Grasshopper straight line mechanism

This mechanism is a modification of the Scott-Russel mechanism showed at: https://youtu.be/rV2l9bcIkMk It is named so because of its resemlance to a grasshopper’s hind leg. Input: pink bar turning +/-40 deg. Point E of green bar traces a vertical nearly straight line (in blue). AB = BC = BE To get the blue line straighter increase DC while keeping the trajectory of point C (in green) as near as possible to the horizontal line. Here AB = BC = BE = 30 DC = 60 Distance AD in vertical direction: 59.8 Distance
