MotionGen is an iOS and Android app for synthesizing and simulating planar four-bar linkages.
– It solves the motion generation problem for N-position problems.
– Incorporates fixed- and moving-pivot and line constraints for 3 and 4 position problems.
– Use MotionGen to design and simulate single degree of freedom linkages for your robot or machine.

This app needs Android version 5.1 or above to function properly.
