Mechanical Tentacle
thingiverse
My current project involves creating a tentacle controlled by mind. At present, the ball and socket joints are too loose, causing poor movement due to part weight and stiffness in PLA-printed sockets. Post these issues' resolution, I will connect servos and an Arduino for operation. A video showcasing this functionality can be viewed at http://youtu.be/EVMatHNgC6s. For assembly, print one end and as many segments required, remove support from segments, and string a minimum of three cords through the holes.
