For decades, event cameras, which emulate the biological retina by continuously monitoring changes in light intensity, have promised to revolutionize how robots perceive the world by allowing them to react faster and operate more reliably than conventional cameras permit.For decades, event cameras, which emulate the biological retina by continuously monitoring changes in light intensity, have promised to revolutionize how robots perceive the world by allowing them to react faster and operate more reliably than conventional cameras permit.[#item_full_content]

Animals have long been one of the primary sources of inspiration for robotics researchers. This is because they rely on sophisticated biological mechanisms and locomotion strategies that could be artificially reproduced in robots to equip them with desired capabilities.Animals have long been one of the primary sources of inspiration for robotics researchers.

A team of University of Toronto Engineering researchers has developed a flexible foot pad for the “Hopcopter”—a one-legged, hopping robot they developed—significantly enhancing its performance on sand, ice and other difficult terrain.A team of University of Toronto Engineering researchers has developed a flexible foot pad for the “Hopcopter”—a one-legged, hopping robot they developed—significantly enhancing its performance on sand, ice and other difficult terrain.[#item_full_content]

Flying insects, such as fruit flies, bees, dragonflies and mosquitoes, can dart through narrow spaces and survive collisions with various objects. In contrast, many flying robots fall, suffer damage or even break down when they hit nearby surfaces or objects.Flying insects, such as fruit flies, bees, dragonflies and mosquitoes, can dart through narrow spaces and survive collisions with various objects.

Researchers have covered robotic fingers with a new artificial skin that allows the hand to grasp fragile pencil lead and pull away from a needle before it punctures the covering. Both actions depend on more than sensitive sensors. The robot must also receive and interpret their signals quickly enough to respond.Researchers have covered robotic fingers with a new artificial skin that allows the hand to grasp fragile pencil lead and pull away from a needle before it punctures the covering.

Humanoid robots, robotic systems with a body shape that resembles that of humans, could tackle various chores and everyday manual tasks. To successfully complete these tasks, however, the robots should be able to reliably coordinate their movements, posture and how they touch or grasp different objects.Humanoid robots, robotic systems with a body shape that resembles that of humans, could tackle various chores and everyday manual tasks.

Lab-grown skeletal muscle tissue can contract, but the movement is often so slight that it is barely visible. This poses a problem for biohybrid robots designed to move using living muscles. Researchers at ETH Zurich have now demonstrated that it is not just the amount of muscle tissue that matters, but above all how the muscle and the artificial scaffold interact.Lab-grown skeletal muscle tissue can contract, but the movement is often so slight that it is barely visible.

It’s important for a robot not just to learn a task optimally, but to complete it without going off the rails of reasonable expectations. Until now, roboticists could have one or the other. Aerospace engineering researchers in The Grainger College of Engineering, University of Illinois Urbana-Champaign, combined reinforcement learning with control theory to guarantee robot stability and improve tracking performance by up to 15% compared with existing methods.It’s important for a robot not just to learn a task optimally, but to complete it without going off the rails of reasonable expectations.

Large language models (LLMs) like OpenAI’s ChatGPT, Anthropic’s Claude and Google Gemini are increasingly being used to help robots perform tasks, but what if LLMs could be exploited to turn helpful robots into harmful robots?Large language models (LLMs) like OpenAI’s ChatGPT, Anthropic’s Claude and Google Gemini are increasingly being used to help robots perform tasks, but what if LLMs could be exploited to turn helpful robots into harmful robots?[#item_full_content]
