
摘要:
A control system for a programmable industrial robot has a joystick for manual control of the robot during programming for teaching the robot to follow a working path defined by a number of set points. The control system further comprises a memory for storage of the coordinates of these set points and of other instructions and control members for control of the function of the control system during the programming and for storing or entering instructions in the memory. The control members comprise a group of control members each having a plurality of different functions, the particular function in question being determined by the prevailing condition of the control system. An indicating member is arranged, for each of the control members in the group, to indicate the current function of said control members.

Laser control apparatus for controlling a laser beam with respect to a working area to trace a desired pattern on a working area comprises an input device for inputting the desired pattern; a memory for storing a line pattern; a display for displaying the pattern; and a control system for controlling the laser beam. The control system comprises a Line-Operation selector and an Area-Operation selector, the Line-Operation selector being effective to cause the line pattern stored in the memory to be reproduced by the laser beam on the object, the Area-Operation selector being effective to cause the line pattern stored in the memory to be converted to an area pattern enclosing the area bounded by the line.

For controlling a work process carried out by means of a robot (RB), instructions are stored both relating to the positioning of the robot and relating to the very process to be accomplished. The process instructions are stored in the form of process stage instructions (SPS, SPM and SPE) comprising(a) process start stage, during which the process is initiated (the arc is struck, for instance, when arc welding is involved) and the relative movement between object and robot can be started;(b) process main stage, during which the actual process is carried out; and, at least when the process is not directly followed by a further process;(c) process terminal stage, during which the process is terminated (the arc is broken, for instance, when arc welding is involved) and the relative movement between object and robot can be stopped.A control system for a robot includes memory (PM) for robot instructions, including data for specific process parameters, operating means (OP) for storing robot instructions and means (CU, SS, WC) for automatically carrying out the process controlled by the instructions. The operating means have a control lever (34) with motion in at least two dimensions for controlling said specific parameter data, particularly during execution of a process main stage.

An improved plural axis motion controller (34) is disclosed for controlling servos (14, 16) to move an object (18) such as a flame cutter along a predetermined path. A microcomputer (42) periodically reads the location of the object from position counters (56, 58) and recalculates new velocity control signals for application to the servos in order to cause the object to follow the predetermined path. The improvement is wherein the controller automatically modifies the velocity control signals so as to reduce the spurious velocity variations which the object would otherwise experience due to the nonuniform rate responses of the servos. A table of modifiers, determined during a prior calibration procedure, is stored in a calibration memory (60). The microcomputer selects an appropriate modifier for each velocity control signal in accordance with the direction and magnitude of that control signal and the servo to which it is to be directed.
摘要:
For each degree of freedom of the robot and in the COMMAND mode (switch 32 in position II) the corresponding movable member 21 is moved by an actuator 20 in accordance with an error signal formed as the difference between a command datum C supplied from a register 27 and an actual position datum P supplied by a position sensor 26, the command data required from time to time being provided from a memory 28 via a circuit 34. For training the robot, the FOLLOW mode is selected by putting the switch 32 in position I and the command datum C is replaced by the position datum P, the value of which is periodically entered in the register 27 via a switch 33 which is periodically closed by pulses 35a from a pulse generator 36. When the robot is at a position to which it is to be trained, a switch 30 is closed to write the then contents of the register 27 in the memory 28 for subsequent use in the COMMAND mode.
