Mastering robots in the company of professors doesn’t require a classroom. Or even pants. EdX, a remote-learning site run by Harvard and MIT, offers dozens of free online courses, including one called Autonomous Mobile Robots. We audited a class to see what it entailed. Here’s how you, too, might pick up the skills to program bots that can navigate and map a room.

Lectures: Instructors from the Swiss Federal Institute of Technology in Zurich walked us through key concepts in a series of web videos, including robotic locomotion and obstacle detection.

Homework: After each lecture, the instructors assigned a problem set covering the material and encouraged any overachievers to try additional exercises.

Simulator: The additional exercises involved a downloadable simulator, which allowed us to control a virtual robot named Bob. We coded in MatLab and Octave to help Bob avoid obstacles in its virtual environment.

Office hours: If students got stuck, they could log in to an interactive forum that connects them directly to professors and study buddies around the world.
