Alpo
In 2001, the South Korean company ROBO3 launched Alpo, a raptor robot, which closely resembled TITRUS-III.
Alpo became a news item for being South Korea’s first two-legged walking dinosaur robot. This raptor robot is mighty in size, being 2.5 meters long with a weight of 120 lbs. It walks at a rate of 1.4 meters per minute.
Like its successor TITRUS-II, Alpo is able to sustain its balance while walking by swaying its neck and tail. This behavior is enabled by a parallel link mechanism and certain degrees of freedom, allowing its mechanical joints and motors to perform movements.
