Picking mechanism with metamorphic function, Bending apparatus for material testing and micro-ct imaging, mechanical arm with synchronous belt transmission device, Suitable for the lifting mechanism of disk-like accessory, STRIP CUTTING SYSTEM BY HELICOIDAL KNIVES AND CORRESPONDING CUTTING PROCESS, Improvements in or relating to overhead electric traction systems, Robot arm for use with injection moulding machine, Joint structure of arm, etc. The device may include a pivoting drive source for driving the pivots of the main arm member and the sub arm member centering on the pivoting axis. Therefore, compared to the case of coupling the units in an order different from above, the pivoting unit positioned at the farthest tip end can perform the postural displacement in a different range. 38. wherein the device comprises a pivoting drive source for driving the pivots of the main arm member and the sub arm member centering on the pivoting axis. Moreover, in the present invention, the gripping unit is attached to the tip end side of the pivoting unit. A Scott Russell linkage is a linkage which translates linear motion through a right angle. A pivoting axis of the pivot of the joint unit may be in parallel to an axis of the pivots of the main arm member and the sub arm member at the coupling position. Machines as simple as livers, machines such as James Watts steam engine and the industrial robots such as PUMA all are composed of mechanisms whether simple, complex or combination of many simple and complex mechanisms. In the present invention, the rotation unit is coupled to the joint unit. Moreover, with the industrial robot according to Patent Document 1, both of the arm members are rotated (turned) about the screw shaft 21 as a rotation center (turning center), then all of the industrial robot including the screw shaft 21 is turned, and thus a problem arises that a drive torque for the turning increases.

The linkage is named after John Scott Russell (1808-1882), although watchmaker William Freemantle had already patented it in 1803. The device may include a pivoting mechanism unit for automatically pivoting the joint unit cooperating with the angle change by the angle changer, a pivot driving unit for pivoting the joint unit via the pivoting mechanism unit independently from the angle change by the angle changer. 19, 2012, WIPO, 4 pages. These mechanisms are governed by Kinematics the study of geometry and motion. In the present invention, either one of the base end parts of both of the arm members is linearly moved by the rotation of the first ball screw, and the pivots (turnings) of both of the arm members are driven about the virtual straight line connecting the base end parts of both arm members therebetween as the pivoting axis thereof, resulting in only both of the arm members turning. CORROSION 2003 (1) CORROSION 2004 (1) International Petroleum Technology Conference (1) Offshore Technology Conference Asia (1) Publisher. The bridge-type mechanism is one of the most widely used displacement ampliers in micro- scale applications. The SR mechanism in combination with a parallelogram mechanism enables the achievement of a pure translation of the gripper tips, which is attractive for practical micromanipulation and microassembly applications.

Classified in two types: 1- Exact straight line mechanisms:- Paucellier mechanism, Hart mechanism, Scott-Russel mechanism, Kempe mechanism,etc. Therefore, a plurality of variations can be provided to the method of moving the base end part of both of the arm members, resulting in being able to flexibly perform the moving of the tip end part of the main arm member. [1] . Furthermore, in the Scott Russell mechanism device according to the present invention, a rotation unit having a rotor may be coupled to the joint unit. Until recently, Jasen Russell tendre la recherche. With the industrial robot according to Patent Document 1, a main arm member (the first arm 31 in Patent Document 1) and a sub arm member (the second arm 32 in Patent Document 1) have fixed thicknesses to secure a desired rigidity (have fixed width and thickness dimensions in cross-sections orthogonal to longitudinal directions of both of the arm members), and thus, as base end parts of both of the arm members (end parts on the screw shaft 21 side in Patent Document 1) are spaced from each other, the arm members interfere with each other at a coupling position of both of the arm members, and a problem arises that the tip end part of the main arm member (end part on the side where the holder H is provided in Patent Document 1) cannot be moved proximally to the sub arm member (a problem arises that the holder H is hard to be moved close at hand to the screw shaft 21 side). wherein either one of the base end part of the sub arm member or the base end part of the main arm member is pivotably coupled to the second linearly-moving unit about the virtual straight line as the pivoting axis thereof.

A pivoting unit having a pivoting part that is pivotable centering on an axis in parallel to the pivoting axis of the joint unit may be coupled to the rotor of the rotation unit. There are many mechanisms based on slider crank linkage which can generate exact straight lines for limited intervals. Further, in the Scott Russell mechanism device according to the present invention, a gripping unit may be attached to a tip end side of the pivoting unit. The main arm member is formed into a boomerang-like shape such that the coupling position is curved to detour to an opposite side from the side where the sub arm member is positioned. 11862054.1, Mar. 10. One of the ends is then connected to something that can generate linear motion, such as a rolling or sliding connection, or another straight line mechanism. Furthermore, in the Scott Russell mechanism device according to the present invention, the angle changer may also have a second ball screw arranged in parallel to the first ball screw, and a second linearly-moving unit for being linearly moved by a rotation of the second ball screw.
