Title: A compilation of LEGO Technic parts to support learning experiments on linkages,
Abstract: We present a compilation of LEGO Technic parts to provide easy-to-build
constructions of basic planar linkages. Some technical issues and their
possible solutions are discussed. To solve questions on fine details---like
deciding whether the motion is an exactly straight line or not---we refer to
the dynamic mathematics software tool GeoGebra.
