The Robot Head Project - 2 Degree of Freedom Gimbal
I originally saw the mechanism for this project on Youtube. I wanted to create this in a fully 3d printable form because it's an interesting interactive mechanism. I also thought it would make for a fun kinetic sculpture! This video shows the engineering process behind RobBob the robot. In the animation, 1 motor controls the rotation of the head through the yellow shaft and bevel gear. The tilt of the head can be controlled by rotating both motors together. In my mechanical 3d printed version I used knobs instead of motors: You can download the printable STL files from here There is one design flaw, however, where if you only rotate the 'tilt' knob, the head will tilt and...
