Roboticists at UC Berkeley have designed a small robot that can leap into the air and then spring off a wall, or perform multiple vertical jumps in a row, resulting in the highest robotic vertical jumping agility ever recorded. The agility of the robot opens new pathways of locomotion that were not previously attainable. The researchers hope that one day this robot and other vertically agile robots can be used to jump around rubble in search and rescue missions.

Duncan Haldane, a robotics Ph.D. candidate at UC Berkeley, led the work. Haldane is a student in the Biomimetic Millisystems Lab of Ronald Fearing, a professor of electrical engineering and computer sciences.

To compare the vertical agility of robots and animals, the researchers developed a new metric to measure vertical agility, defined as the height that something can reach with a single jump in Earth gravity, multiplied by the frequency at which that jump can be made. Salto’s robotic vertical jumping agility is 1.75 meters per second, which is higher than the vertical jumping agility of a bullfrog (1.71 meters per second) but short of the vertical jumping agility of the galago (2.24). The robot with the second highest vertical agility that the team measured is called Minitaur (1.1 m/s).

“Developing a metric to easily measure vertical agility was key to Salto’s design because it allowed us to rank animals by their jumping agility and then identify a species for inspiration,” said Duncan Haldane, a robotics Ph.D. candidate at UC Berkeley, who led the work. Haldane is a student in the Biomimetic Millisystems Lab of Ronald Fearing, a professor of electrical engineering and computer sciences.

SALTO weighs 100 grams (3.5 ounces), is 26 centimeters (10.2 inches) tall when fully extended, and can jump up to one meter. Salto’s maximum jump height was roughly 1.008 meters (3.3 ft). For the wall jump, Salto attained an average height gain of approximately 1.21 meters (3.97 ft). Other robots can jump higher than Salto in a single leap. For example, TAUB, a locust-inspired jumping robot, can leap to 10.5 feet (3.2 meters) in a single jump.

Feb Vel says:

so you wanna search and rescue by jumping around on top of the rubble? what part of search and rescue maneuver is this? good robot, but search and rescue with this, Nah.

Luiz Henrique says:

So… For what?

True Tech says:

Trumps wall idea wouldn't stop these. Its only a matter of time before the Mexicans make these too, send them over the wall, then back again after a days work.
Might as well scrap Humpty Trumpty's Wall of Bigly Narcissism.

MassDynamic says:

now if that robot does some consecutive wall jumps, i'd be impressed. give it a sword and a shield and it'll become Link.

Ele salta muito alto noss


Incredible !!

Que ni nada de salto y decir esas weas, salto es saltar y punto.

Can Salto land ?

nice video bro and good Invention i like this video

This is amazing

thetruereality says:

Good experiment

Not a Pro says:

How about not showing the bot how and where to jump but making him able to do that itself without any preplanning and maps like a real-time parkour?

Jolly Jack says:

at least a scientist could have finally said here the truth – FFS! – that IN GENERAL it follows from the first principles that the HEIGHT of a jump achievable by a being does NOT depend on its size, more or less. a human, a salto, or a tick, all jump to about the same height, give or take. so the amazement at the height of its jump is entirely misplaced.

We can bring back dinosaurs, with robots

Fun fact salto in greek means "jump"

mentilly all says:

So fucking unbelievable that it literally gets taught that there's no Designer, meanwhile all the time some of the world's most technologically advanced companies copy "their" designs from all sorts of different complex mechanisms we find in nature…

Some people do not allow themselves to even objectively consider God's existing, to the point of self-brainwash with blatant illogic

salto means backflip in indonesian

Georgie Thumbs says:

I'd hate to see the kind of shit that is going to be going on 100 – 200 years from now, that's if humanity doesn't destroy itself first. Robots with super intellect that can out think you, out maneuver you, basically completely f*ck you up as if you were a cat toy.

Milton Lopez says:

I like this lots of potential open possibilities for create a unit that will carry a human on any terrain this ability together with a bypedal walking can be real good

Mate Varszegi says:

how can u mount guns on it, oh it's not darpa?

Вот где маргинал учится бля

I don't see this project going anywhere

gen unsaved says:

That was a child now lets try a 6ft tall man and your robot would be nothing but shit

foxy the pirate [ nathan warnack] says:

Yeah, but can it land?
