﻿TOP 6 Fastest Robots In The World | Guinness world records
On average, a human can run approximately 12 to 15 mph -- not bad if you're chasing down an
errant Frisbee on a Sunday afternoon. But what about during an emergency? In moments like such,
speed can often mean the difference between life and death. Add 60 pounds of protective gear and
equipment that first responders often wear and speed and agility become a sluggish after thought.
Is there anyone -- or anything -- else to turn to for a speedy rescue? Keep watching!
Hi! My name is Alex and welcome to Al News Daily. In this video, we bring you the top 6
fastest robots in the world today! Don't forget to subscribe and turn on the notifications.
Let's get started! Number 6. Cheetah, 28.3 mph
Developed and tested by Boston Dynamics for DARPA's Maximum Mobility and Manipulation
(M3) program, Cheetah had already worn the crown of world's fastest robot with a land
speed record of 18 mph. However, records are made to be broken and, recently,
Cheetah did just that when it was clocked at 28.3 mph on a treadmill, thus trumping Bolt's top speed
by .51 mph. One big difference, though: Cheetah is tethered over a treadmill. "My take on speed is
that we are not trying to achieve extraordinary speeds, just trying to get legged robots into
the speed range of other normal vehicles," Marc Raibert, president and founder of Boston Dynamics,
wrote in an email to media sources. Similar to its animal inspiration, the Cheetah's
back flexes back and forth like an accordion which increases its stride and running speed.
"What DARPA is doing with its robotics programs," explained DARPA program manager, Dr. Gill Pratt,
in a press release, "is attempting to understand and engineer into robots certain core capabilities
that living organisms have refined over millennia of evolution: efficient locomotion, manipulation
of objects and adaptability to environments." Later this year Boston Dynamics plans to
start testing a free-running version of Cheetah capable of operating on natural terrain.
Number 5. Planar Biped, 13.1 mph Young MC wasn't the only one busting a
move back in 1989. So was a posse of engineers and roboticists from MIT's Leg Lab who were busy
creating a running man of a different sort: the Planar Biped. The Planar Biped was programmed by
Jeff Koechling -- now a chief scientist at Boston Dynamics -- when he was working on his PhD thesis
on the limits of robot running. The machine had two telescoping legs connected to the robot's
body by pivot joints at the hips. Within each leg was a hydraulic actuator that worked together with
springs to change the length of the robot's leg as it ran along its circular, boom-mounted path.
Algorithms used to control the Planar Biped focused on operating
one leg at a time. Because the idle leg was kept short until it sprang into action,
the robot ran with an alternating or hopping gait and could even do flips. The engineers
used what they learned from the Planar Biped to improve legged robots that followed.
Number 4. Legged Squad Support System (LS3), 7 mph
With speeds topping out at 7 mph on flat surfaces, you may think you could outrun the LS3, but
we'd think twice before challenging this robot to a race. For starters, to be fair, you'd need to
strap on a 400-pound back pack, because that's how much weight the LS3 has been designed to carry.
Developed for DARPA by Boston Dynamics, the untethered, hydraulically powered four-legged LS3
is designed to use computer vision, sensors and GPS to follow soldiers on missions as
a robotic pack mule of sorts. It's capable of relieving the squad's physical strain and fatigue
by carrying over four times the weight of what an average soldier carries in gear. As the LS3
trots along over rough terrain, designers envision it will integrate with troops and
interpret verbal and visual commands similar to how a trained animal interacts with its handler.
Additionally, the LS3 could be an auxiliary power source, capable of recharging batteries for radios
and hand-held devices. Three levels of sensors make up the LS3's head and allow the quadruped
to track its leader and other objects from as far away as almost 100 feet. In the bot's robust
body is the engine, cooling fans and cargo areas for gear. The LS3 may not have the physique of a
sprinter, but what it lacks in speed, it makes up for in brawn. If Aesop's fable "The Tortoise and
the Hare" taught us anything, it's that sometimes 'slow and steady' wins the race.
Number 3. MABEL, 6.8 mph With a peak speed of 6.8 mph,
MABEL is thought to be the world's fastest bipedal robot with knees. Like a human, it has a heavier
torso with light, flexible legs equipped with springs. And as a result, it has a MABEL's
remarkably human-like gait. "MABEL has large springs for energy storage," said Jessy Grizzle,
Jerry and Carol Levin Professor of Engineering at the University of Michigan. "They act like tendons
in the human body, absorbing energy at leg impact and releasing energy when the robot is launching
itself into the flight phase of running." MABEL was built in 2008 in collaboration with Jonathan
Hurst, who then was a doctoral student at the Robotics Institute at Carnegie Mellon University.
In the meantime, Grizzle and a variety of doctoral students from University of Michigan's Control
Systems Lab have spent the last 4 years tweaking feedback algorithms to keep MABEL balanced while
navigating its environment. Like a human runner, MABEL stays in the air for 40 percent of each
stride, giving it the kind of gait suitable for speed. But not just speed for speed's sake. "We're
really concerned with creating a rescue robot -- something that can go in a scenario where humans
are working in a factory or living in a home, etc., and there's been a dangerous situation,"
Grizzle said. "There's a reason fireman don't show up on horses when they go into a home or factory
because quadrupeds can't maneuver well in environments designed for upright walkers."
MABEL was also funded by DARPA, along with the National Science Foundation. Grizzle and Hurst,
now an assistant professor at Oregon State, are currently working on a robot that, unlike MABEL,
will be untethered. Number 2. PETMAN, 4.4 mph
If MABEL left you spell bound and unable to run, get a load of PETMAN's stride. You'll be so
mesmerized by it's natural human-like gait that it'll be able to outpace you just but walking.
Designed and fabricated by Boston Dynamics for the US Army and DARPA, the Protection Ensemble Test
Mannequin is an anthropomorphic robot used to test clothing worn by soldiers for protection against
chemical warfare. Standing nearly six feet tall and weighing 180 pounds, PETMAN's top speed is
4.4 mph, which made it the fastest bipedal robot in the world before MABEL came along. But speed
almost plays second fiddle to the tethered robot's other talents. Thanks to hydraulic actuation and
legs equipped with shock absorbers, PETMAN can move freely, walk, crawl, do squat thrusts,
perform suit-stressing calisthenics and balance itself on two feet when shoved. So if keeping
pace with the machines has left you so frustrated you're thinking about pushing them off the track,
take a cue from PETMAN -- the robots are just going to land back on their feet.
Number 1. HAMR-Jr This little robot—inspired
by insects, mainly cockroaches—can do incredible things. HAMR-Jr can just about squeeze onto the
surface of a penny and weighs far less than a paperclip. But don’t let its size fool you.
This four-legged robot can also carry up to 10 times its own weight in cargo and hits top
speeds that, for its size, are comparable to a cheetah bounding over the Serengeti.
HAMR-Jr can turn right and left and even scoots backward. It also runs at a pace
of nearly 14 of its own body lengths, or about one foot, per second. For comparison, cheetahs,
the speed demons of the mammal world, sprint at roughly 16 body lengths per second. HAMR-Jr
is just the beginning, the makers have added. Engineers could, theoretically, use his team’s
same methods to make even more petite robots—the size of a pencil eraser or smaller.
