Over the past few years, we have seen major advancements in robotics. However, their movements still mostly rely on rigid motors at each joint. This is a big part of why robots always appear to move so stiffly. However, researchers at the EPFL research institute in Switzerland have come up with a motor that could provide much smoother movements for robots. The motor is being called the FiberMotor, and in a new study in Advanced Materials, the team says it could eventually be used in soft exosuits and other wearable assistive devices to provide less jerky movements all around. The…
