An apparatus for providing haptic guidance during manipulation of an end-effector includes a robotic arm. The robotic arm has at least one actuated joint, at least one other joint connected to the at least one actuated joint, and a physical constraint movable by actuation of the at least one actuated joint. The physical constraint limits the motion of the at least one other joint in at least one direction. The apparatus further includes an end-effector configured to be manipulated by an application of external forces and connected to the at least one other joint.

A method includes obtaining an implant plan, defining a range of motion for a surgical tool based on the implant plan, adjusting, by an actuator and based on the range of motion, a passive joint coupled between the actuator and the surgical tool, and allowing manual movement of the surgical tool through the range of motion via rotation at the passive joint.

A dual-joint multi-degree-of-freedom mechanical arm and a driving method thereof. The mechanical arm comprises a base, a driving mechanism, a large arm module and a small arm module. The driving mechanism comprises three bidirectional driving components mounted on the base; and the big arm module comprises a big arm push rod, a big arm central rod and an elbow joint universal plate. The comprises a wrist joint universal plate, a universal joint coupler, a small arm central rod, a small arm stretching rod and a wrist joint universal plate. The small arm stretching rod comprises a first connecting rod and a second connecting rod in transmission connection. Two-degree-of-freedom rotation of the big arm module and the small arm module connected in series is independently realized by using three bidirectional driving components fixed on the base, so that movement flexibility of an end executor in a working space is greatly improved.

A parallel link robot includes a base, a movable part, link mechanisms, and actuators. The movable part is movable along a center axis. The first, second and third link mechanisms are provided around the center axis with angular intervals in a circumferential direction around the center axis to project outwardly along a radial direction with respect to the center axis. Each of the first, second and third link mechanisms connects the base and the movable part to move the movable part along the center axis. The angular intervals have an acute angular interval with an acute angle. The first, second and third actuators are provided at the base to be connected to the first, second and third link mechanisms respectively so as to drive the first, second and third link mechanisms respectively.

The present invention includes an apparatus (1) and a method for handling articles and comprises an upper suspension (3) with at least three rotatably driven positioning arms (5), where the positioning arms (5) each comprise at least two arm sections (7, 9) that are swivelable relative to each other and operated independently of one another. A manipulator (32) comprises one or more clamping jaws (34, 36) and is mechanically coupled to the positioning arms (5) such the manipulator can be positioned by movement of one or more of the positioning arms (5). At least one drive shaft (12) is linked non-rotatingly to the manipulator, such that the manipulator is rotated by movement of the at least one drive shaft (12). Rotation of the at least one drive shaft (12) also controls the one or more clamping jaws (34, 36) via the at least one actuating shaft (14).

The present invention is related a redundant parallel positioning table device. More particularly, the present invention relates to a redundant parallel positioning table device for a precise positioning of heavy load samples, instrument and/or apparatus, e.g. in the context of diffractometer machines for synchrotron facilities.

There is provided a robot arm that includes a proximal unit and a distal unit configured to be connected to the proximal unit, the proximal unit having a multiple-connection interface connectable to a plurality of types of distal units different in shape. The connection interface is provided in an end face of the proximal unit with an annular connection interface disposed concentrically.

A joint assembly, a swing device and a robot are provided. The joint assembly includes a movable part defining a movable groove and a rotating part. The rotating part includes a rotating body being a spherical shape. The rotating body is rotatably received in the movable groove to adapt to the movable part. The rotating part defines an air hole with an air inlet and an air outlet. The air inlet is configured to receive introduced air, and the air outlet is configured to expel the air to the movable groove.

A micromanipulator for mounting on the end of a macromanipulator, the micromanipulator comprising: a connection plate with a at least a first and second motor connected to a rigidly mounted base section, a first rotational section connected to the base section about a pivotable axis, the first rotational section being further connected to a slider rod which is connected to the first motor, and a second rotational section connected to the first rotational section about a pivotable axis, the second rotational section being further connected to a slider rod which is connected to the second motor and wherein the rotational joints between the base section and first joint section and the rotational joint between the first and second rotational sections are offset by 90?.
