Look inside

Let your robot drive itself! Your company, RoboPrototypes, is preparing to demo its autonomous beverage delivery robot to investors soon, but the technician who was supposed to drive it has quit. Since there’s no one to take his place, your CEO has tasked you with upgrading the robot with automatic navigation. You’ll set up Nav2 to load your desired parameters, implement navigation planners and controllers, and optimize navigation by tuning costmap parameters. Once you send your waypoint goals to Nav2 telling your robot where to go, it’ll be ready to quench thirsts at a food court near you.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.
