SlothBot is a solar-powered, cable-driven, environmental monitoring robot. It is designed to be present in natural ecosystems, primarily under tree canopies, over long periods of time without any human intervention while measuring microclimate data. It's cute and slow—very slow.

The SlothBot concept was envisioned during a vacation trip to Costa Rica where there are actual sloths everywhere.
SlothBot was developed at Georgia Tech, in Atlanta, by Magnus Egerstedt, a professor of robotics who led the project; Gennaro Notomista, a PhD student; and a team of engineers and ecologists. They were inspired by sloths they saw in Costa Rica. The sloths gave them the idea of exploring "slowness as a design paradigm" through an arboreal robot. Egerstedt is now a professor of electrical engineering and computer science and dean of engineering at the University of California, Irvine. Notomista is now a professor of robotics at the University of Waterloo in Canada.
