The Johns Hopkins Beast used to be a cellular automaton, an early pre-robot, in-built the 1960s at the Johns Hopkins University Utilized Physics Laboratory. The machine had a rudimentary intelligence and the ability to survive by itself. As it wandered by the white halls of the laboratory, it may per chance per chance per chance per chance gape dark wall outlets. When it found one it may per chance per chance per chance per chance bound in and recharge.
The robot used to be cybernetic. It did no longer employ a computer. Its modify circuitry consisted of dozens of transistors controlling analog voltages. It venerable photocell optics and sonar to navigate. The 2N404 transistors were venerable to invent NOR common sense gates that implemented the Boolean common sense to show it what to full when a particular sensor used to be activated. The 2N404 transistors were moreover venerable to invent timing gates to show it how long to full something. 2N1040 Vitality transistors were venerable to modify the energy to the circulate treads, the growth, and the charging mechanism.
The authentic sensors in Mod I were physical touch fully. The wall socket used to be detected by physical switches on the arm that adopted the wall. As soon as detected, two electrical prongs were prolonged till they entered the wall socket and made the electrical connection to payment the auto. The stairway, doorways, and pipes on the hall wall were moreover detected by physical switches and recognized by appropriate common sense.
The sonar guidance system used to be developed for Mod I and improved for Mod II. It venerable two ultrasonic transducers to in discovering out distance, assign for the period of the halls, and obstructions in its path. This equipped “The Beast” with bat-esteem guidance. At this point, it may per chance per chance per chance per chance detect obstructions within the hallway, equivalent to folks within the hallway. As soon as an obstruction used to be detected, the Beast would sluggish down and then objective a pair of call whether or no longer to discontinue or divert around the obstruction. It may per chance well per chance per chance moreover ultrasonically acknowledge the stairway and doorways to have interaction appropriate circulate.
An optical guidance system used to be added to Mod II. This equipped, amongst other capabilities, the ability to optically name the dark wall sockets that contrasted with the white wall.
The Hopkins Beast Self reliant Robot Mod II link under used to be written by Dr. Ronald McConnell, for the time being a co-op pupil and one of the considerable designers for Mod II.
