Conducted by: Luis J. Martinez (Mission, Systems, and Test Engineer) Battery (Duration, Powertrain) As selected from our previous trade-off studies, the battery of choice for powering our Prosthetic Arm, in conjunction with the Prosthetic Hand, recognized as the Upper-Limb Prosthetic System was the 14.8V (4S), 1600–mAh Zippy Compact Lithium-Ion Polymer (LiPo) battery. Incorporated into our […]
Table of Contents Executive Summary Program Objective By Carolina Barrera The objective of the Prosthetic Arm is to engineer and design an arm that will help position the hand in three-dimensional space. The arm should allow the hand to reach the mouth as well as the dinner table (tray) to allow the user to […]

Written by: Carolina Barrera Our muscles are controlled, and usually move thanks to electric impulses that produce contraction in these, and the reaction to that contraction is what we know as a movement. Electromyography technology was developed to evaluate and record this electrical activity. Myoelectric signals are becoming popular in medicine and prosthetic technology probably […]
