Scott Russel | eMachineShop However, a bridge-type mechanism with an external load always works in an energy-inefcient situation due to the storage of strain energy in the exural hinges, which can be validated by the analytical model established in this paper. New Structural Design of a Compliant Gripper Based on the Scott-Russell 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. Furthermore, Patent Document 4 discloses a Scott Russell mechanism applied to an industrial robot. SQUSE INC., JAPAN, Free format text: An axis of the pivot of the pivoting member may be in parallel to the pivoting axis of the joint unit. 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. Book - NIPS Learn CAD with SolidWorks 2008- Create new sketch tutorial by John Sinitsky, Creating new file in CAD program - Overview of SolidWorks2008 Menu by John Sinitsky. A Scott Russell linkage is a linkage which translates linear motion through a right angle. wherein the main arm member is formed linearly in a first section extending from the base end part to the part corresponding to the coupling position and in a second section extending from the part corresponding to the coupling position to the tip end part, and the part corresponding to the coupling position is curved, and. Note that, a direction of the X-axis illustrated in, About the above-described angle on the coupling position, When the coupling angle between the main arm member, In a case where the main and sub arm members, Therefore, for example, when the second motor M, Note that, in a case where the change of increasing the coupling angle is desired to be performed quickly, the rotations of the first and second motors M, Note that, the rotations of the first and second motors M, Note that, the Scott Russell mechanism device, Moreover, in a case where it is desired to point the gripping unit, Further, regarding the mechanism for pivoting the joint unit, Moreover, with the configuration as described above, it is suitable for the fourth motor M, Moreover, other than the application of gripping, for example, in a case of applying to the application of placing and moving the workpieces, a placing unit or the like is attached instead of the gripping unit, That is, the Scott Russell mechanism device, As for the Scott Russell mechanism device, Note that, also as for the Scott Russell mechanism device, Therefore, also in the third embodiment, similarly to the first embodiment, if the control on the fourth motor by a motor controller (corresponding to a switch means) provided accompanying the Scott Russell mechanism device, According to the configuration above, also as for the Scott Russell mechanism device. Therefore, as for the application of the Scott Russell mechanism device according to the present invention, the posture of the joint unit can be changed in the total of two kinds of manners. In the present invention, the shape of the main arm member is a boomerang-like shape. The main arm member and the sub arm member may be pivotable about the virtual straight line as a pivoting axis thereof. The Scott Russell mechanism device of, 16. The Scott-Russell mechanism gives a theoretically linear motion by using a linkage form with three portions of the links all equal, and a rolling or sliding connection. The SR mechanism in combination with a parallelogram mechanism enables. Robotics and Computer-Integrated Manufacturing Specifically, the tip end part of the main arm member can be moved by only moving the base end part of the main arm member, by only moving the base end part of the sub arm member, or by moving both of the base end parts of both of the arm members, respectively. Moreover, Patent Document 3 discloses a Scott Russell mechanism applied to a drive structure of a feed arm. Exact Straight Line Mechanisms - Peaucellier linkage and Scott-Russell Grasshopper Mechanism: This mechanism is a modification of the Scott-Russell Mechanism. 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. A standard Scott Russell straight- mechanism was invented by a French army officer, line mechanism provides an exact straight-line mo- Charles Nicolas Peaucellier, in 1864. 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. New Structural Design of a Compliant Gripper Based on the Scott-Russell Either one of the base end part of the main arm member or the base end part of the sub arm member may be pivotably coupled to the first linearly-moving unit about the virtual straight line as the pivoting axis thereof. wherein an axis of the pivot of the pivoting member is in parallel to the pivoting axis of the joint unit, and.

Scott Russell mechanism developed by John Scott Russell (1808-1882), although already patented in 1803 by watchmaker William Freemantle, gives a theoretically linear motion by using a linkage form with three portions of the links all equal, and a rolling or sliding connection. a pivot driving unit for pivoting the joint unit via the pivoting mechanism unit independently from the angle change by the angle changer. In the present invention, the base end part of either one of the sub arm member or the main arm member is linearly movable by the second ball screw. This paper presents the structural design and analysis of a novel compliant gripper based on the Scott-Russell (SR) mechanism. wherein a base end part of the main arm member and a base end part of the sub arm member that is on the opposite side from the coupling side of the sub arm member are positioned on the same virtual straight line, and a first distance from the base end part of the main arm member to a coupling position of the main arm member to the sub arm member, a second distance from the coupling position of the main arm member to a tip end part thereof, and a third distance from the base end part of the sub arm member to the coupling position are equal to each other.
