Digit 360

Meta’s humanoid fingertip-shaped multimodal tactile sensor, sensing force, vibration, temperature, and more.

Digit 360 is a humanoid fingertip tactile sensor Meta FAIR released in late October 2024, manufactured and sold by the company GelSight. It continues the operating principle of DIGIT-style vision-based tactile sensors — an internal camera photographing the deformation of a soft gel surface — but shaped as a hemispherical fingertip that can sense contact from any direction. The paper reports about 8.3 million taxels (tactile pixels), able to distinguish surface detail down to 7 micrometers, with normal- and shear-force resolution around 1 mN, sensing vibration up to 10 kHz, and also sensing temperature and even smell; the fingertip has a built-in AI accelerator chip that can do fast, reflex-like local processing. Meta simultaneously released the Sparsh tactile encoder and the Digit Plexus platform, which connects multiple types of tactile sensors to the same hand.

ExampleMeta’s Digit Plexus platform can mount Digit 360, DIGIT, ReSkin, and other tactile sensors on the same robotic hand, sending all their data back over a single cable, making it convenient to collect tactile data for dexterous manipulation.
