The Design

About Bloom Préhenseur robotique souple

Bloom est un préhenseur robotique souple conçu pour les tâches automatisées de manipulation et d'assemblage. Le préhenseur s'inspire de la main humaine ainsi que de la floraison cyclique de la rose de France. Réalisé en silicone, Bloom est actionné par pression d'air. Des ongles rétractables permettent la préhension précise d'objets fins. Des pétales pliables permettent de puiser des matériaux granulaires. Une paume flexible modifie la largeur d'ouverture pour les objets volumineux. De faibles pressions, sans danger, suffisent à passer d'un mode de préhension à l'autre. Bloom peut manipuler des objets délicats en toute sécurité à proximité des opérateurs humains.

Unique Properties: Bloom is a bio-inspired, pneumatically actuated, shape morphing soft robotic gripper that is capable of on-site rapid workspace reconfigurability. It features passive retractable nails, bi-directional foldable petals, and a flexible palm to adapt to various grasping and manipulation tasks. The ability to rapidly reconfigure grasping workspace on-the-fly allows Bloom to perform assembly tasks consisting of highly varying subtasks, a feat previously not possible using conventional rigid or existing soft grippers.
Dimensions & Packaging: 115 x 115 x 152mm
Tags: Soft Robotics, Soft Robots, Bio-Inspired Design, Biomimicry, Robotics, Material Science
Production Technology: Design Optimization using FEA, 3D Printing, Silicone Moulding & Casting
Design Challenge: Consumer goods, logistics, and food industries have been benefiting from robotic intervention to meet evolving demands. In such industries, reliable robotic handling of food rely on versatile gripper interfaces with comprehensive and adaptive capabilities. Compared to traditional rigid grippers, Bloom, a state-of-the-art soft gripper utilizes compliant soft actuators made using functional hyperelastic materials, allowing it to grasp a wider range of geometries safely and reliably.
Research: Silicone and air are both soft materials and are the main components in this soft gripper. Because of this, Bloom is able to interface with soft objects safely and effectively.

Bloom can be used in many circumstances including food preparation and healthcare. Because of its material compliance, it is able to work closely with delicate objects and human coworkers. Thus, narrowing the gap between robots and humans.
Inspiration: A product of the Bio-Inspired Robotics Design (BRD) Lab at the Singapore University of Technology and Design (SUTD), Bloom was inspired by both the dexterity of the human hand and the intentional cyclic blooming of the Rosa gallica (Gallic Rose). Mimicking the function of the corpus unguis, (human fingernail) Bloom, can grasp objects as thin as 300 microns, large objects as heavy as 1.4kgs, while being able to scoop objects as small as 1.5 millimeters in radius.
Project Duration: The project concluded in February 2021, at the Singapore University of Technology and Design (SUTD)
Operation Flow: Bloom features retractable nails to help in precision grasping of small and thin objects. An optimized bi-directional flap design allows for scooping actions for granular objects such as grains, jelly or scrambled eggs. A multi-material palm design allows for changing Bloom’s aperture for wide objects. Bloom utilizes low, safe pressures (-80kPa to 60kPa) to switch between and operate the various grasping modes.
