Lab 5: VLA Chat Interface

Objective

Build a simple chat interface that controls a simulated robot.

Steps

1. Get OpenAI API Key: Sign up for OpenAI and get an API key.
2. Create ROS 2 Node: Write a Python node that:
   • Takes text input from the user.
   • Sends it to GPT-4 with a system prompt defining available actions.
   • Parses the response and executes the action (e.g., publish to /cmd_vel).
3. Test: Type "Move forward" and verify the robot moves.

Deliverable

The Python script for your chat node.
