TheP series is a series of prototypehumanoid robots developed byHonda between 1993 and 2000. They were preceded by theHonda E series (whose development was not revealed to the public at the time) and followed by theASIMO series, then the world's most advanced humanoid robots. Honda Motor's President and CEO Hiroyuki Yoshino, at the time, described Honda's humanoid robotics program as consistent with its direction to enhance human mobility.
Work to develop an advanced humanoid robot began in 1986, when Honda established a research center focused on fundamental technologies, including humanoid robotics.
Honda engineers had to research how humans walk, using the human skeleton for reference to create a replica and have it function like a human being. In 1986, the first two-legged robot was made to walk, used by Honda engineers to establish stable walking technology, including steps and sloped surfaces.
In 1993, Honda began developing "Prototype" models ("P" series), attaching the legs to a torso with arms that could perform basic tasks. P2, the second prototype model, debuted in December 1996, using wireless techniques making it the first self-regulating, two-legged walking robot. P2 weighed 463 pounds with a height of six feet tall. In September 1997, P3 was introduced as the first completely independent bi-pedal humanoid walking robot, standing five feet, four inches tall and weighing 287 pounds.[1]
Honda engineers determined a robot should be easy to operate and small in size, enabling it to help people—for instance, to look eye to eye with someone sitting in a chair.
ASIMO can be controlled by a portable controller whereas P3 was controlled from aworkstation.
