Online, scalable, distributed, and safe trajectory generation algorithm for quadrotor swarms in cluttered and complex environments.
Multi-Modal MPC for autonomous driving
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.
Fixed-Wing-Aerial Vehicle Trajectory Optimization in Urban Settings
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.
Occlusion-Free Target Tracking with Quadrotors
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.
Multi-Robot System for Warehouse application
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.
Asia-Pacific Robot Contest
Competition: Developed an autonomous navigation system for Omni-directional robots from its embedded system to motion planning and control.
Personal Project: Followed RI16-730 Planning techniques in Robotics and implemented planners such as A*, ARA*, D*, Wave front planner, navigation potential functions, etc. Moreover, wrote blogs🔗 on implementation and results.
