Touch and force sensing
A 640 × 480 camera images a 19 × 16 mm gel, giving contact shape and shear at pixel resolution instead of a single force value.

GelSight DIGIT Tactile Sensor
GelSight DIGIT (DG-01) is a vision-based fingertip tactile sensor for robot hands: an OVM7692 colour camera images a 19 × 16 mm elastomer lit by three RGB LEDs and streams it over USB (VGA 640 × 480, 30 fps by default; 60 fps in the paper table). The housing is 20 × 27 × 18 mm and about 20 g with a press-fit replaceable gel.

Grasping and manipulation
20 × 27 × 18 mm and about 20 g: small enough to mount on multi-finger robot hands for in-hand manipulation.
Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.

Specifications
Motor performance
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Thermal limits by level
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
