Research

My interests span multi-agent coordination, control, vision, LLMs, and chain-of-thought reasoning. I study how to turn perception into verifiable action and create agents that plan step by step, justify decisions, honor safety constraints, and scale to crowded, partially observed environments in both software and robotics. My goal is to create reliable, interpretable reasoning agents that spans LLM tools and embodied systems explaining their choices, and transfer from simulation to real settings across robots, interactive assistants, and complex software workflows.

Projects

A Benchmark and Survey of Deadlock Resolution in Multi-Robot Navigation in Social Mini-Games

Autonomous navigation and trajectory planning of a robot using Robot Operating System (ROS). A maze is created in gazebo for the robot to determine the best possible trajectory with collison avoidance. Probablistic localization method is used for navigation. Adaptive Monte Carlo Localization(AMCL) node and slam_gmapping package is used for localization of robot and mapping of robot. Rviz interface is used for the simulation of robot and creating the cost map for the travel of robot.

Obstacle avoidance implemented in Robot operating system for Unmanned Aerial Vehicle (UAV) using LiDAR scan data. Hector quadrotor package is used for spawning the drone in the gazebo environment. Readings from SONAR sensor with python script is used for flying the drone to a certain height. LiDAR readings are used to detect obstacles in the surroundings.

Path planning of point robot for finding shortest path between start and goal position. Implemented Informed and Uninformed search algorithms for the path planning problem. A random 2D enivronment is created with obstacles for evealuation of searching algorithms. A* and Dijkstras algorithm is implemented for obtaining the shortest path. Investigated the perofrmance by implementing other search based algorithms such as Best first, Depth First and Breadth First for finding the shortest distance. Given below are the images of search done by the various algorithms.
