  • So every day we asked robots to do amazing things like Pick up this apple, for example and you can see this robot does this quite easily.

  • But the fact of the matter is, while robots are very good and very efficient for many tasks, we still struggle.

  • Getting robots toe handle soft, delicate items.

  • This has been a major focus of research for many, many years, and the result has really been countless damaged items, tourney fabric and crushed tomatoes.

  • So why have we struggled with this?

  • Have we been using the wrong inspiration?

  • Think about the human hand.

  • One.

  • The most complex structures in the world.

  • 29 individual bones 34 muscles 48 Identifiable nerve pass, all connected to the most complex computer in the world.

  • The human brain.

  • We've spent decades trying to recreate a robotic version of the hand, and we continue to be frustrated.

  • But is there better inspiration?

  • Should we be looking elsewhere in nature?

  • Are there things that can grass objects do complex manipulations similar to the human hand, but maybe or less complex to recreate?

  • Let's think about the Octopus.

  • The Octopus is very good at manipulating items and octopus tentacle can easily wrap around at item, conform to it and grasp it.

  • The octopus can do some of the most compartment of manipulations we've seen in the world, so why don't use The Octopus is the inspiration and see if we can solve this problem.

  • That's exactly what a group of researchers at Harvard University did in 2000 and nine.

  • They set out to create a robotic version of The Octopus.

  • But instead of employing the traditional toolkit of motors and sensors and rigid linkages, they look to material science.

  • And what they found is by creating layers, composite material structures, using rubber and paper and embedding microphone tick channels into these structures.

  • They could get these devices toe, act like an octopus tentacle.

  • Think about it.

  • Robotic programming through origami.

  • Once you build a composite, you embed the patterns.

  • You apply pneumatic pressure.

  • Now you have something that acts like a octopus tentacle, deforms, conforms and safely grasp an object, and that's exactly what they've done.

  • So let's take a look at how it actually works, so there's some difficult objects out there.

  • If you think about this bath sponge, it's a very simple object for a human being to pick up.

  • But it's soft.

  • It's light, it's fluffy.

  • It's unstructured, a real challenge for a robot, so you can see we'll set it down and let the octopus tentacles do the work.

  • So continuing at the bath theme, a child's toy a bath doc once again, a very simple object for human hand to manipulate but until recently, impossible for a robot to handle.

  • So let's see how I robot does with this once again simple object for humans, an easy object for an octopus.

  • Now we could enable this manipulation very easily.

  • In the last item something is delicate is an English breakfast scone that I picked up this morning.

  • We can set this down and once again, through material science, were able to pick it up and manipulate it without damage.

  • And yes, indeed, this is actually a crumbly scone that I can pull apart.

  • So what's important here is how does this work?

  • That's probably the question you're asking right now is how does this work?

  • In a normal robotic situation, we'd be stopping the robot between every item in reprogramming.

  • We'd have to know the mass of the object.

  • These excise the object.

  • The center of gravity object and programmed a robot to apply just the right amount of force you can clearly see on stage.

  • There's no cameras here.

  • There's no sensors at work.

  • There's no artificial intelligent lurking behind the robot knowing how to pick these items.

  • The robot has no idea which items it's picking.

  • The only thing at play here is material science.

  • So why is this important is we have industries that need robots that need robotic hands, but we have not been able to automate to date.

  • So think about agriculture, food and beverage manufacturing.

  • Some of the task in advanced manufacturing with advanced materials are even handling retail, e commerce or grocery logistics.

  • These air all task that have been closed automation because this grasping problem.

  • But now we can enable that.

  • So let's think about the future.

  • Where do we want robots?

  • We want robots to help us in the home.

  • We want robots to help us in the office, but think about the multitude of items that we interact with in our day to day, whether it's at the office at home or walk through the supermarket off.

  • Think about something as simple as the chicken's egg.

  • This is something that if we want the robot to cook his breakfast, it's going to have to be able to manipulate a chicken's egg and do it in a way that we make sure that it gets to the right place and it's safe and sound is it's done.

  • So I know the question you're asking.

  • Is it?

  • Is it a hard boiled egg?

  • You can see it's clearly a raw egg, so now we can take robots where we need them into automation, into the home into these areas.

  • But can they do these really difficult task?

  • Could one day robots pick tomatoes from the violin for us?

  • As you can see, the answer is plainly.

  • Yes, thank you.

So every day we asked robots to do amazing things like Pick up this apple, for example and you can see this robot does this quite easily.
