Robots can now 'see' touch thanks to a new color-changing tactile sensor
Researchers at Queen Mary University of London have developed a new tactile sensor that changes color under pressure, allowing robots to 'see' touch using standard cameras. This innovation simplifies robotic hardware by removing the need for complex electronic sensor arrays.
Most robots are pretty good at seeing, but touching? That's been a much tougher problem. While humans instinctively know how hard they're gripping a coffee mug or pressing a button, robots have traditionally relied on complex arrays of tiny sensors to estimate the same thing. Now, researchers at Queen Mary University of London believe they've found a much simpler solution: make touch visible.
