Long rehabilitation time and possible debilitating tendon adhesion is a growing concern in patients who have undergone hand surgery in the fast-paced modern world. To combat these issues, the deXassist device is proposed
Testing was completed in early November to validate the use of SMA actuators for the deXassist system
With prototype 2 deXassist is able to take advantage of a shorter length of SMA wire while still providing a full range of movement.
High accuracy posistion control has been achieved on prototype 2. Using bang-bang control, see the deXassist prototype step between 30 and 70 degrees.
The deXassist system is being built. Using aluminum and delrin our designs are becoming a reality. Soon the electrical and controls system will be integrated and the project will be complete.
The palm has been printed and is ready for the finger to be attached.
Prototype 4 is assembled and actuating the MCP joint
