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 so as to turn only both of the arm members. Moreover, in the Scott Russell mechanism device according to the present invention, a pivoting member may be pivotably coupled to the joint unit. 15, 2011, WIPO, 4 pages. Furthermore, Patent Document 4 discloses a Scott . 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. Therefore, the rotation unit attached to the joint unit via the pivoting member can displace its rotor independently of the amount of the displacement of the tip end part of the main arm member, and the postural displacement of the rotor positioned at the farthest tip end increases much more. Scott Russell Business Consultant Santa Barbara, California, United States 2K followers 500+ connections Join to connect Proactivate Consulting LLC About A Senior Business Executive with a. Therefore, by the rotor of the rotation unit where the amount of the postural displacement is increased compared to the conventional device, the Scott Russell mechanism device according to the present invention can be applied to the application of performing the gripping while flexibly responding to the orientation of a workpiece as a gripping target. IPTC (1) NACE (2) OTC (1) Date. Further, in the Scott Russell mechanism device according to the present invention, a gripping unit may be attached to the rotor of the rotation unit. In the present invention, the shape of the main arm member is a boomerang-like shape. Therefore, the application of the Scott Russell mechanism device according to the present invention expands. Therefore, even if the main arm member and the sub arm member are not arranged to offset from each other, when the coupling angle is changed so that the base end parts of both of the arm members are separated from each other, interference between the arm members at the coupling position of both of the arm members is subsided, and the tip end part of the main arm member is easily drawn close to the sub arm member. Freemantle straight-line linkage from British Patent 2741, November 17, 1803. Note that, the substantially parallel angle means that it does not require an accurate parallelism with respect to the sub arm member but includes a slight angle variation, and in the present invention, the substantially parallel angle can be said to be parallel as long as it is within a range of 10 with respect to the axis of the sub arm member in the longitude direction (also in other parts of description a variation range of 10 with respect to the accurate parallelism is included in the meaning of the phrase substantially parallel). In the present invention, the joint unit, the rotation unit, and the pivoting unit are coupled to each other in this order. [1][2], A different form of the linkage has been used in a front-wheel-drive vehicle with solid rear axle to control lateral movement, and with a flexing elastomeric connection instead of the rolling or sliding connection. The flexure-based Scott-Russell mechanism can be simplified as four bar mechanism and shown in Fig. Therefore, the gripping unit can be pivoted proximally to the workpiece which is the gripping target, and the Scott Russell mechanism device including a griping function suitable for such a gripping application can be provided. A rotation unit having a rotor may be coupled to the pivoting member.

Further, when both of the base end parts of both of the arm members are moved in the same direction by the same amount, both of the arm members can be moved entirely while keeping their postures. The Scott Russell mechanism device of, 16. a sub arm member pivotably coupled to the main arm member; and. Stuart J. Russell and Peter Norvig Upper Saddle River, New Jersey 07458. 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). Thus, when the coupling angle is changed so that a base end part of the main arm member and a base end part of the sub arm member are most separated from each other, a tip end . Therefore, by the rotor of the rotation unit where the amount of the postural displacement is increased compared to the conventional device, the Scott Russell mechanism device according to the present invention can be applied to the application of performing the gripping while flexibly responding to the orientation of a workpiece as a gripping target. Therefore, the gripping unit can be pivoted proximally to the workpiece which is the gripping target, and the Scott Russell mechanism device including a griping function suitable for such a gripping application can be provided. Highlight matches. These mechanisms are simple linkage mechanisms with revolute joints, but they can only generate approximate straight lines and that too only for short lengths. 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. Scott-Russell Exact Straight Line Mechanism: Scott-Russell The complexity of the mechanisms to generate exact straight lines can be reduced by introduction of one or more slider crank linkages. Moreover, in the Scott Russell mechanism device according to the present invention, the sub arm member may be linearly formed. The Scott Russell mechanism device of, 19. In the present invention, the joint unit, the rotation unit, and the pivoting unit are coupled to each other in this order. 10, 2015, Germany, 6 pages. The Evans 'grasshopper' linkage is a variant of a Scott Russell linkage which uses a long link to create a large enough arc to approximate a line. 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. In the present invention, when the coupling angle is changed so that the base end parts of the main arm member and the sub arm member are most separated from each other, the degree of the curve of the main arm member is defined such that the second section of the main arm member is in a substantially parallel orientation to the linear sub arm member. Moreover, by providing a pivot driving unit to the main arm member, as well as providing a fourth motor and a drive transmission mechanism unit to the sub arm member, the Scott Russell mechanism device can switch between pivoting the joint unit associatively a change of a coupling angle of the arm members and and pivoting the joint unit by the drive of the fourth motor. Scott Russell's Mechanism - Special Mechanism - Kinematics of Machinery Ekeeda 914K subscribers Subscribe 44 2.1K views 7 months ago Subject - Kinematics of Machinery Video Name - Scott. The use of flexure joints in the Scott Russell mechanism provides a number of advantages over traditional revolute joints, making it a valuable technology for use in space where maintenance is difficult and costly. In the present invention, the rotation unit is coupled to the joint unit. 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. wherein the device comprises a pivot driving unit provided at any portion from the coupling position toward the tip end side of the main arm member and for pivoting the joint unit.
