Self-navigating robot gets its own charge (Jan, 1965)

Self-navigating robot gets its own charge

A machine that recharges its batteries by finding and plugging into the nearest wall outlet is under test at Johns Hopkins University Applied Physics Laboratory.

Like a hatbox full of bees, it buzzes up and down a hall, probing ahead to avoid open doors, stairs, and other obstacles.

Equipped with sonar, the robot may find use in moon or undersea explorations.
