Flexiv Grav Enhanced Gripper Review: Specs, Price and Applications
The Flexiv Grav Enhanced is a hybrid gripper that combines force-controlled two-finger pinching with gecko-inspired superfriction gripping. One tool handles small precise parts and large or irregular items, removing tool changes in mixed-SKU work.
It offers 52 mm stroke per jaw, a gripping force range of 1 N to 30/80 N, 0.1 mm finger position repeatability and IP67 protection. It can handle almost any item under 5 kg (11 lb) that fits within its grasp, and in gecko mode lifts up to 5 kg.
Quick Verdict
An inventive gripper for unpredictable product mixes. Gecko superfriction plus force-controlled fingers covers far more items than either method alone.

Design and Operating Principle
Gecko-inspired adhesives use microstructures that create strong friction and van der Waals adhesion on smooth surfaces. The Grav's gecko grip is passive, needing no external energy or vacuum pump, which saves air and noise compared with suction.
For small or precise items, the fingers switch to force-controlled parallel pinching, with integrated force sensing that allows delicate handling from as low as 1 N.
An optional cleaning station maintains the gecko surface, because dust reduces adhesion over time. IP67 protection makes the gripper suitable for demanding environments and mobile platforms.
Integration and Selection
Test the actual SKU mix to determine which items use gecko mode and which use pinching. Plan cleaning cycles for the gecko pads.
Use the plug-and-play integration on Flexiv robots, or the universal interface for other arms.
