About
Shreyas S Rai

Final-year Robotics & Automation Engineering student at Rajarajeswari College of Engineering, Bengaluru (VTU), graduating June 2026.

I build robots from scratch — mechanical design in Fusion 360, custom PCBs, embedded firmware, and complete ROS 2 navigation stacks. No kits. No shortcuts.

Currently leading hardware and firmware engineering for ArrayButton at IISc CPDM — a government-funded acoustic platform. Previously integrated ABB and FANUC robots into a hybrid manufacturing cell at IIT Dharwad.

Long-term target: Robotics Systems Architect — ROS 2 at scale, advanced SLAM, AI-driven perception.
