Magnus Egerstedt thought his robot would survive a few months. That was the goal when he and his team of Georgia Tech College of Engineering students installed their three-foot SlothBot in the Atlanta Botanical Garden’s tree canopy in May of last year.

But soon, the hot summer days gave way to cooler temperatures and the machine found itself amid leaves colored by fall. SlothBot would successfully endure Atlanta’s chilly winter nights and managed to hang around for its first birthday in the spring. Finally, 13 months after it went up, SlothBot has come down.
