The code that controls both the prosthesis model and sensing attachments is ready to be used. At this point the code only runs one micro servo as this is a prototype.
All the 3D printed parts - the prosthesis model and the hand tracker - are assambled and modified to house the buttons. The prosthesis is attached to a piece of wood along with the servos that pull the strings attached to the fingertips. Also the potentiometers that sense the positions of the fingers are attached to the sensing glove.
The Arduino Mega attachments are completed on two pieces of prototyping board. On one board, there are the attachments for the 6 servos which control the prosthesis model and the arm attachment. The other board connects to the analog inputs of the arduino to get input from the hand tracker assembly used to control the prosthesis model model.
The 3D printed parts - Thingiverse user embeddedjunkie's "Robotic Hand" model to use as a prosthesis model and some custom parts for hand tracking - are printed out and ready for assembly. These parts will be modified to attach the buttons and a better fit.
Modify the user's choice of prosthesis to house the touch sensors of the buttons on the fingertips.
Assemble the the main elecronics consisting of a microcontroller and the pinout required to attach the servo array and sensors.
Manifacture a comfortable enough servo array to be attached to the user's arm for daily use.
