Tiny, knotted robots jump, fly and plant seeds

When a knot lets go, it doesn’t just fall apart. It snaps. That simple observation led Penn Engineers to rethink what a knot can do. Instead of treating it as something that holds tension, they asked a different question: what happens when you design a knot to release it? The answer is a tiny, soft robot capable of leaping meters into the air, flipping mid-flight, spinning like a propeller or even gliding back to where it started.When a knot lets go, it doesn’t just fall apart.

A paddle-wielding robot is so adept at playing table tennis that it is posing a tough challenge to elite human players and sometimes defeating them, according to a new study that shows how advances in artificial intelligence are making robots more agile.A paddle-wielding robot is so adept at playing table tennis that it is posing a tough challenge to elite human players and sometimes defeating them, according to a new study that shows how advances in artificial intelligence are making robots more agile.[#item_full_content]

When assessing the ripeness of fruit, sight and smell can tell you a lot, but the best indicator is often how the fruit feels. Cornell researchers used stretchable fiber-optic sensors to create a soft robot gripper that can predict the ripeness of strawberries by touch, then gently twist them off their branch or vine without causing any damage.When assessing the ripeness of fruit, sight and smell can tell you a lot, but the best indicator is often how the fruit feels.

A humanoid robot sprints to victory in Beijing, beating the human half-marathon world record

A humanoid robot that won a half-marathon race for robots in Beijing on Sunday ran faster than the human world record in a show of China’s technological leaps.A humanoid robot that won a half-marathon race for robots in Beijing on Sunday ran faster than the human world record in a show of China’s technological leaps.[#item_full_content]

Breaking away from conventional robots that perform only predefined functions once fabricated, researchers have developed a next-generation artificial muscle that can change its shape in real time, recover from damage, and even be reused. The study is published in Science Advances.Breaking away from conventional robots that perform only predefined functions once fabricated, researchers have developed a next-generation artificial muscle that can change its shape in real time, recover from damage, and even be reused.

When it comes to teamwork, we could all learn something from ants. These relatively simple, small-brained animals are famous for their ability to collectively build massive, intricate, climate-controlled structures, despite having neither a blueprint nor a worksite foreman.When it comes to teamwork, we could all learn something from ants.

In today’s manufacturing environments, upgrading a robot fleet often means starting from scratch—not only replacing hardware, but also reprogramming tasks. Even when two robots are built to perform similar jobs, different joint arrangements or movement limits mean that a task programmed for one robot often can’t be used on another. Enabling skills to transfer directly between robots could make these systems more sustainable and cost-efficient.In today’s manufacturing environments, upgrading a robot fleet often means starting from scratch—not only replacing hardware, but also reprogramming tasks.

Snake-like robots represent the future of rescue. Their slender bodies allow them to navigate narrow spaces, uneven terrain, and water surfaces, entering places that would be hazardous for humans. This could potentially save lives in earthquake-prone areas, like Japan.Snake-like robots represent the future of rescue.

A KAIST research team has developed quadrupedal robot technology that not only enables walking by estimating terrain without visual information, but also allows the robot to perceive its surroundings through cameras and LiDAR sensors and make its own decisions while walking, much like animals that visually examine terrain and adjust their steps. This technology is also expected to be extended to various robotic platforms such as wheeled-legged robots and humanoid robots.A KAIST research team has developed quadrupedal robot technology that not only enables walking by estimating terrain without visual information, but also allows the robot to perceive its surroundings through cameras and LiDAR sensors and make its own decisions while walking, much like animals that visually examine terrain and adjust their steps.

Muscles are remarkably effective systems for generating controlled force, and engineers developing hardware for robots or prosthetics have long struggled to create analogs that can approach their unique combination of strength, rapid response, scalability, and control. But now, researchers at the MIT Media Lab and Politecnico di Bari in Italy have developed artificial muscle fibers that come closer to matching many of these qualities.Muscles are remarkably effective systems for generating controlled force, and engineers developing hardware for robots or prosthetics have long struggled to create analogs that can approach their unique combination of strength, rapid response, scalability, and control.
