Slow, risky 3D navigation (1 MIPS)

A mainframe PDP-10 computer allowed the Stanford "Cart" mobile robot to interpret stereo images from a sliding camera into sparse 3D maps of about 100 visually distinctive features, to localize its motion and identify and avoid obstacles on its path. It paused to glimpse and compute about 10 minutes for each meter of travel, and became navigationally confused about every 20 meters. The controlling program was developed from 1974 to 1979.
