WASHINGTON : This leaping robot can out-jump anything — animal or machine
WASHINGTON : What’s the size of a soccer ball but can jump a distance spanning from the Statue of Liberty’s feet to her eye-level? A new record-setting robot. It soars three times higher than any other jumping robot that its builders know of. It also out-jumps any living creature.
“It is truly amazing to stand near it and see it launch itself skyward faster than you can even see,” says Elliot Hawkes.
A mechanical engineer at the University of California, Santa Barbara, Hawkes has been working on this robot for seven years. It started out as a “stick with weights and rubber bands,” he recalls. No one would have called it a robot at that point because it had no motors or electronic parts. But, he notes, it got him and his colleagues thinking, “just how high could we go?”
After years of work, the robot has reached heights of 30 meters (100 feet), Hawkes and colleagues reported in Nature on April 27.
This robot’s springy legs are made of carbon fiber, a super-strong material. Rubber bands add extra spring but also help hold the legs together. Some versions of the robot didn’t have rubber bands. These “had a bad habit of exploding instead of jumping,” says Hawkes. “The legs would break and fly into a hundred pieces!”
Powerful muscles
These researchers studied how animals jump. They looked into leaping frogs, spiders, kangaroo rats, squirrels, lizards, dogs and more. But Hawkes’ group didn’t want to copy any of these animals. Instead, the team learned what features set the limits for animal jumpers. Then, the group found ways around those limits.
In the bodies of many animals (including humans), muscles provide the energy for a jump. The muscles tug on stretchy tendons, which act like springs. As they stretch, those muscles and tendons store energy. They release it again as they snap back to their normal length. The stored energy propels the jump. Jumping higher requires bigger muscles.

But a muscle can only tense and release once per jump. So you only get one chance to crouch down in order to jump high. In a motor, this is called one stroke. Most animal jumpers develop large motors (muscles) and small springs (tendons).
Weight is another limit. Larger muscles (or motors) make something heavier. And heavier things find it harder to move against the force of gravity. “If you want a robot to jump high, you need to balance a lot of different parts,” says Cynthia Sung. A roboticist at the University of Pennsylvania in Philadelphia, she was not involved in the new study.
Stretchy springs

This robot takes off so quickly that it experiences an acceleration of 315 g — or 315 times the force of gravity. That would kill a person. But many tiny insects can endure that many g’s. The froghopper (or spittlebug) reaches 400 g when it leaps.Brian Long, Amy Hao, Chris Keeley and Elliot Hawkes
A robot jumper can use a small, light motor and a large spring. That’s because it can use a latch to keep the spring in place while the motor gradually stretches it out. With each stroke of the small motor, the spring stretches a bit more. This is called work multiplication. Even if a single stroke of the motor isn’t very powerful, its power gets multiplied over many strokes as it is stored in the spring.
Hawkes’ team used this type of system to maximize how high a robot can jump.
The new robot has two types of springs. It has legs that bend into a hoop shape. As these legs bend, rubber bands connected to them also stretch. By the time the robot is ready to jump, it has a squat, round shape. When the latch releases, the legs and rubber bands all snap back into a narrow shape similar to a model rocket. That’s not an accident: This shape will easily cut through the air.
As the springs snap, the robot shoots skyward. In just 9 thousandths of a second, it can go from sitting still to shooting upwards at nearly 100 kilometers (60 miles) per hour, says Hawkes. That amount of sudden acceleration would kill a person. When the robot lands, it can now position itself for the next jump.
Shooting for the moon
“It’s very exciting,” says Sung. She was impressed with how high the robot leapt. And maximizing height was the main goal here. However, for the robot to be useful, it will need some improvements.
“They don’t have any steering at all,” notes Sung. That means this robot can’t control its jump height or direction. Sung’s team has made its own jumping robot, named REBOund. That bot can’t jump very high. But it can be programmed to jump to any of several different heights.
Hawkes’ team is working to add steering to its robot. These researchers hope to send their robot to the moon, so they also want to find a way for it to collect samples. A jumper can go places a robot with wheels can’t. “[This type of robot] could leap into the bottom of a crater, take samples and return to a wheeled rover,” points out Hawkes. His team is already working with NASA. They hope to turn their robot into a space explorer.

SAN FRANCISCO: Indian-Origin Founder Unveils Wearable Device That Records Every Moment Of Your Life
SAN FRANCISCO: Advait Paliwal, an Indian-origin entrepreneur, has recently introduced a wearable AI device called Iris, designed to provide users with “infinite memory.” According to Paliwal, the device captures “pictures every minute,” which are stored either on the device or in the cloud, allowing users to preserve life’s small moments and recognize patterns often overlooked.
In a series of tweets, Mr Paliwal, who is based in San Francisco, explained that Iris not only organises the photos into a timeline but also uses AI to generate captions and help users recall forgotten details. Additionally, the device features a “focus mode,” which detects when the wearer is distracted and offers reminders to refocus.
Mr. Paliwal shared that the design of Iris is inspired by the evil eye symbol. He developed the device over the summer at the Augmentation Lab in Cambridge, part of a two-month AI and hardware talent accelerator program. After the program, Mr Paliwal presented Iris to over 250 attendees at the MIT Media Lab, where he received positive feedback, with many expressing interest in owning the device.
Highlighting its potential, Mr Paliwal suggested that Iris could offer safety and health benefits, such as aiding doctors in understanding patients’ daily habits or ensuring workplace safety compliance. In elderly care, the device could help caregivers monitor patients without being intrusive.
However, after Mr Paliwal shared his post on X (formerly Twitter), reactions were mixed. While some users expressed excitement, others raised privacy concerns. One person commented, “It’s an interesting concept, but I wouldn’t want to interact with someone wearing this, taking a photo every minute.” Paliwal responded by pointing out that people are already “constantly taking mental photos.”
Others were more enthusiastic, with one user noting, “I’ve been searching for a device like this for years! A picture every minute should be enough if it archives, organizes, labels, and retrieves them.” Another user praised the concept, saying, “Love the idea. The design and name are perfect. Great work!”

TEXAS: Meet Gopi Thotakura, Indian Who Will Soon Go To The Edge Of Outer Space
TEXAS: In an unprecedented leap towards the stars, pilot Gopichand Thotakura is set to become the first Indian to venture into space as a tourist. Selected as part of the elite crew for Blue Origin’s New Shephard-25 (NS-25) mission, Mr Thotakura will make a journey beyond the Earth’s atmosphere along with five other candidates.
Gopichand Thotakura, an entrepreneur and pilot, joins a distinguished lineup of 31 candidates who have flown beyond the Karman line, the boundary between Earth’s atmosphere and outer space.
A connoisseur of the skies since his youth, Mr Thotakura’s passion for flight saw him defy conventional norms, learning to pilot aircraft before mastering the art of driving. To further his passion, he graduated from Embry-Riddle Aeronautical University with a Bachelor of Science in Aeronautical Science.
Describing him, Blue Origins wrote, “Gopi is a pilot and aviator who learned how to fly before he could drive. Gopi pilots bush, aerobatic, and seaplanes, as well as gliders and hot air balloons, and has served as an international medical jet pilot. A lifelong traveler, his most recent adventure took him to the summit of Mt. Kilimanjaro.”
Born in Vijayawada, the 30-year-old currently runs Preserve Life Corp, a global center for holistic wellness and applied health located near Hartsfield-Jackson Atlanta International Airport
Each member of the NS-25 mission will carry a postcard on behalf of Blue Origin’s foundation, Club for the Future, symbolizing the collective dreams and aspirations of young minds worldwide.
From an environmental standpoint, the NS-25 mission heralds a new era of sustainability in space exploration.
“Nearly 99% of New Shepard’s dry mass is reused, including the booster, capsule, engine, landing gear, and parachutes. New Shepard’s engine is fueled by highly efficient liquid oxygen and hydrogen. During flight, the only byproduct is water vapor with no carbon emissions,” Blue Origins said in their statement.
The launch date for the mission is yet to be announced.
The mission also includes former Air Force Captain Ed Dwight, who was selected by US President John F Kennedy in 1961 as the country’s first Black astronaut candidate but was never granted the opportunity to fly to space.
Blue Origin has carried out six crewed flights — some passengers were paying customers and others were guests — since July 2021, when CEO Jeff Bezos himself took part in the first.
The company is also developing a heavy rocket for commercial purposes called New Glenn, with the maiden flight planned for next year.
This rocket, which measures 98 meters (320 feet) high, is designed to carry payloads of as much as 45 metric tons into low Earth orbit.
