A Scott Russell linkage (for John Scott Russell (1808–1882), although already patented in 1803 by watchmaker William Freemantle[1][2]) gives a theoretically linear motion by using a linkage form with three portions of the links all equal, and a rolling or sliding connection. It can be used to form a right-angle change of motion, linear-to-linear.
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.[3]

The linkage does not share the disadvantages of the asymmetric Panhard rod and although more compact than Watt's linkage has all the forces in one link.[4]
