The purpose of the presented invention propose a spring-support mechanism for the parallel robot, and this mechanism is applied to parallel robot models to reduce the load on the actuators. The spring-support mechanism for the parallel robot are composed of: sets of rotated joints to adjust the direction of the support mechanism to match the direction of the moving frame of robot, rhombus mechanism with hinges in four vertices transform displacement of moving frame to elasticity of springs, guiding plates used to adjust the springs length so that the thrust force generated by springs is constant, set of springs is assembled parallel and fixtures for the springs.

The invention relates to the improvement of exoskeletons and masters thereof and to their use in teleoperative applications in virtual worlds or the real world. Non-actuated exoskeletons can be used to transfer loads from the user, for example, heavy luggage, tools or also the body weight of the user, to the ground and to relieve the joint and muscle system of the user. This can increase the endurance and also effective strength of the user. Motor-driven, actuated exoskeletons can be used in different fields. They can be worn as a freely moveable robotic suit which comprises a built-in energy supply and electronic control. They can also be used to improve the force and endurance of a user whilst the user moves in an unlimited environment. Another use of the fixed exoskeleton is in the field of interaction with virtual worlds or for controlling real robots. In this instance, an exoskeleton can be used to establish a teleoperative connection between the user and the master (virtual avatar or real robot). The user users the exoskeleton to directly transfer control commands to the master. The elements of the user and the master then practically carry out the same movements synchronously. The aim of the invention is to improve exoskeletons and masters of the mentioned type and the associated control units. This can, in particular, be achieved by a favorable realization of rotational axes which define rotational movements of different elements which to a large extent perform a hip movement.

The machining station can include a table; at least three robots each having a multi-axis mover secured to the table, and a gripper opposite the table, the robots being interspaced from one another on the table; and a controller. The controller controls the robots to hold a workpiece in a coordinated manner. The computer numerical command (CNC) machine-tool system machines the workpiece while the workpiece is held by the robots. The workpiece can be moved into and out from the machining station with a trolley which slidingly engages a trolley path formed within the table.

A 6-axis positioning system, comprising a base, a movable unit and six variable-length actuators, one end of each actuator being connected to the base and the other end of each actuator being connected to the movable unit. At least one additional variable-length component is provided, one end of which is connected to the base and the other end of which is connected to the movable unit. The 6-axis positioning system can be releasably locked at least in certain positions of the movable unit by means of this additional component. The additional component has a releasable locking brake, and the variable-length component is designed such that its length can be varied passively by means of the movement of the six driven actuators.

Examples of a motion system are disclosed. The motion system comprises a plurality of Stewart platform based actuators connected one to each another forming a desired modular configuration. Each of the plurality of actuators is controlled by a central controller that is configured to independently control the plurality actuators and adjust in real time their position, orientation and motion trajectory. The plurality of actuators are arranged in the desired configuration, shape and size to provide motion system that can mimic a natural motion/gait of human or animal body.

A service satellite having a body, a controller and a docking unit including a telescopic arm, mounted on a 6-DOF parallel manipulator, and two additional gripping arms. The telescopic arm, deployed from the 6-DOF manipulator, is equipped with a pair of rapid closure digits. The telescopic arm facilitates capturing the launch adaptor ring of a client spacecraft, even during tumbling. The 6-DOF parallel manipulator has force sensors and can accommodate post capturing relative motion through active compliance control and controlled de-tumbling, for avoiding generation of high forces in the telescopic arm. After relative rate annihilation, the telescopic arm retracts and the client ring is secured to the 6-DOF manipulator with the help of a pair of clamps. After the ring is secured, two additional gripping arms secure a rigid connection with the launcher ring so that the docking connection comprises three equally spaced connections.

An assembly system for inserting a terminal into a housing comprises a parallel robot mechanism, a serial robot mechanism, and an insertion mechanism. The parallel robot mechanism has a support platform on which the housing is held and a plurality of joints. The serial robot mechanism has an end effector connected to the support platform and is adapted to drive the parallel robot mechanism to move. The insertion mechanism is configured to insert the terminal into the housing. The parallel robot mechanism is moved by the serial robot mechanism to an insertion position in which an insertion hole of the housing is aligned with the terminal prior to the insertion mechanism inserting the terminal into the housing. At least a portion of the plurality of joints are locked while the insertion mechanism inserts the terminal into the housing to keep the parallel robot mechanism and the support platform stationary.

A first and a second fixed shaft seats are rotatably connected to a first and a second rotational support through a hinge, respectively. One end of a first length adjustment device runs through the first rotational support, and the other end is fixedly connected to a moving platform. One end of each of the second and third length adjustment devices runs through the first rotational support and is then connected to the moving platform, respectively. Middle portions of the first, second and third length adjustment devices are each hinged onto the first rotational support. One end of a fourth length adjustment device runs through the second rotational support and is connected to the moving platform. Middle portion of the fourth length adjustment device is hinged onto the second rotational support.
