How to Teach Robot Path Recording and Replay

In this video, you'll see how to teach Robot Path Recording and Replay.

Asking a robot to “go back the way it came” sounds hard, but it isn’t once you see the trick: the places a robot passes through are just data you can save in a list. Record where it goes on the way out, then read that list backwards, and returning home is simply visiting each spot again in reverse — no map, no planner, no new navigation.

Learning Points:
✅ Build a single node that quietly remembers where the robot has been as you drive it along any path you like.
✅ Store only the spots that matter — a fresh one each time the robot has moved a set distance — so the path stays a compact, tidy trail rather than thousands of near-identical points.
✅ Trigger a replay so the robot retraces its steps back to where it started, driving to each remembered spot in reverse.
✅ Reuse the exact same code to run three robots at once, each independently recording and replaying its own path.

============================

[For Robotics Teachers Open Class], a weekly series of videos by The Construct Robotics Institute, aims to make robotics education easier by helping teachers teach a wide range of robotics topics through hands-on practice.

Each session provides a ROS-based project (referred to as ROSJECTs 🦾 📁) for all attendees, including notebooks, code, and robot simulations. Led by ROS expert Desire, you'll see how robotics teaching and hands-on practice come together in real time.


We're excited to share this series with you! If you have questions or want to explore new topics, drop us a comment below.
