Reconfigurable Soft Grippers

Our soft grippers have adjustable gripping space and pose, making them an all-in-one gripping solution to handle a diverse range of products of various shapes and sizes. Just one gripper will be enough to grip different types of products.

Currently, we have developed 2 types of reconfigurable grippers – GourmetGrip for food-safe manipulation, and UnisoGrip for Fast-moving Consumer Goods (FMCG) picking. Demo videos can be found under the ‘Resources’ Section.

Fabricated with 3D printing technologies, our grippers and finger designs can be further customized and optimized for specific gripping requirements.

Our GourmetGrip can be used to handle most of the food items in e.g. central kitchens, food assembling lines and agriculture farms. It has been tested to grip at least 50 different types of food items with various shapes and sizes safely and stably, such as uncooked tofu, pudding, cake, strawberry, broccoli, sausage, raw egg, and assorted vegetables, with a success rate of 93%.

Our UnisoGrip can be used for picking and sorting FMCG products, especially in the e-commerce sector where every online order consists of different types of products. The gripper has been tested to pick at least 30 different types of products with various shapes, sizes and types of packaging successfully, such as pouched products (e.g. a bag of coffee powder), tubed products (e.g. toothpaste), boxed products (e.g. a box of cereal), and bottled products (e.g. a bottle of shampoo). It can also handle products of different sizes, from as small as a piece of chocolate ball, to as big as a box of 500 g cereal.

The customized gripping solutions can also be in various sectors such as pill picking and packing packaged foods into boxes or plastic bags for export, etc.

Benchmarking tests have been conducted to compare the grippers with other commercially available grippers. The results showed that our grippers can provide a 22% increase in gripping efficiency. Moreover, compared to using multiple grippers and tool changers to handle different products, the one-fits-all grippers can help users to save the operating cost by up to 36%. Reconfigurable grippers also provide 100% gripping adaptability with its universal gripping function, which is a feature absent in most of commercially available grippers.
