Kilobots — Cheap Swarm Robots Out of Harvard 121

Posted by Soulskill from the keep-wil-wheaton-away-from-these dept.
An anonymous reader writes with news of a research project at Harvard into controlling large swarms of small robots. This article describes what they call Kilobots. (Which, for clarity's sake, have nothing to do with killing. Yet.) Quoting: "They're fairly simple little robots about the size of a quarter that can move around on vibrating legs, blink their lights, and communicate with each other. On an individual basis, this isn't particularly impressive, but Kilobots aren't designed to be used on an individual basis. Costing a mere $14 each and buildable in about five minutes, you don't just get yourself one single Kilobot. Or ten. Or a hundred. They're designed to swarm in the thousands."

      Good question. Also, you'd have to find a well-cleaned aircraft hangar or something with enough perfectly flat, obstacle-free space for them to do anything. I don't think the idea is really about making these particular ones practical... but more about programming a whole swarm all at once and having them ready to go off and do whatever they're supposed to on their own. And managing that in a way that's cheap and effective. The article says they're looking to get up to a thousand of them and have them work out "self healing" and "collective trasport". These taks have been done individually, but baby steps towards a more impressive whole, I guess.

    I understand that small steps (no pun intended) need to be taken to advance the state of the art, but this remains an academic novelty until these little guys can do something useful. Doesn't have to be terribly complicated. There are plenty of simple yet highly repetitious and tedious tasks that would be perfect for a cooperating swarm of little worker bots working in parallel. Like carrying the leaves off of the lawn and depositing them in the woods (or a recycling bag) in the fall or similar. Then I would be impressed (and would be the first in line to buy the kit).

      For you and I further down the food chain, it'll probably be a while. For researchers, though, it's arguably already useful. FTA:

      Generally people who want to experiment with large swarms have had to be content with computer simulations, which is fine, but at some point you have to try things out in the real world (or as close as you can get in a lab), and Kilobots can make that happen. .. at $14 each, a thousand robots is actually an achievable number with a modest grant, which is something that probably has not been possible before.

      • Agreed. I made a weak attempt to acknowledge this in my opening sentence, but in my haste to get to my main point, I was overly dismissive without meaning to be. Moving beyond simulations and into the real world is definitely a necessary and laudable achievement.

    • Exactly. Clean out my gutters. Paint my house. Weed my garden. Stop just writing papers.

    • From a military or industrial perspective, this is useful. This is one step away from a self-organizing mine field, or sensor array. By allowing them to choose the proper *scatter*, you can very easily release a set of bots in the field to do anything from look for oil in the water to finding illegal aliens crossing the border. True, these little guys are not going to be the used solution, but they are providing the conceptual testing that will lead to more expensive and larger machines doing real work.

  • Swarm behavior requires a mutual awareness between devices. This is simply a remote control which affects a large number of units. The problem with this approach is that it only works initially, but random differences in movement become magnified over time. Since each bot movement includes a random margin of error (think: drunkard's walk) the "swarm" will dissipate over time and show less cohesion. In true swarm behavior, each individual actor (bot, in this case) is aware of the greater swarm.
