Design and control of 6DOF Upper Limb Prosthesis
Project Area of Specialization RoboticsProject SummaryOur project is the design and control of 6DOF upper limb prosthesis. A 3D printed prosthetic hand was made, with each finger being driven by a linear actuator.
This project is being implemented on an amputee, using electromyography signal sensors, along with the processing of and control using the signals acquired.
Project ObjectivesThe objective of the project is to implement a higher functional prosthesis on an amputee as compared to a mechanical gripper, which just offers full open and full close modes. As compared to other solutions in the market which cost around $4,000-10,000, this is a relatively cheaper solution.
Project Implementation MethodThe project has been implemented using
-3D printed hand
-Controlled using motor drivers and atmel microcontroller
-Signal acquired using resuable emg sensors with built in amplifier.
-Custom socket made for amputee to ensure good fitting
Benefits of the Project-Empowering amputees to perform daily tasks using the functionality of a human hand.
-Enabling amputees to perform various gestures and grip patterns
-Aiding amputees to recover from trauma by bringing back lost functionality due to loss of limb.
Technical Details of Final Deliverable-Developed algorithm for 4-5 grip patterns and gestures.
-Feedback signal for soft and hard grips (ie egg holding vs heavy weight holding)
-Algorithms for noise removal from acquired signal
-Atmega328P used to control and drive linear actuators as well as process emg signal using ADC.
