LLM-Controlled Robotic Dog
Robotics • December 19, 2025
Autonomous robotic dog controlled through natural language using Claude API and ESP32 microcontroller. Performs complex choreographed sequences including backflips, push-ups, and stretches through conversational commands.
Key Features
- •Natural language command interpretation using Claude API
- •ESP32 microcontroller serial communication
- •Autonomous multi-step action sequences
- •Gyroscope-based auto-correction for balance
- •Complex choreography engine (backflips, push-ups, stretches)
- •Real-time movement coordination
- •Hardware-software integration with LLM control
- •Conversational robotics interface
This project demonstrates the intersection of large language models and robotics by enabling natural language control of a physical robotic dog. Instead of pre-programmed commands, the robot interprets conversational instructions and executes complex movement sequences.
Architecture
The system bridges AI and hardware through three core components:
- Claude API Integration: Processes natural language commands and translates them into action sequences
- ESP32 Microcontroller: Handles real-time motor control and sensor feedback
- Serial Communication Protocol: Ensures reliable command transmission between Python host and embedded system
Capabilities
Natural Language Control: Give commands like "do three backflips then take a bow" and watch the robot interpret and execute the sequence autonomously.
Gyroscopic Stabilization: Built-in IMU provides auto-correction, enabling the robot to maintain balance during complex maneuvers.
Choreographed Sequences: The robot performs intricate multi-step routines including:
- Dynamic backflips with landing stabilization
- Push-up sequences with proper form
- Stretching movements for demonstration
- Custom action chains from conversational input
Technical Implementation
The Claude API acts as the "brain," understanding context and intent from natural language. It generates movement primitives that the ESP32 executes through precise servo control. Gyroscope feedback creates a closed-loop system where the robot adjusts movements in real-time.
