CURRENTLY BUILDING a Raspberry Pi-based, local voice assistant using wake-word detection, speech-to-text, a local LLM, and text-to-speech to act as the “brain” for a 0.75 m tracked robot. Set up a simple state-machine program that turns voice requests into clear robot commands (modes, safety stop, head/arm actions). Designed a servo-driven robotic arm for arm motions (shoulder, elbow, wrist, gripper), torque needs, etc. Designed and 3D printed mounts/enclosure parts and integrated the microphone, speaker, and power hardware for bench operation.
