Flexible Mechanical Metamaterials Enabled Electronic Skin for Real‐Time Detection of Unstable Grasping in Robotic Manipulation (Adv. Funct. Mater. 23/2022)

Metamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).

By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.

Vision Techniques for Robotic Manipulation and Grasping

In this paper we present a few different vision techniques used for robotic manipulation and grasping tasks. These tasks are performed in a domestic environment and consider manipulation of everyday objects such as a package of cereals, cups, soda cans, etc. The variety and dynamics of real world settings introduce a number of problems such a varying lighting conditions, complicated textural pr...

Robotic Manipulation for Identification of Flexible Objects

This paper provides preliminary insight into stiffness profile identification of a complex flexible object by robotic manipulation. The object is in the shape of the letter ‘Y’, chosen to resemble a living plant. The object is approximately modelled as a spring mass system. The robot manipulates the object with one or two arms, grasped at the ends of the ‘Y’, and makes visual measurements which...

A Passivity-Based Control Scheme for Robotic Grasping and Manipulation

This article presents and discusses the application of an impedance control strategy to robotic grasping tasks. This control strategy, that can be used for both tips and full grasps, is based on two fundamental aspects. The first is the so-called ‘virtual object’ concept, by means of which the modalities of interaction between the fingers and the real objects can be properly defined. The second...
