3D Printed Powered Exoskeleton Hands (Upgrade v2)

thingiverse

Finally got around to upgrading this powered exoskeleton hand, making it significantly lighter and more mobile. Some design issues persist with this exoskeleton hand in that fingers don't fully extend from a completely closed position to open; instead, they move just slightly. I don't want users to think this can fully restore hand movement as it currently stands. I hope others will take this design further since my modeling skills aren't what they used to be. Good luck with this project - the motors I'm using are not strong enough to break fingers and I believe finding smaller motors that could cause harm would be extremely difficult. DC motor specifications: over 30RPM or 60RPM Mini N20 DC Metal Gear Motor Example: https://www.ebay.com/itm/6-12V-300-600-30RPM-Mini-DC-Metal-Gear-Motor-Gearwheel-Shaft-Diameter-N20-TOP/191977349889?hash=item2cb2bde301:m:mQwibMb0uJEItZMhfW2D6AQ I'm not sure if a 12v DC motor will work with an Arduino, which is why I opted for the 6v motor. You should be able to purchase this from eBay or Amazon. The basic Arduino code is attached and it will open and close all of the motors.
