Robotiq 2F-85
The industry-standard two-finger adaptive gripper. Fingers conform to the object, 85 mm stroke, and it has been integrated into more research arms than anything else.
The role it plays
The end effector is what the task actually touches and it usually deserves more thought than the arm. Grasping divides into force closure (fingers), form closure (soft, compliant) and adhesion (vacuum, magnetic). Soft hands for variety, parallel jaws for speed, vacuum for flat non-porous parts.
Typical use: Pick and place, bin picking, research manipulation.
What the numbers actually mean
The headline figure is 85 mm (0 – 85 mm opening) (stroke), with 20 – 235 N adjustable as the next most load-bearing number (grip force). At $5.8k in the end effectors tier it sits as a capital purchase. At this price you are buying documentation, repeatability and support as much as metal, and the integration cost is usually larger than the part.
How it compares
Same subsystem, closest alternatives. The primary spec column is usually the one that decides it.
