# Kumara-Kampling Inversor Linkage

Input: pink crankshaft

Output: red link performing absolute straight vertical motion. The red link reaches the highest and lowest positions when the blue and green links are in line. The mechanism has an unstable position when the red and cyan links are in line. So, if there is no measure to overcome that position, use only a half displacement range of the red link as shown in the last scenes of the video.

Part lengths: Black link = a Pink link = a Orange link = b + b Green link = c + c Blue link = c + c Cyan link = a Yellow link = b + b Red link = a

b + c must be greater than 2a.
