ROS2 Cobot - IO Integration (Digital I/O)

Easy Cobot Programming 0% pass rate

Practice the ROS2 Cobot - IO Integration (Digital I/O) coding problem in Cobot Programming. Browser-based execution with automated grading — no local ROS install required. 0% of engineers pass this challenge.

Problem Statement

Simulate interacting with a Cobot's Digital I/O (Input/Output) board. Read a sensor state and trigger an effector.

Requirements

  • Node io_controller
  • Subscribe to /digital_inputs (im_msgs/DigitalInputs or similar std_msgs)
  • Publish to /digital_outputs (std_msgs/Bool)
  • Logic: If input[0] is TRUE, set output[0] to TRUE (turn on light).

Input/Output Format

Input:

  • /digital_inputs array

Output:

  • /digital_outputs (Bool)

⚠️ Common Pitfalls

  • Logic inversion (Active Low vs Active High).
