Applications

TheSQUARE Hand (SQH Series)is designed for flexible automation environments where object shapes, sizes, and materials vary. Its adaptive belt-type gripping and force control make it ideal for:

Logistics & warehousing– picking assorted bottles, pouches, and cartons from bins or shelves
Packaging lines– gentle handling of cosmetic, pharmaceutical, and food containers
Assembly processes– handling lightweight and irregular components safely
E-commerce fulfillment– mixed-item picking and packing
Medical and laboratory automation– gripping delicate plastic bottles, test containers, and reagent packages
General manufacturing– transferring small or soft objects without deformation

Key Features

Force-Sensing Control– Equipped with built-in sensors to detect contact pressure and automatically adjust gripping force for each object type.
Belt-Type Soft-Gripping System – Uses a flexible, belt-driven wrapping motion to hold irregular or soft surfaces without slippage or damage securely.
Adaptive Object Recognition– Automatically compensates for variations in size, shape, and texture.
Broad Compatibility– Easily integrates with major collaborative robot brands, including Universal Robots, FANUC, Yaskawa, and Kawasaki.
Multi-Object Handling– Suitable for bottles, pouches, boxes, tubes, and even loosely packed items.
Compact & Lightweight Design– Ideal for small workspace automation or cobot installations.
Plug-and-Play Integration– Compatible with robot control platforms likeRobo Syncfor simplified setup and control.
High Safety & Reliability– Compliant with cobot safety standards; designed to prevent product or operator injury.
Flexible Orientation Control– Can grip and reorient objects without release, reducing cycle time.
Low-Maintenance Structure – Belt and actuator design minimize wear and simplify servicing.
