The P series is a series of prototype humanoid robots developed by Honda between 1993 and 2000. They were preceded by the Honda E series (whose development was not revealed to the public at the time) and followed by the ASIMO 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.
