Research Statement

Seeking higher levels of autonomy, unmanned systems require efficient, robust and implementable  NGC (Navigation, Guidance and Control) methodologies. Our group is currently working on developing novel guidance and path planning solutions for autonomous vehicles. The research areas include vision based guidance, path planning in urban terrain, evasion tactics and optimization, UAV formation guidance and collision avoidance.
