Creepy Tentacle Robot Can Carefully Grasp Fragile Objects

Because what good is a robotic gripper if it breaks everything it touches, researchers at Harvard’s John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a robotic gripper that can carefully grasp and pick up objects with its creepily long tentacles. Just imagine that thing slithering up your pant leg!

Drawing inspiration from nature (specifically octopuses and jellyfish), the SEAS researchers created a soft gripper that uses thin tentacles to “entangle and ensnare object, similar to how jellyfish collect stunned prey.” A rather unsettling image when applied to robotics. The tentacles are powered by air alone and don’t require any sensing, planning, or feedback control to operate. The individual pneumatic tentacles contract when air is removed, causing them to curl up and grab any objects they run into. Again, unsettling.

Fine, but if these things make their way to the doctor’s office, you can count me out. I can’t help but play with all the equipment after the nurse leaves, and I’m waiting for the doctor; there’s no telling what sort of trouble I’ll get into with one of these. I really don’t want to have to change doctors again.

MIT robot’s flytrap gripper can grab both fragile and heavy objects

Robot hands tend to skew toward extremes. They can pick up delicate objects or heavy objects, but rarely both. MIT CSAIL's solution? Avoid hands altogether. Its researchers have developed a Venus flytrap-like gripper that can grab objects as frag...

The next robot crawling through your gut could be a gummi bear

The future of robotics is decidedly squishy. We've already seen gel-based 'bots that can catch fish, mimic octopi and even ones that can keep your heart pumping. And, if the researchers from Switzerland's EPFL are successful, they could soon be crawl...

Soft Grip Robot Fingers Can Lift Eggs without Cracking Them

I want a robot in my house that can clean, cook, and do laundry. That will free me up to watch movies and play Fallout 4. The catch is that robot hands today can’t really pick up fragile items like eggs, and if the robot can’t make bacon and eggs, it’s pretty much worthless to me.

Fortunately, scientists have created a new robot hand of sorts that can handle fragile and delicate items like eggs. It’s not the first soft robotic gripper, but it improves upon prior designs.

Researchers at the Ecole Polytechnique Federale De Lausanne (EPFL) developed a soft robotic gripper made using electrode flaps. The flaps are made of five components, including a pre-stretched elastomer layer with two layers of electrodes, and two outer layers of silicon of different thicknesses. When voltage is applied, the flaps curl inwards to grip. When voltage is removed, the flaps curl outwards.

The lightweight gripper also uses electrostatic grip, this is what makes a balloon stick to a wall if you rub it on your head. The result is an ability for the flaps to lift up to 100 times their own weight and handle delicate objects without needing to know the shape of the object beforehand.

We are now one-step closer to an omelet-making robot that won’t get shell in my eggs.

Willow Garage may sell its Velo robot gripper early, if you ask nicely

Willow Garage may sell its Velo 2G robot grippers early, if you ask nicely

Some have called Willow Garage's health into question lately, but the company may have a minor hit on its hands -- if through an unexpected channel. The firm has seen a strong enough response to its Velo robot gripper that it's mulling an early sale of the device this fall, at an educational price somewhere between $500 and $1,000. Whether or not that happens depends on feedback, however. Willow Garage is both offering notification sign-ups and running a feature survey -- if you need a different interface or better performance, now's the time to speak up. There's no guarantee of receiving a Velo when the company might ship just 50 to 100 of the advance units, but you won't get one if you don't ask, will you?
