Applications

The SQUARE 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 like Robo Sync for 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.
