Summary of Creator Uses 3D Printer to Build a Gigantic Robotic Hand
Spain-based creator Ivan Miranda used large-format 3D printers he built to fabricate a gigantic robotic hand featuring fifteen individually motorized joints. After printing the parts, he fitted servo motors to actuate each joint and used an Arduino Mega to control them via pulse-width modulation. Most servos produce about 11 kg-cm torque, while palm-mounted servos at each finger base provide 25 kg-cm for stronger grip. The hand is intended to become part of a larger project.
Parts used in the Gigantic Robotic Hand:
- Large-format 3D printers (custom-built by Ivan Miranda)
- 3D printed hand parts (fingers, palm, joints, structural components)
- Servo motors (fifteen total; most ~11 kg-cm torque)
- High-torque servo motors for palm bases (25 kg-cm torque)
- Arduino Mega board
- Wiring and connectors for servos and Arduino
- Fasteners and assembly hardware (screws, bolts, etc.)
- Power supply for servos and electronics
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.
- Who built the gigantic robotic hand?
Spain-based creator Ivan Miranda built the robotic hand. - How were the parts for the hand produced?
The parts were produced using large-format 3D printers that Miranda built himself. - How many motors does the robotic hand use?
The hand uses fifteen individual servo motors to actuate the joints. - What controls the servos in the robotic hand?
An Arduino Mega board controls the servos via pulse-width modulation. - What torque do the servos provide?
Most servos generate around 11 kg-cm of torque, while the palm-mounted servos produce 25 kg-cm. - Are the 3D printers used commercially available?
No, Miranda hand built the large-format 3D printers used to fabricate the hand. - Is this hand a standalone project?
The hand will eventually be part of a much larger project.
