    Abstract: A compact, lightweight manipulation system that excels in operability and has a force feedback capability is provided. When automatic operation of a slave manipulator 105 that follows manual operation of a master manipulator 101 is bilaterally controlled by means of communication, the force acting on the slave manipulator is fed back to the master manipulator by operating the master manipulator primarily under electrically-driven speed control and the slave manipulator primarily under pneumatically-driven force control. Therefore, in the master manipulator, it is not necessary to compensate for the dynamics and the self-weight of the master manipulator in the motion range of a user, allowing highly accurate, broadband positional control, which is specific to an electrically-driven system, and in the slave manipulator, nonlinearity characteristics specific to a pneumatically-driven system presents passive softness, provides a high mass-to-output ratio, and produces a large force.

  • Patent number: 7744327
    Abstract: The invention relates to a tubular handling apparatus for moving tubulars between a substantially horizontal transfer station and a second transfer station. The apparatus comprises a base and a boom, rotatable with respect to the base between a lowered position and a raised position by boom rotation drive means in a boom rotation direction around a horizontal boom rotation axis. Furthermore, the apparatus comprises a gripper, rotatably attached to the boom and adapted for gripping the tubular, which gripper is rotatable about a gripper rotation axis by a gripper rotation drive means in a gripper rotation direction. According to the invention, the gripper rotation axis is parallel to and spaced from the horizontal boom rotation axis and in that the gripper rotation drive means provide a gripper rotation direction opposite to the boom rotation direction.

  • Publication number: 20090182436
    Abstract: A robot arm formed from one or more optionally interlinked active pivoted levers, wherein a base is fixed to the one end of a support and a pivoting piece is pivotably mounted on the second end of the support with pneumatic muscles running form the base to the pivoting piece. Individual pneumatic muscles engage on opposing sides of the pivot axis of the pivoting piece and the base of a pivoting lever is fixed to the pivoting piece of the adjacent pivoting lever interconnected thereto. The controller measures the position of the individual pivoting levers and the pressure in the individual pneumatic muscles, calculates the externally acting forces from the pressure-distance diagrams for the individual pneumatic muscles and the geometric lever mechanical ratios for all pivoting levers and limits said forces.

The robot has a control configuration having a hierarchical structure including a higher order central calculation section corresponding to the brain, reflex system control sections corresponding to the vertebra, and servo control systems and actuators corresponding to the muscles. From restrictions to the power consumption and so forth, there is a limitation to increase of the speed of a control cycle of the higher order central calculation section. External force acting upon the machine body is a disturbance input of a high frequency band, and a very high speed control system is required.
