Spain-based creator Ivan Miranda used a 3D printer to build a gigantic robotic hand that will eventually be a part of a much larger project. This isn’t a basic animatronic hand, but rather one with fifteen individual motors, enabling it to fully articulate as well as grip objects.
You won’t be able to 3D print this at home either, as Miranda hand built the large-format 3D printers you see fabricating this gigantic robotic hand. Once all of the parts were printed, servo motors were added to acutate each joint, while an Arduino Mega board controls them with pulse-width modulation. Most of the servos generate around 11kg-cm of torque, but the ones found in the palm at the base of each finger produce 25kg-cm for extra gripping strength.

This is definitely the first iteration of this 3D printed robotic hand as once finished I got lots of ideas that will make it 10 times better and honestly, does one ever finish building his giant rideable robot?,” said Miranda.
