The project has produced robots which are able to learn mobility, progressing from basic crawling to stair climbing. Although hundreds of robots have been constructed, the most notable include Elvis, Elvina, and full-size humanoid Priscilla. Elvis was the first humanoid robot used in Sweden in advanced AI / robotics research in The Humanoid Project on self-developing robotic control. The robot hardware was conceptualized and designed by Marcus Tallhamn and Manne Kihlman. Priscilla was the first full-size humanoid robot created in Sweden.
^Elvis, Elvina, and Priscilla as well as ideas and science of the project (along with other robots and other research) are discussed in the Swedish popular science book; Humanoider: Självlärande robotar och artificiell intelligens (Humanoids: Autodidacticrobots and artificial intelligence).
