A Roberts linkage is a four-bar linkage
In the study of mechanisms, a four-bar linkage, also called a four-bar, is the simplest closed- chain movable linkage. It consists of four bodies, called ''bars'' or ''links'', connected in a loop by four joints. Generally, the joints are configu ...
which converts a rotational motion to approximate straight-line
In geometry, a line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects, though they may exist in two, three, or higher dimension spaces. The word ''line'' may also refer to a line segment ...

The linkage was developed by Richard Roberts.
The Roberts linkage can be classified as:
* Watt-type linkage
* Grashof rocker-rocker
* Symmetrical four-bar linkage
