This article presents a two-finger soft-robotic gripper with enveloping grasping (EG) and
pinching grasping (PG) modes. The proposed soft-robotic gripper is based on a two-finger …

This article presents an innovative, motor-driven, three-finger compliant gripper for adaptive
grasping of size-varied delicate objects. An optimized compliant finger design is identified …

Various robotic grippers have been developed over the past several decades for robotic
manipulators. Especially, the soft grippers based on the soft pneumatic actuator (SPA) have …

Compared with traditional rigid grippers, soft grippers are made of lightweight and soft
materials and have the characteristics of flexible contact and strong adaptability, which are …

This article presented a four-fingered soft bionic robotic gripper with variable effective
actuator lengths. By combining approaches of finite element analysis, quasi-static analytical …

In this study, we built a four-fingered soft robotic gripper with tunable effective finger lengths.
This robotic model is purely made of soft materials and allows two working modes that …

Soft grippers have attracted increasing attention due to safer and more adaptable human–
machine and environment-machine interactions. However, it has always been a challenge …

In soft robotics, there is still a great need for a universal but simple gripper that realizes a
high level of adaptability as well as a gentle touch to a wide variety of unknown objects of …

This paper presents a novel structure-controlled variable stiffness robotic gripper that
enables adaptive gripping of soft and rigid objects with a wide range of compliance. With the …

A novel soft-robotic gripper design is presented, with three soft bending fingers and one
passively adaptive palm. Each soft finger comprises two ellipse-profiled pneumatic …
