Airport luggage handling robot on ROS 2 Jazzy. Raspberry Pi 5 (16GB) + Hailo-10H AI HAT+ for 40-TOPS edge inference. Drive chain: RPi to ESP32 motor controller to dual BTS7960 H-bridges to 40Kgcm DC motors. ESP32 sensor fusion node runs a Kalman filter. B2B target: airport operators at Rs.7L/unit + Rs.1.1L ARR.

Electrothermal simulation of mushroom-type and confined/pillar-type Phase Change Memory cells. 2D axisymmetric model using Heat Transfer in Solids + Electric Currents physics. GST conductivity modeled with Poole-Frenkel + Arrhenius (beta=3.509e-24, Ea=0.09eV). HfO2 layer and time-dependent pulse study in progress.

Writing a full ROS 2 Jazzy driver from scratch to deeply understand the middleware — publisher lifecycle, QoS profiles, custom message types, and sensor integration patterns.

SystemVerilog OOP practise — base/derived classes, shallow copy, testbenches. Studying UVM, assertions, and functional coverage for Digital Design Verification Techniques (final semester).
