ROS2 ROS2 Parameter: Dynamic Speed Update

Easy Parameters 0% pass rate

Practice the ROS2 ROS2 Parameter: Dynamic Speed Update coding problem in Parameters. Browser-based execution with automated grading — no local ROS install required. 0% of engineers pass this challenge.

Problem Statement

Use parameters to control a simulated robot's speed variable dynamically.

Requirements

  • Node speed_controller
  • Parameter target_speed (float, default 0.0)
  • Timer callback prints "Current Speed: [value]"
  • Allow external tools (simulated test script) to change target_speed.

Input/Output Format

Output:

  • Console logs reflecting the parameter value updates.

⚠️ Common Pitfalls

  • Caching the parameter value once in __init__ and never reading it again.
