Aug. 22, 2022 -- NSF Awarded Project on Autonomous Fault-Tolerant Redundant Robotic Arms

Aug. 22, 2022 -- A new project entitled "Autonomous Fault-Tolerant Operation of Redundant Robotic Arms", was awarded recently by NSF. Dr. Biyun Xie and Dr. JiangBiao He, both from UK ECE, will serve as the PI and Co-PI, respectively, to lead this 3-year project.

Hazardous environments with extreme temperature, humidity, radiation, etc. escalate the potential risk of hardware failures of robot joint motors and drives. Unfortunately, in unstructured, remote and dangerous environments, such as space exploration, nuclear waste remediation, and disaster rescue, not only are failures more likely to occur, but also it is impossible to perform routine maintenance for these robots after a failure occurs. Besides the above situations, failures occurred in safety-critical robotic applications, could also lead to serious consequences or accidents. Therefore, this project will develop autonomous fault-tolerant and fail-active strategies for redundant robot arms based on predicted and identified joint faults, which will dramatically improve the reliability and robustness of redundant robot arms.

April 12, 2022 -- 3-Year Project Awarded by ONR on WBG Machine-Drive Systems for Electric Propulsion

April 12, 2022 -- A 3-year project has been awarded recently by ONR to develop an advanced integrated solution for machine-drive electric propulsion systems, aiming to improve the system reliability in safety-critical applications. Dr. He serves as the PI to lead this project. 

The emerging wide bandgap (WBG) semiconductor switches have been increasingly utilized in electric propulsion drives over the past few years, in order to enhance energy efficiency and power density of propulsion drivetrains. However, the fast switching speed of the WBG switches also induces notable reflected voltage stress on the stator windings and high-frequency current in the bearing of the machines, resulting in premature aging or failures in propulsion machines (see Dr. He's tutorial in IEEE IEMDC-2019 for more details). This has become a pressing concern for safety-critical applications such as electric ships or electric aircraft, particularly for the medium-voltage high-power propulsion systems in these applications. In this project, Dr. He's team will develop an advanced integrated solution to address such challenges and improve the propulsion system reliability.
