    Bionic Robotic Hand controlled by myo-electric signals

    Several designs and products are currently available online as complicated limbs and hands for amputees, however many of these can be costly and heavy. This project has taken inspiration from these designs with the goal of reducing cost and weight without sacrificing functionality. One major advantage of our project is flex- ibility, easy to use and to wear. In this project we have developed a prosthetic hand controlled by myoelectric signals captured from the forearm muscle. This signals were filtered and amplified to be easier to read by a micro-controller. The micro-controller then generated signals to control the mechanical hand based on these myoelectric input signals. This is done by the micro-controller increasing the pulse width sent to several servos making up the hand. The larger the pulse width, the more flexed the hand becomes until it reaches the maximum pulse programmed into it. In addition to that, we have developed a dynamic website for the sale of the prosthesis, where the client can find all the information related to this product.
