Robots Learn To Follow

Roland Piquepaille writes "Three years after the development of robots that act like rats, UC Davis engineers have designed a control system for robots allowing them to pick up on cues that the leader is about to turn, predict where it is going and follow it. This system mimics the human ability to capture signals — consciously or not — from drivers on the road or people walking in the streets to predict what they're about to do. As the team leader said, 'Robots that are better at following could be easier for people to work with.' With this system, a hospital robot could follow doctors during their rounds."

    3. Re:Overlords by lysergic.acid · · Score: 1

      negotiating intersections is a completely different problem. all it takes to negotiate an intersection is to know the rules of traffic priority/right of way (or abide by other traffic control devices like traffic signals).

      when there's a pre-established protocol for prioritizing traffic, there's little need for complex decision-making on the part of the individual. that's the way our road systems are designed so as to minimize accidents. it may take a new driver a little while to learn these rules, but they would be very easy for a robot/computer to pick up.

      the problem arises when you have to negotiate traffic independently without a pre-established protocol. pedestrians don't follow traffic laws or pre-agreed-upon rules of priority. so you have to detect more subtle signals from each individual to predict their behavior.

      it's more like negotiating a lane-change. even though you still have to obey traffic laws, there's no strict protocol that dictates whether someone has to allow you to change lanes or not. so even after you put on your signal you have to watch nearby vehicles carefully to make sure your speed is in sync and that you won't have a collision.

      In all honesty, I think the vast majority of people are like this. German heritage only comes into play because we get raised with a perspective of strong pride in being part of well organized group rather than a perspective which values you according to how high up the ladder you are. It's a good perspective we have, because any society will need more followers than leaders (or as my first well-run programming outfit put it, "We need more Indians, not more Chiefs").

      However... the qualities that make *most* people into leaders is not their ability to lead wisely, but their ability to get others to follow, period. Which is why, if you look at all the leaders the human race has ever had, they come off as being significantly worse human beings than the ordinary people you've met in your life.

      So in all seriousness, I think we really would be better off with "Robot" leaders. Things which unquestionably accept our principles and guidelines, yet also possess the ability to get people to follow them.

      In a way, laws are like that. We have a law that says you can't murder someone unless in self defense. And if you do so, you can argue all you want that you should have been able to, but the law remains written exactly as it was as still applies to you. Sure, you change the law later, but it doesn't retroactively make what you did legal.

      The only problem with just having laws alone, is they lack the ability to get you to follow them voluntarily. So you have to create a law enforcement component. And that puts a big gap between those making the laws, and those following them - leading ultimately to bad laws. And even outside of that, someone who can get you to follow them can also get you to disregard those laws.

      Now, imagine a computer (like the one you're using or one inside a mobile robot), that had the ability to get you to follow it voluntarily. You program it with the motivation to say, induce you to complete whatever items you put on your todo list, and it essentially talks you into it. On a personal level, you'd be incredibly productive. It would be like having a boss who didn't care about his salary or the company's profits - only your personal advancement.

      99.999% of us spend our lives as "followers" in our social hierarchy. As children we do as our parents, as young people we do what our parents, teachers, and peer groups say, and after a brief debacle as college students who don't really follow anyone, we wind up as adults doing what our boss's say. In our unstructured time, we pretty much do what - sorry - marketers of leisure say. We very rarely "lead", and when we do it's a lot more difficult than following.

      I wrote a program once to manage my free time productively. When it got to the point where it was more qualified to do that than I was - it didn't matter. Because it hadn't made me feel like it's "follower" yet.

      Look at any person or group that gets people to follow. The less qualified the better. You'll see a staggeringly large amount of similarities. If we can give these abilities to machines, the ability to get us to follow them voluntarily - perhaps one day we really will have Robot Leaders. And if you're a programmer or engineer - you know that bullshit about computers randomly changing their goals to selfish ones is *never* going to happen. We programs malfunction, 99 times out of 100 they simply crash. The other time they do something clearly wrong. Ever see a spreadsheet formula get corrupted in a way that just so happens to increase the budget for spreadsheet programs? Me neither.

      The *last* thing we need is robot followers, because as a species we've consistently produced terrible leaders. But we do have very good goals (life, liberty, pursuit of happiness, protect and serve, tell the truth, the whole truth etc.) - we just need *leaders* who will follow those goals as faithfully as a computer follows it's programs.
