Multi-Agent Autonomy: Advancements and Challenges in Subterranean Exploration
Michael T. Ohradzansky, Eugene R. Rush, Danny G. Riley +9
Artificial intelligence has undergone immense growth and maturation in recent years, though autonomous systems have traditionally struggled when fielded in diverse and previously u…
3D Reactive Control and Frontier-Based Exploration for Unstructured Environments
Shakeeb Ahmad, Andrew B. Mills, Eugene R. Rush +2
The paper proposes a reliable and robust planning solution to the long range robotic navigation problem in extremely cluttered environments. A two-layer planning architecture is pr…
Real-time Quadrotor Navigation Through Planning in Depth Space in Unstructured Environments
Shakeeb Ahmad, Rafael Fierro
This paper addresses the problem of real-time vision-based autonomous obstacle avoidance in unstructured environments for quadrotor UAVs. We assume that our UAV is equipped with a…
APF-PF: Probabilistic Depth Perception for 3D Reactive Obstacle Avoidance
Shakeeb Ahmad, Zachary N. Sunberg, J. Sean Humbert
This paper proposes a framework for 3D obstacle avoidance in the presence of partial observability of environment obstacles. The method focuses on the utility of the Artificial Pot…
