DEXTER: A SMART PROSTHETIC FOR TRANSRADIAL AMPUTEES
description
A below-the-elbow prosthesis that can adjust its position, orientation, and grip based on visual and force feedback to detect objects and perform everyday activities. Dexter is the first intelligent anthropomorphic hand for everyday use and advanced research alike and provides an inexpensive, intuitive, and intelligent alternative to existing prosthetic hands.
Features
-
Independent movement of three fingers, one thumb, wrist roll, and wrist pitch. Controlled with custom PID
-
Seven force-sensitive resistors to provide “feeling” to hand
-
IMU orientation feedback relative to global coordinate system provides self-balancing
-
Rotary potentiometers to provide real-time angular feedback
-
Embedded board for control of drivers, sensors, and camera
-
3D point cloud camera with custom algorithms for object detection and tracking
-
Device was 3D printed in ABS to reduce weight, cost, and production time
