Dr. Ro is interested in precision machining, robotics, manufacturing automation, control theory, and system dynamics.

Dr. Ro teaches Linear Control and Design of MIMO (multi-input multi-output) Systems (MAE 521) and Real-Time Robotics (MAE 544). The MIMO System course is a fundamental graduate-level course that introduces students to the time-domain approach. His Robotics course provides a strong analytical foundation in kinematics, rigid-body dynamics, and motion control of robot manipulators. At the undergraduate level, Dr. Ro teaches Dynamics of Machines (MAE 315) and Principles of Automatic Control (MAE 435). In Dynamics of Machines, Dr. Ro enriches the course with discussions about how motors can exploit vibration to move things. His Controls class is a classical treatment that places a strong emphasis on frequency-domain methods.

Dr. Ro’s students are independent, motivated, and hard-working. They tend to be drawn to Dr. Ro’s research because of the good mix of analytical and experimental work and because of the interesting subject matter.

Outside of work, Dr. Ro spends time with his family and leads an active church life.

Research Description

Dr. Ro's research leads to new ways of harvesting ambient energy. He is currently 1) developing cooling systems for low-power hand-held devices, 2) developing a vibration energy harvesting device for power suspension systems, and 3) studying design and control methodologies for mobile systems that possess deformability and autonomy. Within MAE he collaborates with Dr. Dow, Dr. Kuznetsov, and Dr. Zhu.
