Hardware Assembly & Motor Rewiring
Manual wired remote bypassed — 5 DC motors soldered directly to H-bridge drivers on Raspberry Pi GPIO.
OpenAI Whisper Speech-to-Text
Real-time microphone audio capture and speech-to-text transcription via OpenAI Whisper.
GPT Prompt-to-Action Mapping (2022)
Natural language intent mapped to discrete motor primitives (motor1-up, gripper-open, led-on).
Python GPIO Motor Controller
Timed GPIO pulse execution driving H-bridge channels for smooth joint and gripper motion.
