From a 🍷 to an 🥚 and even a 🌱 this fabric-based soft robotic gripper can handle an extraordinarily wide range of irregular shapes. Joel Marthelot CNRS 🌍 Read the article: ow.ly/uxxc50O4Npe

We use the closing mechanism to build a gripper based on several V-actuators connected in a closed loop. We predict the mechanical response of the star, optimize the geometry and maximize the contraction and stiffness.

We increase the efficiency of the gripper by stacking several stars and increasing the friction with the object by covering the corners with an elastomer. The clamp can lift heavy and irregularly shaped objects thanks to the high bending stiffness of the inflated tubes.

Inextensible balloons are a versatile solution for soft robotics! Joel Marthelot CNRS 🌍
