Locomotion, the ability to move from one place to another, is an essential survival strategy for virtually every organism. Adapting to the unpredictable terrain they run into, cells, fungi and microorganisms autonomously move and change shape to explore their environments, while animals run, crawl, slither, roll and jump.Locomotion, the ability to move from one place to another, is an essential survival strategy for virtually every organism.

Empa researchers are working on producing artificial muscles that can keep up with the real thing. They have now developed a method of producing the soft and elastic yet powerful structures using 3D printing.Empa researchers are working on producing artificial muscles that can keep up with the real thing.

Engineers have designed a tiny, low-weight and cordless robot that can act independently and with ultra-high precision in all directions in some of the most extreme conditions. The robot, which the designers call “Holonomic Beetle 3” (or HB-3)—as they were inspired by the movements and anatomy of the rhinoceros beetle—combines the use of piezoelectric actuators with autonomous technology to enable micro-scale manipulation tasks that were previously out of reach for robots.Engineers have designed a tiny, low-weight and cordless robot that can act independently and with ultra-high precision in all directions in some of the most extreme conditions.

It is estimated that about 80 million people worldwide live with a tremor. For example, those who live with Parkinson’s disease. The involuntary periodic movements sometimes strongly affect how patients are able to perform daily activities, such as drinking from a glass or writing.It is estimated that about 80 million people worldwide live with a tremor.

Johns Hopkins University engineers have developed a pioneering prosthetic hand that can grip plush toys, water bottles, and other everyday objects like a human, carefully conforming and adjusting its grasp to avoid damaging or mishandling whatever it holds.Johns Hopkins University engineers have developed a pioneering prosthetic hand that can grip plush toys, water bottles, and other everyday objects like a human, carefully conforming and adjusting its grasp to avoid damaging or mishandling whatever it holds.[#item_full_content]

Aibo, the cute-looking robot puppy developed by Sony, was designed to be a household companion. The robot can already emulate many of the movements and behaviors of real dogs, such as walking on four legs, responding when it is called by its name, reacting to toys, performing tricks and responding to cuddles.Aibo, the cute-looking robot puppy developed by Sony, was designed to be a household companion.

Over the past few years, engineers have developed increasingly advanced robotic systems already introduced in some public spaces and could soon be deployed in home environments. Many of these robots are humanoids, meaning that their body structure and physical features resemble those of humans.Over the past few years, engineers have developed increasingly advanced robotic systems already introduced in some public spaces and could soon be deployed in home environments.

From mountain goats that run up near-vertical rock faces to armadillos that roll into a protective ball, animals have evolved to adapt effortlessly to changes in their environment. In contrast, when an autonomous robot is programmed to reach a goal, each variation in its pre-determined path presents a significant physical and computational challenge.From mountain goats that run up near-vertical rock faces to armadillos that roll into a protective ball, animals have evolved to adapt effortlessly to changes in their environment.

Springtails, small bugs often found crawling through leaf litter and garden soil, are expert jumpers. Inspired by these hopping hexapods, roboticists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have made a walking, jumping robot that pushes the boundaries of what small robots can do.Springtails, small bugs often found crawling through leaf litter and garden soil, are expert jumpers.

A recent breakthrough in photothermal actuator design has been achieved by a research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, led by Prof. Tian Xingyou and Prof. Zhang Xian. The team developed a novel superstructure liquid metal/low expansion polyimide/polydimethylsiloxane (LM@PI/PDMS) actuator, which combines rapid movement with impressive load-carrying capacity—an achievement that has eluded previous actuator designs.A recent breakthrough in photothermal actuator design has been achieved by a research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, led by Prof. Tian Xingyou and Prof. Zhang Xian.
