Roberts linkage explained

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.

The Roberts linkage can be classified as:

• Watt-type linkage
• Grashof rocker-rocker^[2]
• Symmetrical four-bar linkage^[3]
