Avatar: In this project, we are working with the Human
Centered Robotics Lab led by Prof.
Luis Sentis and the Neural
Networks Research Group led by Prof.
Risto Miikkulainen in the University
of Texas at Austin to build a semi-autonomous robotic
system named Cyberphysical Avatar. Cyberphysical Avatar is
designed to be able to adjust to unstructured environments
and perform physical tasks subject to critical timing
constraints while under human supervision. It integrates
recent advance in three technologies:
Mobile Gait Rehabilitation System: In this project, we
are working with the Mechanical
Systems Control Lab led by Prof.
Masayoshi Tomizuka in University
of California, Berkeley to build a networked mobile
assistive system to transform outpatient rehabilitation from
a closed environment at a hospital or rehabilitation center
to an open, home or community environment.
We deployed a wireless body sensor network on the patient side by integrating heterogeneous medical sensors and actuators (including air pressure sensors and inertial sensors) on our low-power and real-time wireless communication platform. Real-time sensor data collected from patients will help remote physical therapist to make high-level decision and provide dynamic and appropriate training plans for the patients.
Our preliminary result is available here. We are performing clinical testing in UCSF medical school to validate our system design and evaluate the performance of the designed control algorithms in real hospital environment.
WirelessHART: Low-Power Reliable and Real-Time Wireless Sensing and Control Network: In this project, we work with the Future Architecture Department led by Mark Nixon in Emerson Process Management to design and develop the WirelessHART real-time communication platform, which is the first open wireless communication standard for industrial wireless real-time sensing and control applications. Our achievements include:
Data Management in Distributed and Dynamic Real-Time Sensing and Control Systems: In this project, collaborating with Prof. Krithi Ramamritham, Prof. Sang H. Son and Prof. Kam-yiu Lam, we studied the problem how to maintain sensor data freshness while maximizing control quality in real-time sensing and control systems especially in presence of dynamic workload in distributed systems. Based on different task models, we designed novel and efficient scheduling algorithms, presented thorough theoretical analysis on their schedulability, and did extensive experiments to validate their correctness and effectiveness. Our results are:
