Check out my 2nd channel, TT Racing: @ttracingYT Building on my previous breakdown of over centre and cam mechanisms, in this video we explore four bar linkages. This is another versatile mechanism that can be configured in numerous ways. In this video, I design and 3d print a modular version so these configurations can be tested and demonstrated. We explore scenarios for introducing motors and servos too. Source CAD for this video: 0:00 Introduction Previous video on over centre mechanisms: 0:44 Where do we find four bar linkage mechanisms?
