These Arduino Wolverine claws are controlled by your muscles

We’ve seen many attempts to recreate Wolverine’s claws, but these 3D printed and Arduino controlled versions, which work off of muscle control, may be the best ones yet.

Initially created at Pixels Camp 2016, the project dubbed “Wolverino” used the littleBits and BITalino platforms. The claws themselves are housed in boxes which sit on top of the wearer’s forearms, and a large, motorised linkage pushes them forwards.

The clever part is a BITalino EMG Sensor which can measure muscle activity. Squeezing your fists will force the claws out, and doing it a second time retracts them.

After taking second at the show, another version of Wolverino was created to use Arduino, in an attempt to create as simpler, lower cost version of the project.

Based on an Arduino Nano, this version uses a force-sensitive resistor in place of the EMG sensor. One of the creators of the project, Hugo Silva, states that this setup is more “temperamental”.

We assume this means that the claws have a tendency to pop out unexpectedly. This is less of a worry when they’re made out of plastic, we reckon.

If you’d like to try your hand at making your own version of this project, you can find a guide over on Instructables.
