Summer scholar profile: Anu Gamage

Each year, the Summer Scholars Program awards funding to a select group of rising juniors and seniors from across Tufts academic disciplines, to carry out ten-week independent research projects. This summer, we profiled three engineering students as they worked on their projects.

Project: An inverted pendulum is exactly what it sounds like: a pendulum stood on its head, with its center of mass above its pivot. It requires a constant application of force to keep it balanced. The human body is an inverted pendulum, Gamage points out, with our muscles constricting to act against gravity and keep us upright. There are inverted pendulums in robotics and in aeronautics. They’re monitored by internal sensors that track the pendulum’s position and apply the proper amount of force to maintain its vertical position. Those internal sensors, however, are potentially vulnerable to software bugs or cyberattacks. Gamage seeks to create an external camera system that would capture a running visual feed of the pendulum’s motion, process those images, and use that data to balance it. “It would be robust against attacks or malfunctions,” says Gamage.
