Multifunctional Magnetic Muscles for Soft Robotics

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Sept. 10, 2024

Despite recent advancements, artificial muscles have not yet been able to strike the right balance between exceptional mechanical properties and dexterous actuation abilities that are found in biological systems. Here, we present an magnetic muscle exhibits multiple remarkable demonstrates comprehensive actuating performance, surpassing those of muscles. This utilizes a composite configuration, integrating phase-change polymer ferromagnetic particles, enabling active control over complex motions through remote laser heating field manipulation. Consequently, can dynamically adjust its stiffness as needed, achieving switching ratio exceeding 2.7 × 10³. adaptability facilitates substantial load-bearing capacity, with specific load capacities up 1000 3690 for tensile compressive stresses, respectively. Moreover, it reversible extension, contraction, bending, twisting, stretchability 800%. We leverage these distinctive attributes showcase versatility this soft continuum robotic manipulator. It adeptly executes various programmable responses performs tasks while minimizing vibrations. Furthermore, demonstrate excels across aspects compared existing actuators.

Survey of learning-based approaches for robotic in-hand manipulation

Frontiers in Robotics and AI, Journal Year: 2024, Volume and Issue: 11

Published: Nov. 5, 2024

Human dexterity is an invaluable capability for precise manipulation of objects in complex tasks. The robots to similarly grasp and perform in-hand critical their use the ever changing human environment, ability replace manpower. In recent decades, significant effort has been put order enable capabilities robotic systems. Initial manipulators followed carefully programmed paths, while later attempts provided a solution based on analytical modeling motion contact. However, these have failed provide practical solutions due inability cope with environments uncertainties. Therefore, shifted learning-based approaches where data collected from real world or through simulation, during repeated complete various vast majority learning focused data-based models that describe system some extent Reinforcement Learning (RL). RL, particular, seen growing interest remarkable generate problems minimal guidance. this survey paper, we track developments manipulations and, explore challenges opportunities. This designed both as introduction novices field glossary terms well guide novel advances advanced practitioners.

Towards higher load capacity: innovative design of a robotic hand with soft jointed structure

Bioinspiration & Biomimetics, Journal Year: 2024, Volume and Issue: 19(5), P. 056022 - 056022

Published: Aug. 29, 2024

Abstract In this paper, the innovative design of a robotic hand with soft jointed structure is carried out and tendon-driven mechanism, master-slave motor coordinated drive thumb coupling transmission mechanism steering are proposed. These designs allow for more effective actuation in each finger, enhancing load capacity while maintaining key performance indicators such as dexterity adaptability. A mechanical model finger was made to determine application limitations capacity. The then prototyped set experiments. experimental results showed that proposed theoretical were reliable. Also, fingertip force could reach up 10.3 N, 72.8 N. When grasping target objects different sizes shapes, able perform various power precision Cutkosky taxonomy. Moreover, had good flexibility adaptability by means adjusting envelope state autonomously.
