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

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

The linkage was developed by Richard Roberts.[1]
The Roberts linkage can be classified as:
- Watt-type linkage[1]
- Grashof rocker-rocker[2]
- Symmetrical four-bar linkage[3]
