It wasn’t a musical instrument, snoring, nor someone talking in a monotone.

Students in STEM 9 were working on a number of different projects — audio, photo and video editing, remote controlled flight simulators, and drones.

With equipment from For the Win Robotics and the Robotics Education and Competition Foundation (REC), the program offers drones, different control systems, and physical targets and obstacles.

At first, students in Art Anderson’s class use a handheld controller. Eventually, “we have an app and they program it to fly autonomously,” he said.
