Practice the ROS2 Modular End-Effector System coding problem in Software Architecture. Browser-based execution with automated grading — no local ROS install required. 42% of engineers pass this challenge.

Problem Statement

Design a modular ROS2 system that allows swapping robot end-effectors (gripper, suction cup, welding torch) with minimal code changes, demonstrating proper software architecture principles.

Requirements

Your modular system must:

  • Score ≥85% on automated code quality checks
  • Support hot-swapping without node restart
  • Implement plugin architecture or factory pattern
  • Provide clear interface documentation
  • Allow changing effectors in <10 lines of code
  • All effectors must implement a common IEffector interface

Input/Output Format

Input: /target_pose | Output: /joint_commands

⚠️ Common Pitfalls

  • Singularities in workspace
  • Joint reach limits
