The GR-Dexter System, recently launched by the Seed Team of ByteDance, has achieved a "holy grail-level" breakthrough in the robotics field. As the world’s first integrated framework to scale VLA models to high-degree-of-freedom dexterous hands, it has successfully overcome three major challenges: the curse of dimensionality, perceptual blind spots, and data scarcity. The key to the dexterous hand’s precise sensing capability lies in FiSensor High-Density Tactile Electronic Skin.
