1. Control robotic hand exoskeleton with motor neurons • Proposed the cortically controlled robotic hand skeleton system. • Leader of a team of three to design, manufacture and control the first prototype monkey-sized robotic hand exoskeleton. • Solved the challenges of designing mechanoeletrical system in ultra-small scale and limited space. • Developed software for each of the subsystem, main application (Matlab), real-time controller (Simulink Realtime/XPC), robotic system user GUI (Matlab), neural decoder (Multithreaded C/Linux), and rewarding system (Embedded C). • Applied state-of-art machine learning algorithms in decoder design and neural data analysis. 2. Kinematic control of biomimic actuated thumb exoskeleton • Derived and analyzed kinematics of 11 joints thumb skeleton with non-orthogonal and off-set axes. • Improved rotation measurement accuracy and linearity by using non-contacting hall-effect sensor. • Modelled and simulated the 11 joints coupled exoskeleton kinematic control in Simmechanics. 3. Hand robotic skeleton for stroke patient joint stiffness evaluation • Dramatically reduced system run-time failures by converting the entire system software from QNX C based to LabVIEW Realtime based. • Solved the stability problem in high speed tracking by building customized PID controller with additional tachometer input. • Provided therapists with safe, reliable, and easy user interface to operate robotic exoskeleton for clinical stiffness evaluation and manage data. • System smoothly run 120+ evaluations for 40+ stroke patients in hospital environment.

BME330 Analysis of Biosignals and Systems (Fall2012, Fall2013)

• Flash memory selection, integration and testing for GPS datalogger. • Programmed serial communication software between PC host and datalogger.
