This Day:

Robots have a big step at kicking us humans into the dustbin of history;);). They have learnt how to catch!! A robotic catcher, developed by scientists at the University of Tokyo, Japan, can comfortably grab a ball careering through the air at 300 kilometres per hour, or 83 metres per second, according to its creators, Akio Namiki and his colleagues:).

he robot does not even need a catching mitt. It resembles a single metallic claw, with just three fingers instead of the human complement of five. An array of 32 by 48 individual photo detectors in its “palm”, tracks a ball's trajectory at high speed. And a series of specialised image processing circuits recognise this movement almost instantly.
An approaching ball triggers the robot's three fingers into action. Actuators embedded in each joint use a burst of high current to move through 180 degrees in less than one tenth of a second. This enables the machine to snatch the ball in the split second it takes to arrive.
A video of the robotic hand catching the ball can be seen here:):).

Just been reading about this.

Quite cool.

Like one guys said, it's more of an engineering novelty right now, with no immediate practical use.

But I'm sure if I think about it for a while, I'll come up with a suitable application for the thing...

Many good things start that way, without a priactical use... but soon find really cool applications.

Heyy, I am seeing u here after a long time! Welcome back :).

I've been busy.

While there's no doubt that what these guys have done is pretty good, it's nothing new.

There's a laboratory at MIT where they have pair of robotic arms and a couple of cameras placed loosely where a head might be.

All this thing does is sit there and wait for something to be thrown at it.

So in many ways, the only thing unique about this recent device is the speed at which it can catch items, given that it's stationary...

I guess Indian cricket team might find it very useful. They could attach it to their hands and then could stand in the slips so that no knicked ball goes by uncaught...see I found an application just now :D... japanese are really crazy..i dont know where will they take up technology too...:D

Wayne: I agree. But the speed is an important thing! The next step would be to put it on top of a moving hand, and who knows, perhaps we can have a tennis player :D:D.

Abnegator: sure they can :)).. but I am sure they will find a way to drop the ball then too :D.
