"RobOstrich" Manipulator: A Novel Mechanical Design and Control Based on the Anatomy and Behavior of an Ostrich Neck

RA-L 2023

Flexible manipulators have high degrees of freedom and deformability, enabling dexterous movements and allowing for unexpected contacts with the environment. Underactuated tendon-drive mechanisms are the most widely adopted because of their simplicity and effectiveness. However, they suffer from dif

Wireless Powered Dielectric Elastomer Actuator

RA-L 2021

The need for cable connection with soft robotic systems suppresses the benefits granted by their softness and flexibility. Such systems can be untethered by equipping batteries or by relying on non-electrical actuation mechanisms. However, these approaches cannot simultaneously support long-term and

Soft Tactile Fingertip to Estimate Orientation and the Contact State of Thin Rectangular Objects

RA-L 2020

A soft tactile fingertip was developed to provide the contact feedback on characteristics of an object for performing automatic assembly of electronic parts, such as a thin circuit board. However, designing a tactile fingertip with simple design and minimal number of sensors that can estimate orient

Position-force combination control with passive flexibility for versatile in-hand manipulation based on posture interpolation

IROS 2016poster

In-hand manipulation is often needed to accomplish a practical task after grasping an object. In-hand manipulation of variously sized and shaped objects in multi-fingered hands without dropping the object is challenging. In this paper we suggest a combined strategy of force control and passive adapt…
