Hi, I'm Shourya 👋

Field robotics @ UAS-DTU · DARPA Triage Challenge, 2nd place (non-funded) · Mathematics & Computing @ DTU

I build autonomy for robots that have to work outside the simulator. On UAS-DTU's DARPA Triage Challenge team I work across the full stack of our autonomous ground rover and drones: perception, localization, navigation, control, and the hardware underneath.

What I work on

  • Real-world rover autonomy: Blickfeld 3D LiDAR, LiDAR-inertial odometry, Nav2 and MAVROS on an ArduRover (Cube Orange+) platform with an onboard Jetson, taken from Gazebo to outdoor field runs.
  • Localization benchmarking: GenZ-ICP, SuperOdometry, VINS-Fusion and ArduPilot EKF3 compared against RTK-GPS ground truth on the same outdoor runs; 2D maps with SLAM Toolbox for Nav2.
  • Control: an adaptive velocity controller in ROS 2 that learns the rover's response online, with separate left- and right-turn gains, to close the gap between what Nav2 commands and what the rover actually does.
  • Drone autonomy: autonomous lawnmower area-coverage missions on ArduPilot, DroneKit missions with a hand-written PID position controller in SITL, and build and flight prep of Tarot, ShadowX and other UAS-DTU airframes.
  • Simulation and digital twins: a SUMO digital twin of Delhi's ITO corridor, built from real traffic data, with adaptive signal control and a live Gazebo 3D view (Team Pravah, Smart India Hackathon 2026).

Field debugging

Most of what I've learned came from failures that don't announce themselves:

  • undetected frame misalignments that left us with wrong sensor extrinsics
  • LiDAR–IMU time offsets and motion distortion
  • LiDAR odometry degrading in feature-poor areas
  • odometry published without covariance, which our EKF couldn't fuse
  • compass-driven heading drift in the flight controller
  • USB 3.0 interference knocking out CAN GPS

When the robot misbehaves, I check frames, timestamps, covariances and the physical setup before I touch a single tuning parameter.
