Topo-Geometrically Distinct Path Computation using Neighborhood-augmented Graph, and its Application to Path Planning for a Tethered Robot in 3D
Alp Sahin, Subhrajit Bhattacharya
Many robotics applications benefit from being able to compute multiple locally optimal paths in a given configuration space. Examples include path planning for of tethered robots w…
Forming and Controlling Hitches in Midair Using Aerial Robots
Diego S. D'Antonio, Subhrajit Bhattacharya, David Saldaña
The use of cables for aerial manipulation has shown to be a lightweight and versatile way to interact with objects. However, fastening objects using cables is still a challenge and…
Multi-Agent Exploration of an Unknown Sparse Landmark Complex via Deep Reinforcement Learning
Xiatao Sun, Yuwei Wu, Subhrajit Bhattacharya +1
In recent years Landmark Complexes have been successfully employed for localization-free and metric-free autonomous exploration using a group of sensing-limited and communication-l…
Coordination-free Multi-robot Path Planning for Congestion Reduction Using Topological Reasoning
Xiaolong Wang, Alp Sahin, Subhrajit Bhattacharya
We consider the problem of multi-robot path planning in a complex, cluttered environment with the aim of reducing overall congestion in the environment, while avoiding any inter-ro…
Training Robust Graph Neural Networks with Topology Adaptive Edge Dropping
Zhan Gao, Subhrajit Bhattacharya, Leiming Zhang +3
Graph neural networks (GNNs) are processing architectures that exploit graph structural information to model representations from network data. Despite their success, GNNs suffer f…
Pursuer Assignment and Control Strategies in Multi-agent Pursuit-Evasion Under Uncertainties
Leiming Zhang, Amanda Prorok, Subhrajit Bhattacharya
We consider a pursuit-evasion problem with a heterogeneous team of multiple pursuers and multiple evaders. Although both the pursuers (robots) and the evaders are aware of each oth…
