The Scott Russell mechanism device of. 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. A Scott Russell mechanism device pivotably couples a main arm member and a sub arm member to each other, as well as it pivotably couples a joint unit to a tip end part of the main arm member. Machine Kinematics Question Papers - Sanfoundry 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 part of the main arm member can be moved close to right beside the base end part of the sub arm member. 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. Schematic of a Scott-Russell mechanism using flexure hinges Open in viewer In the present invention, the joint unit pivotably coupled to the tip end part of the main arm member can be pivoted in a total of two kinds of manners including the pivot cooperating with the angle change between both of the arm members at the coupling position and the pivot independent of the angle change. LADDERS, FOOT MECHANISMS FOR LADDERS, AND RELATED METHODS Publication number: 20220381087 The flexure-based Scott-Russell mechanism can be simplified as four bar mechanism and shown in Fig. 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). In the present invention, the gripping unit is attached to the tip end side of the pivoting unit. Conventionally, various kinds of devices using a Scott Russell mechanism exist. A dialindicator is a precision measuring tool that uses a needle or pointer to display a measurement on a dial. The connections between links are modeled as providing ideal movement, pure rotation or sliding for example, and are called joints.
