Bringing Large Models to Raw Silicon

For an embodied robotic system to converse and make decisions without external network dependency, large neural architectures must fit within stringent memory, thermal, and compute constraints.

Bringing Llama-3 to the Edge: End-to-End Quantized Conversational AI on Raspberry Pi 5

Engineered an on-device voice-to-voice conversational intelligence pipeline integrating Whisper automatic speech recognition (ASR), a quantized 3B Llama-3 model, and neural text-to-speech (TTS), executing fully on-device on a Raspberry Pi 5 without external API dependencies. This architecture serves as the computational backbone for untethered robotic agents operating in compute-constrained environments.

Autonomous Vision-Guided Pick-and-Place Robotic Arm

Engineered an autonomous pick-and-place system for a multi-DOF articulated robotic arm in ROS 2 (Humble) and Gazebo. Formulated closed-form analytical Forward and Inverse Kinematics (FK/IK) delivering deterministic sub-millimeter trajectory execution (<80 μs compute time), integrated with an eye-in-hand OpenCV computer vision pipeline (dual-band HSV chrominance segmentation and spatial moment centroid extraction) for closed-loop visual servoing and dynamic object acquisition.
