Biography Summary

Glenn Heppler is a Professor in the Department of Systems Design Engineering and cross-appointed to the Mechanical and Mechatronics Engineering department at the University of Waterloo.

Professor Heppler’s research interests include the dynamics of structures, and multilink and single link systems. He is pursuing several research projects that involve the dynamics and control of a wide range of flexible structures. These structures range from flexible robotic manipulators, to bridges, and to structures with significant gyroscopic elements.

The study of structurally flexible robotic arms is also being pursued by Professor Heppler in the context of dynamic mass capture. Dynamic mass capture is the acquisition of a payload by the robot when there is a significant nonzero relative velocity between the robot end effector and the payload. Both the modelling of the dynamics of this class of systems and the control of the system behaviour is being examined in his research.

Additionally, Professor Heppler has several publications on subjects such as natural frequencies and large-stroke electrostatic micro-actuators.
