The Chebyshev Lambda Linkage is more commonly referred to as a Four-Bar Linkage. It converts rotational motion to linear motion while keeping a constant velocity. It has two fixed joints, one small driving link and three bigger mobile links. [11]
It is used commonly in suspension mechanisms, walking robots and rover wheel mechanisms. [10]
This mechanism is very commonly used in undergraduate engineering courses, specifically mechanical engineering. At Ohio University, you will learn about this mechanism with Dr. Bob in his Kinematics course.
