I am a first-year Master of Applied Science student at UTIAS (University of Toronto). Currently, I work under the supervision of Professor Angela Schoellig, Dynamic Systems Lab, UofT Robotics Institute on safe multi-robot motion planning.

I completed my Bachelors in ECE at Sardar Vallabhbhai National Institute of Technology. I have worked as an undergraduate researcher under Prof. Arun Kumar Singh, IMS Robotics, University of Tartu on trajectory optimization and model predictive control. In the past, I did summer reseach internship under Prof. K Madhava Krishna, Robotics Research Center, IIIT Hyderabad. In my sophomore and junior year, I was an active member of my institute's technical club Drishti, participating in Asia-Pacific Robot Contest, building a 50lbs autonomous wheeled mobile robot from scratch.

Projects

  1. Safe Multi-Robot motion planning

  2. On-going

  3. Multi-Modal MPC for autonomous driving

  4. Research Project: Developed a real-time MPC algorithm that captures different driving modalities by generating several goal-directed trajectories in parallel; the resulting trajectories are ranked based on a meta-cost function to accomplish a high-level driving objective.

  5. Fixed-Wing-Aerial Vehicle Trajectory Optimization in Urban Settings

  6. Research Project: Developed a novel optimizer which exploits the computational structure of the non-linear trajectory optimization problem. Our optimizers builds an insight that the seemingly non-linear trajectory optimization has an implicit multi-convex structure. It outperforms the state-of-the-art implementation of SQP ACADO Toolkit in terms of computation time and solution quality.

  7. Occlusion-Free Target Tracking with Quadrotors

  8. Research Project: Developed a fast MPC algorithm that can run real-time laptops and devices such as Jetson TX2 for the problem of quadrotor tracking a target. Our approach relies on novel reformulations for the tracking, collision, and occlusion constraints that induce a multi-convex structure in the resulting trajectory optimization. We exploit these mathematical structures using the split Bregman Iteration technique, eventually reducing our MPC to a series of convex Quadratic Programs solvable in a few milliseconds.

  9. Multi-Robot System for Warehouse application

  10. Final Year Project: Developed a multi-robot navigation system by incorporating diverse concepts and algorithms such as distributed model predictive control, A* search algorithm, On-demand Collision Avoidane, and Leader-Follower formation scheme. The problem statement was divided into three parts: single-robot navigation, multi-robot navigation, multi-robot cooperation to transport a deformable object. We validated and tested algorithms in Gazebo environment.
