Patent Document 1 discloses a Scott Russell mechanism applied to an industrial robot. 38. 10, 2015, Germany, 6 pages. Jasen Russell sur LinkedIn : The mystery of what's eating our plastic a pivot driving unit for pivoting the joint unit via the pivoting mechanism unit independently from the angle change by the angle changer. If both ends are turned into sliding connections, you get a Trammel of Archimedes. Further, in the present invention, the gripping unit is attached to the rotor of the rotation unit. The linkage is named after John Scott Russell (1808-1882), although watchmaker William Freemantle had already patented it in 1803. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO). It is a four bar mechanism and all the pairs are turning pairs as shown in Fig. In the present invention, the rotation unit is coupled to the joint unit. With the industrial robot according to Patent Document 1, both of the arm members are rotated (turned) about the screw shaft. A mechanical linkage is an assembly of systems connected to manage forces and movement. Therefore, the rotation unit attached to the joint unit via the pivoting member can displace its rotor independently of the displacement of the tip end part of the main arm member. The angle changer may have a first ball screw arranged in parallel to the virtual straight line, and a first linearly-moving unit for being linearly moved by a rotation of the first ball screw. 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, and.
