piSoftGrip: Precision Vacuum‑Based Silicone Gripper for Delicate, Odd‑Shaped Parts

Piab’s new piSoftGrip is a vacuum‑powered soft gripper designed for handling sensitive, lightweight items with irregular shapes—think toys, small components, or uniquely textured surfaces. Crafted from food‑grade silicone, the gripper delivers a gentle yet reliable grasp, making it ideal for industries that demand both precision and safety.

Featuring a single‑piece construction, the device combines three compliant gripping fingers with a vacuum chamber, all integrated into one seamless unit. Gripping force is precisely controlled by adjusting the vacuum level, ensuring a firm hold without damaging the item.

The first iteration of piSoftGrip can comfortably manage objects up to 50 mm (1.97 in.) in diameter. Larger models are in development to broaden the range of applications.

Standard fittings are compatible with Piab’s existing piGrip suction cups, and an optional stainless‑steel fitting provides wash‑down capability for demanding environments.

When paired with Piab’s piCobot end‑of‑arm vacuum tool, the piSoftGrip offers a true plug‑and‑play solution for collaborative robots. Both tools utilize compressed‑air‑saving technology, meaning virtually no energy is required to engage or release a grip—boosting efficiency and reducing operational costs.

With its blend of softness, adaptability, and low‑energy operation, piSoftGrip sets a new standard for handling delicate, oddly shaped parts in modern automation.
