To date link mechanisms are often used successfully in mechanisms to transmit forces or guide points and planes.
They enable to appropriate many motion tasks like oscillations, vibrations, linear guide and step- and dwell
motions in a simple and certain way. Because of the diverse application possibilities of link mechanisms our
fields of activity in the research are subdivided by them.
