Researchers have developed a snake-like robot, FiloBot, that can 3D print its own body to grow longer, mimicking skototropisms. The robot's head spins and uses 3D printing to create more body mass, allowing it to elongate and be programmed to grow in desired ways. FiloBot has potential uses in monitoring natural environments, building autonomous structures, and testing pollution levels in hard-to-reach areas.

A soft robotic garment designed by researchers from Harvard SEAS and Boston University Sargent College has shown promise in eliminating freezing of gait in Parkinson's patients. The device, which is worn around the hips and thighs, assists with leg swings, enabling longer strides and improved mobility. In a study with a 73-year-old Parkinson's patient, the robotic garment completely removed freezing episodes during indoor walks, potentially offering a new way to enhance independence for those affected by this symptom of Parkinson's disease. The research, which will appear in Nature Medicine, underscores the potential of soft robotics in medical applications and neurorehabilitation.

Researchers have developed a soft robotic tentacle inspired by octopuses, capable of grasping small objects in air or water. The tentacle mimics the bend propagation movement of an octopus arm and can be operated remotely using a glove that fits over one finger. The robotic tentacle consists of five segments made of soft silicone embedded with metal wires, forming an electronic network that mimics the nervous system of an octopus arm. The tentacle can expand 1.5 times its original length and incorporates sensory feedback, allowing the operator to feel the engagement of the suckers at the tip. The technology has potential applications in marine research, biomedical technology, and artificial organs.

Researchers have recreated a 450-million-year-old extinct marine organism, known as a pleurocystid, as a soft robotic replica. The robot, made from a combination of 3D-printed elements and polymers, mimics the flexible nature of the creature's tail-like muscular stem. By studying the robot's movements, researchers hope to gain insights into how extinct organisms moved and how this contributed to the evolution of animals. This breakthrough in paleobionics opens up possibilities for replicating more extinct creatures and understanding the biomechanical factors that drove evolution.

Scientists have created a soft robot replica of the ancient echinoderm pleurocystitid to study its efficient movement across the ocean floor over 450 million years ago. By analyzing the creature's fossils, researchers discovered that its sweeping tail motion allowed it to move with power and efficiency. This development in paleobionics, the field of robotics inspired by extinct species, could lead to practical applications in modern robotics and exploration of hard-to-navigate environments like the deep-sea floor. The pleurocystitid robot could push the fields of soft robotics, biology, and paleontology to the next level with its research.

Researchers have created a soft robotic replica of pleurocystitids, a marine organism that lived 450 million years ago, using fossil evidence. This new field of study, called paleobionics, aims to understand the biomechanical factors that drove evolution by using soft robotics. The team used computational simulations and 3D printed elements to mimic the flexible structure of the organism's appendage. They discovered that pleurocystitids likely moved by sweeping motions and that increasing the length of their stem increased their speed without requiring more energy. This breakthrough opens up possibilities for studying extinct organisms and learning more about the history of life on Earth.
