Practice the ROS2 The Synchronized Swarm coding problem in Fleet / Multi-Robot. Browser-based execution with automated grading — no local ROS install required. 0% of engineers pass this challenge.

Fleet Problem

3 robots must arrive at target positions simultaneously for a coordinated task. Currently they navigate independently. Robot 1 (closest) arrives 30 seconds before Robot 3 (furthest). The task requires < 5 second spread.

Setup

  • 3 robots, each at a different starting distance from its target
  • Robot 1: 2m from target (fast arrival)
  • Robot 2: 4m from target (medium arrival)
  • Robot 3: 6m from target (slowest arrival)

Required behavior

  • All 3 robots must arrive within 5 seconds of each other
  • Total mission time should not be more than 50% slower than uncoordinated
  • Robots share estimated arrival times via /robot_N/eta topic

Your task

Implement coordination: robots share ETAs, and each robot adjusts its speed to arrive at the same time as the slowest.
