The Johns Hopkins Beast Circa 1960

Built during the 1960s at the Applied Physics Laboratory at Johns Hopkins 
University, the Johns Hopkins Beast was a mobile automaton. The machine had a 
rudimentary intelligence and the ability to survive on its own. 

"Controlled by dozens of transistors, the Johns Hopkins University Applied 
Physics Lab's "Beast" wandered white hallways, centering by sonar, until its 
batteries ran low. Then it would seek black wall outlets with special 
photocell optics, and plug itself in by feel with its special recharging arm. 
After feeding, it would resume patrolling. Much more complex than Elsie, the 
Beast's deliberate coordinated actions can be compared to the bacteria hunting 
behaviors of large nucleated cells like paramecia or amoebae."

"The robot was cybernetic. It did not use a computer. Its control circuitry 
consisted of dozens of transistors controlling analog voltages. It used 
photocell optics and sonar to navigate. The 2N404 transistors were used to 
create NORO logic gates that implemented the Boolean logic to tell it what to 
do when a specific sensor was activated. The 2N404 transistors were also used 
to create timing gates to tell it how long to do something. 2N1040 Power 
transistors were used to control the power to the motion treads, the boom, and 
the charging mechanism"
