However, some minor adjustments to the code and testing on an amputee are still required before its complete. The overall price tag comes in under $100, utilizing two servos (one for the thumb and one for the four other fingers) controlled by a Myoware muscle sensor. I opted for more powerful servos to enhance strength, but standard servos can be used as well. The materials needed are: Servo - http://www.banggood.com/JX-PDI-6221MG-20KG-Large-Torque-Digital-Coreless-Servo-For-RC-Model-p-973947.html Battery - https://www.pololu.com/product/2224 Flexible Nylon Paracord to pull finger back - http://www.paracordplanet.com/black-1-8-shock-cord/?gclid=CjwKEAjwoPG8BRCSi5uu6d6N5WcSJABHzD8F0L0fHDhT_dqwNNAAP0UubP1OmgCBMNTkp_OyXJ0xuBoC05Tw_wcB Arduino Nano - http://www.banggood.com/NANO-IO-Shield-Expansion-Board-Nano-V3-Improved-Version-With-Cable-For-Arduino-p-1010993.html Rubber Sheet - http://www.ebay.com/itm/NEOPRENE-RUBBER-SHEET-1-32-THK-X-36-x12-WIDE-60-DURO-5-/252444357962?hash=item3ac6db354a:m:mfM4gXGbn2nDErOINfWRrrQ Fishing wire - can be sourced from anywhere. A video tutorial on assembling the arm will be posted soon, as it is a relatively straightforward process. However, there are some tips and tricks that can make the assembly easier and improve performance.
