Engineers Use Laser Pointers To Guide Household Robots

The New York Times is running a story about a recently developed technique for directing the actions of household robots. Engineers from the Georgia Institute of Technology have created a robot that will fetch items for you by simply shining a laser on the desired object. Quoting: "'The pointer gives the robot just enough context and guidance to solve the really hard problem of figuring out which object among many lying around in a room to pick up,' Professor Sukhatme said. 'People in artificial intelligence have been working on this problem for a long time.' Just pointing to an object with natural gestures usually isn't enough to direct a robot, and even when robots navigate to the right spot, it's hard for them to grasp a particular object unless, for instance, they have a three-dimensional computer model of it, Professor Kemp said. Guided by the laser pointer, though, El-E can fetch objects as varied as towels, wallets or coffee mugs with no need for elaborate computer modeling."

Took them long enough ...

Get the Aibo!

WARNING: Do not try with airplanes, helicopters, or police cars.

They will justify the millions of dollars they spent for the patent too.

It's hard to replicate thousands of years of evolution, unfortunately.

Actually, entertaining your cat with a laser pointer is patented (no joke) so they had to find something else to play with.

Hrm... wouldn't this just be a consumer version of laser targeting systems that's been used by the military for aiming missiles at buildings and stuff?

Well, I for one welcome our new laser-guided missil^W^H robots.

Re:

What you say is indeed true, but they have found a way to target individual objects without the requirement of complex vision systems. This might be a step forward in several areas of robotics. If you have a robot that is traveling back and forth in a hospital carrying supplies to various points, having to identify each parcel or tray with tags is complex. It would be much easier to do this in some universal way, and laser tag might be that way.

In general, it is not much good for a roomba unless you are usi

Re:

[sholden]

It's a different problem/solution. Vacuuming a room is something that can be done petty much independently, it's a problem of navigating around obstacles and so on. Telling the robot to pick up object X over there has the additional step of communicating which of the objects X is and then the robot can do the navigation steps.

This is hard enough with people "could you grab the remote for me? No not that one, the one to the left. No the other left. No the big one with the green button at the top. No. No. Yes

One thing that people aren't realizing is that some people simply cannot "fetch" things for themselves. I'm talking, of course, of paraplegic and quadriplegic individuals. People have trained monkeys [monkeyhelpers.org] for this purpose, but having a pet monkey is stressful even for the able bodied [nationalgeographic.com]. So a bot that can do this would be a blessing. A quadriplegic could have the laser pointer on a headband and point with it using their head.

Re:

From the National Geographic article you linked to:

No federal laws regulate private ownership, and only nine states ban individuals from owning nonhuman primates.

So, one cannot own nonhuman primates... Human primates are okay to own, though?

Sorry, coldn't resist trying to be funny.

Only in certain Muslim countries: Saudi Arabia, Sudan, Mauritania.

Re:

Quadriplegics with lasers on their heads?

I dunno, I think sharks are cooler.

Also, for those who have RTFA...

[MsGeek]

Doesn't this robot look like HELPeR, the robot from The Venture Brothers? :-)

So...

[everphilski]

So they've implemented semi-active laser [defense-update.com] guidance. Not exactly revolutionary, we've been doing it in missiles for years ...

Yes, well, there's a difference between "pick something up" and "blow the fuck out of it." Still, sometimes a little cross-fertilization between disciplines comes up with some useful results.

I can do the same thing with cats.

Re:

[tomhudson]

I can do the same thing with cats.

... but now you can do it with your Roomba ...

Better option: Tape the laser pointer to the Roomba, and have it drive your cat nuts.

Sure, good news, but...

Makes sense. Keep it simple...
