    摘要： A safety operation system for a manipulator is provided with a first operation section. The first operation section has a first movable section, and outputs a first operation signal representing the position and angle of the first movable section. A failure detecting section detects failure of the first operation section on the basis of the first operation signal, and outputs a detection signal. When failure of the first operation section is not detected, a conversion section converts the first operation signal into a control signal. A second operation section has a second movable section which moves in accordance with movement of the first movable section, and outputs a second operation signal generated in accordance with movement of the second movable section. A comparison section compares the control signal with the second operation signal, and outputs a deviation signal used for opening the second movable section. A management section receives the detection signal, and supplies the comparison section with a signal for making deviation signal zero, thereby prohibiting the second movable section from being driven. A display section displays data on the failure of the first operation section and/or data on the current position of the first movable section, on the basis of a signal output from the management section.

    摘要： After positional information of the master arm is transformed into first generalized world coordinates corresponding to positional information representing a calculated position of the slave arm, when a signal instructing an interruption of the associated operation between the master arm and the slave arm is received and then the positional relationships between the master arm and the slave arm connected thereto by use of an imaging device are updated, the first generalized world coordinates are transformed into the second generalized world coordinates based on the new positional relationships so as to restart the associated operation therebetween. The optimal control of the manipulator is conducted through matrix operations related to the change-over between imaging devices, the reset operation conducted in an area of the movable range of the master arm, and the alteration of the ratio between the movements of the associated operation.

    摘要： A safety system and method for industrial robots includes a detection arrangement having a detection field covering the area of reach or operation of the robot. Detection data obtained through the detecting arrangement in each of predetermined operation positions of the robot is compared with the detection data indicative of the normal or correct detection field in the same operation position. The movement of the robot to the next operation position is prohibited when a difference of a level exceeding a predetermined level is obtained during the comparison.

    摘要： A fluid pressure actuator having a first member, a second member adapted to rotate relative to the first member, and a third member adapted to move on the second member. One of the first member and the second member is formed thereon with two flanges disposed in spaced-apart relationship for closing opposite ends of a first pressure chamber defined between the first and second members. The flanges are each formed in the outer periphery thereof with a groove communicating with passages formed in the first and second members for supplying therethrough power for moving the third member. The actuator is small in volume, dispenses with piping located outside the actuator, and is easy to provide a fluid seal thereto.

    摘要： A master slave manipulator system includes a master arm having six or more axes of motion and an articulated slave arm having six or more axes of motion and being shaped in sharp contrast with the master arm. The master arm has an arm body with three axes perpendicular to each other and a wrist assembly connected to the arm body. The wrist assembly has a gripper disposed in a space of a size large enough for an operator to operate the gripper with his clutched hand in X, Y and Z directions and also has a pitch-axis, a yaw-axis and a roll-axis all disposed outside of the space. The pitch-axis, yaw-axis and roll-axis have output axes directed toward the gripper. The slave arm has an arm body with axes longitudinally stretchable or foldable into parallel positions, and a wrist assembly having three axes disposed in a space of predetermined dimensions in X, Y and Z directions. The output axes of the three axes of the slave arm wrist assembly are directed away from the mounting portions of these axes. The slave arm is so controlled as to follow movements of the master arm.

    摘要： In this manipulator system, a small arm is coupled with an arm portion of a large arm excepting the tip, and the large arm and the small arm are independently controlled to operate. For coupling the small arm with the arm portion of the large arm, a capturing mechanism located at the tip of the large arm is actuated to be coupled with a capturing mechanism of the small arm. Another capturing mechanism of the small arm is moved to a capturing mechanism located on the arm portion of the large arm to be mechanically and electrically coupled therewith. When this coupling has been completed, the coupling between the capturing mechanism located on the tip of the large arm and the capturing mechanism of the small arm is released. As a result, the small arm can be branch-connected to the large arm, and expansion of the work range and complex work become possible.
