Comment Slop merchant promotes slop (Score 4, Insightful) 97

You have to eat the slop we created because you have no choice. We now have a vast slop content machine that cost us a lot of money and we will make a profit no matter what. We don't care if the slop is toxic and poisons you and degrades everything it invades. There is no red pill option. You only exist to monetize our investment. Shut up, open you mouth, and start gulping.

Kilobot 2012

The Kilobot is a 3.3 cm tall low-cost swarm robot developed by Radhika Nagpal and Michael Rubenstein at Harvard University. They can act in groups (over a thousand), to execute commands programmed by users that could not be executed by individual robots. A problem with research on robot collectives is that the cost of individual units is high. The Kilobot's total cost of parts is under $15. In addition to low cost, it has applications such as collective transport, human-swarm interaction, and shape self-assembly.

The power source is a rechargeable lithium-ion battery that can power the robot for up to 3–12 hours depending upon how active the robot is. They are equipped with a three color (red, green, and blue) LED which displays information to the user. While wheels are effective at movement, they are expensive, which substantially increases the cost of each unit. One way the cost was lowered was using two vibrators for movement. When either is activated, the Kilobot turns at about 45 per second. When both are activated, the robot moves forward at about 1 cm/s. The robot stands on 3 rigid legs, which elevates the robot 2 cm above the surface. The individual robots are equipped with an infrared transmitter and receiver so that they can communicate with each other. The transmitter of a robot sends light toward the surface which reflects up to the receiver of another nearby robot, which then executes a command based on the program. Some drawbacks of these methods of communication and movement are: the area on which the Kilobot works is limited to flat surfaces and the inability to move precisely over long distances or over an extended period of time.

Obviously only useful in a lab setting, but still a physically realized example of swarm robotics over 12 years ago.
