A thumb-shaped sensor with a camera inside, developed by researchers at Germany's Max Planck Institute for Intelligent Systems (MPI-IS), uses computer vision and a deep neural network to infer haptic contact information.
The Insight system generates a three-dimensional force map when the thumb is touched, estimating where objects come into contact with the sensor and the amount of force applied.
Said MPI-IS's Huanbo Sun, "Our unique hybrid structure of a soft shell enclosing a stiff skeleton ensures high sensitivity and robustness. Our camera can detect even the slightest deformations of the surface from one single image."
