Current Work

Dynamic modeling and control of a Micro Robotic Deposition System, with bone scaffold manufacturing as the target application. In this research, precision motion control techniques will be explored to achieve the high levels of precision and response time demanded by microscale applications. Sensing techniques and control algorithms will be employed to enable printing of bone scaffolds with advanced architecture.
