FROG is a quadruped robot that can walk, trot, and climb over obstacles. It's used as a research platform, but its creators are transforming one version into a Triceratops robot for a Chinese museum.

FROG is short for four-legged robot for optimal gait.
Dr. Wei Wang, one of FROG's creators, decided to develop the robot because his daughter and her kindergarten friends are constantly begging him to build robotic animals.

FROG was developed by Dr. Wei Wang's team at the Institute of Automation, part of the Chinese Academy of Sciences, in Beijing. The quadruped is a research platform that Dr. Wang and his PhD students use to develop and test quadruped gait control, gait transition, and other locomotion algorithms. FROG was completed in 2010, and the researchers plan to upgrade its design and also use it for applications in entertainment, for example as robotic dinosaurs at science museums.
