Ant robotics
Invented by – James McLurkin
While working at the Massachusetts Institute of Technology's Computer Science and Artificial Intelligence Laboratory in 1991, American electrical engineer James McLurkin was the first to propose the concept of "robot ants." Sensors, infrared emitters, and communication systems equipped the robots to detect objects in their route. Swarm robotics is a subset of ant robotics. Swarm robots are rudimentary machines with limited sensing and computing skills. Ant robots are swarm robots that communicate by leaving and following pheromone trails, much like ants do. Some ant robots utilise long-lasting trails (normal chemical trails or smart transceiver trails), while others use short-lasting trails (heat, odour, alcohol, or light), and still others employ virtual trails.

There were no computers that were entirely electronic. Industrial printing presses were the only printers available. HP's innovations were essential in making home computers and printers more affordable for the typical customer, and their success prompted a flurry of electronics startups in Santa Clara County, California.
