Error estimation and compensation in 4R and P3R closed-chain mechanisms due to joint clearance: a comparative study [PDF]

Scientific Reports
Four-bar linkages form the fundamental configuration of many planar mechanisms, and joint clearance is one of the primary factors that introduce deviations from their intended output. This paper presents a performance assessment of planar mechanisms with
