ROS2 Write Launch File for Multi-Robot Simulation

Medium Launch 0% pass rate

Practice the ROS2 Write Launch File for Multi-Robot Simulation coding problem in Launch. Browser-based execution with automated grading — no local ROS install required. 0% of engineers pass this challenge.

Problem Statement

Simulate a multi-robot fleet. Write a launch file that spawns two identical robots in different namespaces, preventing topic collision.

Requirements

  • Create multi_bot.launch.py
  • Launch two instances of my_bot_node
  • Namespace 1: /robot1
  • Namespace 2: /robot2
  • Remap /cmd_vel to /robotX/cmd_vel if needed (namespaces usually handle this automatically)

Input/Output Format

Output:

  • LaunchDescription starting 2 tagged nodes.

⚠️ Common Pitfalls

  • Forgetting that namespaces affect ALL topics, services, and parameters of that node.
