Robot Hand Can Sense Objects Before Touching Them
Posted by Adrian Covert at 1:26 PM on June 12, 2008
Over at Intel's R&D fair, Wired got to play with a robot hand that is able to sense an object it's about to come in contact with before actually touching it. Using electrolocation, the fingertips of the robot hand send out a weak electrical impulse, and approaching objects interfere with that impulse, which allows the hand to form to the object before touching it.
The ultimate goal for Intel researchers is to give robots the sense of pre-touch, which they describe as having a range longer than touch, but shorter than vision (kinda vague, no?). Anyways, the video is worth watching, just to see the claw adjust to objects placed within its proximity. [Wired Science]

@skittlzncombos: LOL! It will exactly like the real thing!!
I love the robotic voice in the clip; "oops. I can't grab it. "! Might go with the bot for some...

We can do this ourselves in a way. You can feel when your hairs stand on end due to being brought near something with an electrical charge, and of course we can feel whether an object is hot or cold without touching it.

Great, now my sex bot will know I'm trying to touch it, and know when to pull away. Dammit.

I am trying hard to think of a funny reference to not being able to grab things, but I just can't do it.

@Elliuotatar: Sometimes I think it's more than that. I, and I'm sure many others, can usually sense the presence of somebody walking in a room or standing behind them whether or not they actually hear them. It's also never failed that the other person I am looking at on the freeway usually turns to acknowledge my passing interest which is especially comical when they have their finger up their nose (as I so often do).

@portugue: I was thinking more along the lines of there now being something one step above the left hand, but yeah, that wouldn't apply to pre-touch sensitivity.

No one else thought of the greatness of a claw machine game incapable of loosing? Well.. great for those of us who can never get that kushy batman pillow! Kyar..

Just another thing to fear when the robots uprise.

"pre-touch, which they describe as having a range longer than touch, but shorter than vision"
very oddly put, but i dont see how its vague. you can see things coming, but you cant really "sense" them (unless you count hearing and maybe goose bumps). So basically, since the robot has no eyes, it cant see that you are standing 10 feet away. However, once you get within a few inches, it does its magic, recognizes ur precence, and acts accordingly
you know i wonder if there really is a chance that we'll wind up going to war against robots....

This is pretty cool - like how sharks and other fish can sense electric fields in water. I could even see this being specialized to aid in determining the proper strength of the actual grip part; the sensors figure out what type of object is nearby according to its conductance (or lack thereof) and tell the hand how hard to grip.

@Dapole: looking back, really not that funny, but cut me some slack. I may or may not have had a few, and just finished a Cognitive Neuroscience final and had a Econometrics final earlier in the day... So my brain is a little fried.

Happens to the best of us... Occasionally.. Ok more then i'd like to admit... Don't look at me, im a monster!!!

@Dapole: They tried to teach us the econometric system in school, but it didn't take. :(

@shamoononon has a hebetudinous dog:
I'm pretty sure that people notice your passing interest because we have peripheral vision, and even though we can't conciously make out any details in our peripheral vision, there must be enough details there for our brains to subconciously tell that there is a face looking at us.
