Week 04 - Command Line And Python Simulation

Task Goal

This week practices command-line operation, robot basics, and Python simulation thinking. The task is to move from manual command execution toward repeatable scripted robot behavior.

|-- images/            # recommended media

Environment

• Python
• ROS2 concepts
• Terminal

Steps

1. Review command-line workflow.
2. Study simple robot motion concepts.
3. Prepare Python simulation logic.
4. Record the workflow in README form.

Commands

python3 motion_script.py
ros2 topic list

Result

This week documents the transition from manual terminal control to scripted motion logic.

Summary

Python scripting helps make robot experiments repeatable. Even when the task is basic, recording commands and intended output makes the week easier to evaluate.
