Simple Robotic Gripper by Aidan

Aidan often stops by on Adafruit Show & Tell and shares his latest progress on soft robotics. He recently shared his simple robotic gripper using a continuous micro servo and nylon thread that can be used to pick up various objects.

This is a 3D printable soft robotic gripper that functions very similarly to a human’s fingers. It combines rigid and soft materials to articulate in a bending motion.

Keep up the great work Aidan!

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

Join 7,500+ makers on Adafruit’s Discord channels and be part of the community! http://adafru.it/discord

  1. There’s actually a long precedent for this type of multi-material, tendon-driven robot hands. Back in 2009, I took a look at a few of them: http://www.hizook.com/blog/2009/11/15/building-robot-hands-compliant-under-actuated-fingers

    There are some distinct advantages for this type of design (compliance, simplicity, etc), but also some drawbacks (bad pose estimation on fingers, etc).
