Design a four-bar linkage that connects the rotation of an input crank to the coordinated rotation of an output crank. Locate the two cranks and define their input and output angles and let MechGen FG design four-bar linkages for you. The design data and an animation of your linkage are easily distributed by email. See the "MechGen FG demo" video on YouTube.

Excellent Job

Very clever for an individual to develop, that works as advertised & the UI is decent. It is not a toy but rather an assist in the design of 4 link mechanisms, where the math can be computed in seconds. Thank You!

Good start

Reminds me of Kinsyn kinematics.
Needs more limitation options like user defined link lengths. Current solutions are too random.
