Casey Smith caseysmith@vt.edu

After obtaining his BS in Mechanical Engineering from Rowan University (New Jersey), Casey Smith worked for Canon Virginia Inc., where he designed and programmed robotic assembly systems. Experience with 6-axis and self-driving robots led him to Virginia Tech to pursue research with autonomous systems.

Casey Smith's work is focused on analyzing and reducing the collateral damage created by precise counter-UAV systems for deployment in potentially cluttered airspaces. A working knowledge of UAV PNT architecture, GNSS, and RF devices is required. His work consists of derivations from first principles followed by MATLAB simulations.
