This paper studies high-speed online planning in dynamic environments. The problem requires finding time-optimal trajectories that conform to system dynamics, meeting computational constraints for real-time adaptation, and accounting for uncertainty from environmental changes. To address these chall
Modeling the energy consumption of a quadrotor involves complex electrical and physical dynamics, making it difficult to optimize. To address this challenge, this paper presents a multi-fidelity Gaussian process (MFGP) method that efficiently learns an accurate energy prediction model by combining m…
Efficiently navigating off-road environments presents a number of challenges arising from their unstructured nature. In the absence of high-fidelity maps, occlusions from obstacles and terrain lead to limited information available to inform planning decisions. Furthermore, resolution and latency lim…
We present a modular Bayesian optimization framework that efficiently generates time-optimal trajectories for a cooperative multi-agent system, such as a team of UAVs. Existing methods for multi-agent trajectory generation often rely on overly conservative constraints to reduce the complexity of thi…
Generating time-optimal quadrotor trajectories is challenging due to the complex dynamics of high-speed, agile flight. In this paper, we propose a data-driven method for real-time time-optimal trajectory generation that is suitable for complicated system models. We utilize a temporal deep neural net…
We consider the problem of generating a time-optimal quadrotor trajectory that attains a set of prescribed waypoints. This problem is challenging since the optimal trajectory is located on the boundary of the set of dynamically feasible trajectories. This boundary is hard to model as it involves lim…
