Talk to the (low-cost robotic) hand!

Arduino TeamMarch 14th, 2017

Though this low-cost robotic hand by Maker “MertArduino” might not be the best platform for manufacturing, or even world domination, it does show off some interesting physical build techniques. The DIY device can mimic a human’s hand wirelessly via a pair of Arduino Unos and nRF24L01 modules.

For construction, the fingers and thumb are made out of springs and foam, and nylon cords are used to pull them closed with a small servo for each digit. Control is accomplished by flex sensors attached via zip ties to a glove. It’s a great demonstration of how you don’t actually need a 3D printer or other advanced CNC machinery to craft something really unique!

You can see the project in the video below, and check out more hacks on Mert Arduino’s YouTube channel!
