Pleo is a robotic dinosaur designed to emulate the appearance and
behavior of a prehistoric animal. It was designed by Caleb Chung,
the co-creator of the Furby. Each Pleo would learn from its
experiences and develop an individual personality.
The Pleo was unveiled in
2006 at the DEMO Conference in Scottsdale, Arizona by the UGOBE
company and was
expected to come on the market around Fall 2007. Pleo shipments
started on December 5, 2007. In
2009 it was purchased by Innvo Labs. It has since been
completely redesigned and upgraded with many improvements.
was originally engineered by a group of robotic specialists, animators,
technologists, scientists, biologists, and programmers. The
design combined sensory, articulation, and neuronetics to
create a lifelike appearance with realistic movement and
The robot is software-upgradeable via
SD card or USB interfaces. In a 2008 test of various animatronic
animal toys in Slate magazine, the Pleo was the only contestant
which was considered a success, whereas the remaining models of
earlier or competing developers were mainly considered unnatural,
creepy or simply unconvincing.
