Abstract:
An advanced, low cost prosthetic arm was developed for trans-radial amputees based on the need for access to more advanced limbs for those of limited monetary means. The design of the arm was greatly assisted by the current boom in open source technology and hobby level rapid prototyping. The mechanical structure of the arm is entirely 3D printed while the electronics are loosely based on the Arduino Mega. The EMG sensors are replicas of the open source Advancer Technologies EMG kit. The overall manufacturing process was completed through the use of readily available hand tools and a RepRap 3D printer. The total cost of materials for one complete arm is approximately €460 ($640). Currently the arm is controlled via the contraction of either the wrist extensor or flexor. Various grip patterns can be chosen to deal with various situations, giving the hand the greatest flexibility. Current feedback from each finger allows for force limiting and also provides an input for basic mechano-tactile haptic feedback.
