A Bayesian Modeling Framework for Estimation and Ground Segmentation of Cluttered Staircases

Prasanna Sriganesh;Burhanuddin Shirose;Matthew Travers

IEEE Robotics and Automation Letters

Year: 2025 | Volume: 10, Issue: 5 | Journal Article |

HTML

Autonomous robot navigation in complex environments requires robust perception as well as high-level scene understanding due to perceptual challenges, such as occlusions, and uncertainty introduced by robot movement. For example, a robot climbing a cluttered staircase can misinterpret clutter as a step, misrepresenting the state and compromising safety. This requires robust state estimation method...Show More

GESCE: Graph-based Ergodic Search in Cluttered Environments

Burhanuddin Shirose;Adam Johnson;Bhaskar Vundurthy;Howie Choset;Matthew Travers

2024 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)

Year: 2024 | Conference Paper |

HTML

In this paper, we present a novel motion planning algorithm that inherits the strengths of both optimization and search-based planners. Optimization-based planners use the gradient of an objective function to generate a desired path, whereas search-based planners operate on a graph capturing the salient topology of a robot’s free space. A class of optimization-based planners leverages prior inform...Show More

Longitudinal Control Volumes: A Novel Centralized Estimation and Control Framework for Distributed Multi-Agent Sorting Systems

James Maier;Prasanna Sriganesh;Matthew Travers

2024 IEEE International Conference on Robotics and Automation (ICRA)

Year: 2024 | Conference Paper |

HTML

Centralized control of a multi-agent system improves upon distributed control especially when multiple agents share a common task e.g., sorting different materials in a recycling facility. Traditionally, each agent in a sorting facility is tuned individually which leads to suboptimal performance if one agent is less efficient than the others. Centralized control overcomes this bottleneck by levera...Show More

Cited by: Papers (19)

HTML

Modular robots can be rearranged into a new design, perhaps each day, to handle a wide variety of tasks by forming a customized robot for each new task. However, reconfiguring just the mechanism is not sufficient: each design also requires its own unique control policy. One could craft a policy from scratch for each new design, but such an approach is not scalable, especially given the large numbe...Show More
