Open to work

Multi-robot systems that sense, decide and coordinate.

I'm Sai Aravind CH, a robotics software engineer with four years of experience building multi-robot systems: decentralized fleet coordination, drone swarms and simulation. I'm now doing an M.Eng. in Robotics at the University of Maryland, College Park, to go deeper into perception-driven behavior control: robots that decide what to do from what they sense, and teams of them that do it together.

  1. Oct 2025 – Aug 2026

    Software Engineer, Distributed Systems · LexxPluss

    Tokyo, Japan

    • Designed an auction-based task allocation algorithm where robots bid for tasks, removing the central-manager bottleneck and single point of failure.
    • Built a Zenoh pub-sub layer streaming real-time telemetry across the fleet, enabling low-latency decentralized decision-making.
  2. Aug 2023 – Oct 2025

    Robotics Software Engineer · NewSpace Research and Technologies

    Bangalore, India

    • Implemented Reciprocal Velocity Obstacles (RVO) collision avoidance and state-machine behavior for a heterogeneous fleet of fixed-wing aircraft and multicopters.
    • Cut inter-drone bandwidth by 60% with LCM communication over a WiFi mesh.
    • Built simulation tooling (Gazebo terrain generator, payload-drop and target-tracking modules) to test missions virtually before flight.
    • Ran field tests and verified simulation behavior against real-world deployment at scale.
    • Integrated an in-house flight dynamics model with JSBSim for Collaborative Combat Aircraft work, shown at AERO India 2025.
  3. Jun 2022 – Jul 2023

    Robotics Software Engineer · Unbox Robotics

    Pune, India

    • Designed a state-machine task allocation algorithm and a predictive battery scheduler for a sorting-robot fleet, improving uptime.
    • Built ROS2 fleet-manager-to-robot communication with static peer discovery, removing dynamic broadcast traffic at scale.
    • Built a shared error-handling pipeline across robot types, cutting per-robot development effort.
    • Led a configuration manager and OTA firmware module; deployment time down 50%, update time down 86%.
