Short description: Linkage generating approximate straight line motion
Animation of the Roberts Linkage

Dimensions:
Green Triangle = a, a, b (a are the longer sides)
Yellow Links = a
Horizontal Distance between Ground Joints = 2b

A Roberts linkage is a four-bar linkage which converts a rotational motion to approximate straight-line motion.[1]

The linkage was developed by Richard Roberts.[1]

The Roberts linkage can be classified as:
