About Me.
I'm a robotics researcher passionate about autonomous mobile robots. I envision a future where my drone picks up my groceries at the push of a button. The idea of autonomy in vehicles and robots excites me, and I want to contribute to this field. My areas of specialization are Trajectory Planning and SLAM.
​
Outside of research, I'm a gym rat and a trained bachata dancer.

PROJECTS
Zero-clamped C2-continuous Quintic Time Trajectories
•Implemented a path smoothing algorithm using quintic time trajectories to achieve C2 continuous global trajectories for a self-navigating ground robot.
•Identified and resolved path divergence issues caused by angular velocity discontinuities in initial cubic trajectory models.
•Developed quintic blending for seamless transitions between linear path segments generated by a modified A* algorithm.
•Identified conditions to confine the trajectory within the convex hull of consecutive linear segments
•Derived an analytical solution for determining permissible blend times based solely on boundary conditions, eliminating computationally expensive iterative checks.
Vectorial approach to Particle Filter weighting
•Developed a novel vector-based weighting method for particle filters, improving robustness to outliers and symmetric map ambiguities in global localization.
•Achieved more successful global localization by replacing the standard sensor model implementation with proposed method in localization pipelines.
•Authored a first-author manuscript on this innovative approach, currently under review at ICASSP 2025.
Cross-Sensor Point Cloud Registration
​
•Implemented cross-sensor point cloud matching using ArUco markers, integrating camera and depth sensor data
•Developed a robust method for detecting and estimating the pose of ArUco markers, enhancing the precision of 3D mapping.
•Achieved seamless point cloud alignment, improving the efficiency and accuracy of multi-sensor fusion in complex environments.
Multi-agent path planning using HCA*
•Implemented Hierarchical Cooperative A* (HCA*) for a warehouse management-oriented startup.
•Generated collision-free multi-agent trajectories, optimizing the efficiency and safety of warehouse operations.
Orientation aware modified A* algorithm
•Developed an orientation-aware A* algorithm respecting non-holonomic constraints of ground robots.
•Optimized the search space by biasing easier motions, narrowing down to more likely waypoints and reducing the number of steps to reach the goal.
•Implemented a method to prevent sharp turns, aiding higher curvature blends.
•Achieved faster cornering as a result of the implemented method.
Localization and Autonomous Navigation
•Achieved real-time global localization using particle filter with mean error of 10 cm and 0.4 rad in a 13x15 meter room on all successful attempts using MATLAB.
•Implemented the A* algorithm for path planning
•Applied piecewise-stitched cubic time trajectories using obtained waypoints, ensuring global velocity continuity and piecewise acceleration continuity.
Rhythmic flight with Quadcopter
•Achieved music-synchronised quadcopter movement in a confined three-dimensional space using MATLAB.
•Utilized Fast Fourier Transform to identify prominent frequencies and track their intensity changes over the piece of music.
•Identified patterns in varying intensities over multiple octaves to determine the time to traverse segments.
•Applied 1-dimensional cubic time trajectories to ensure smooth velocity profiles.
