1 Introduction
Most robots are discrete mechanisms constructed from a series of rigid links. These are connected by discrete single degree of freedom joints, and controlled movement is only generated at these joints. The intermediate links may be considered infinitely stiff and essentially exist to ensure a known relationship between the centres of consecutive joints. The need for stiff links creates heavy robot mechanisms, large sections of which are passive supporting structures. Although this approach might be essential for many industrial applications where speed of operation and accuracy are paramount, there are many situations where different attributes may provide improved performance. Serpentine robots also utilise discrete joints but combine very short rigid links with a large density of joints. This creates highly mobile mechanisms which appear to produce smooth curves, similar to a snake. Continuum robots do not contain rigid links and identifiable rotational joints. Instead the structures bend continuously along their length via elastic deformation and produce motion through the generation of smooth curves, similar to the tentacles or tongues of the animal kingdom [1].
Abstract
Like the human limbs which inspired them most robots are discrete mechanisms with rigid linb connected by single degree offieedom joints. In contrast ‘continuum’ and ‘serpentine’ robot mechanisms move by bending through a series of continuous arcs producing motion which resembles that of biological tentacles or snakes. This paper provides a single reference to the expanding technology of continuum robot mechanisms. It def2nes the fundamental dl~erence between discrete, serpentine and continuum robot devices; presents the ‘state of the art’ of continuum robots and outlines their areas of application; and introduces some control issues. Finally some conclusions regarding the continued development of these devices are made.

Fig. 2 Intrinsic Planar Actuator The simplest form of continuum actuators are fluid operated planar devices (fig, 2), which require a single pressure input to produce bending in a single plane. The physical construction of the actuator walls determines the motion produced. Typically one side of the elastic actuator has a different axial stiffness to the remaining walls. Increasing internal pressure generates strain variations across the structure and bending occurs. Elasticity causes the device to straighten on decreasing pressure. Several variations exist and a typical application is for compliant fingers, increasing the versatility and error tolerance of grasping end-effecters, whilst minimizing control requirements [2-5], The use of planar continuum mechanisms to transport simple objects within a plane has also been investigated [6-7]. 2.2 Intrinsic Spatial

Continuum Robots - A State of the Art
G. Robinson, J.B.C. Davies Department of Mechanical& Chemical Engineering, Heriot-Watt University, Edinburgh, Scotland, UK
It should be clear that there are fundamental differences in form between conventional discrete, serpentine, and continuum robots (fig. 1). This paper only considers continuum robots.
2 Continuum Robots
Several forms of continuum robot have been developed. These can be broadly classified as ‘intrinsic’, ‘extrinsic’, or ‘hybrid’, according to the method and location of mechanical actuation. In an intrinsic device the actuators are located on and form part of the animated mechanism. Extrinsic devices use remote actuation and motion is transferred into the mechanism via a mechanical linkage. Hybrid devices use a combination of both intrinsic and extrinsic actuation. Each of these groups cart be sub-divided into ‘planar’ or ‘spatial’ devices according to the type of motion produced. Planar devices only move in a single plane of bending, whilst spatial devices can bend in any direction perpendicular to their longitudinal axis. 2.1 Intrinsic Planar

Fig. 4 Actuator Motion intervals about a central longitudinal axis. Internal pressures are controlled to generate extension forces and the structure deforms according to constraints provided by the end forms (fig. 4). It is essential for operation that internal pressures generate axial extension rather than radial expansion and several approaches have been developed to ensure anisotropic elasticity. Devices with many degrees of ti-eedom can be obtained by placing several independent actuators in series. These actuators exhibit passive elastic compliance to external forces in the directions normal to their longitudinal axis. External forces cause compliant motion of the actuator until the force balance within the structure is restored. The resulting increase in strain energy causes the actuator to return to its undisturbed configuration on removal of the external force. Suzumori et al. described the construction and operation of small low pressure silicon rubber actuators (flexible micro-actuator or FMA) ranging from 1-20 mm in diameter [9]. Three parallel chambers were moulded directly into a single cylindrical unit. Integral nylon reinforcing fibres around the circumference of the cylinder resisted radial expansion whilst allowing the actuator to stretch longitudinally. Single stage devices were used as the fingers of a four fingered gripper, whilst a 120 mm long 7 degree of freedom manipulator (including a 1 degree of freedom gripper) was produced using multiple stages. Subsequently FMAs have been used in the construction of mini 6 legged walking robots only 15 mm long [10]. Also stereolithographic techniques have enabled arrays of parallel FMA actuators to be made in a single process. The objective is to manoeuvre objects across the surface of a large FMA array by the distributed actuation of the parallel actuators, in a similar manner to the villi of animal intestines [11]. Davies described a much larger 744 mm long pneumatic device using three parallel thin walled polymeric bellows connected at each end by rigid plates

入舵市安恙阳光实验学校Unit 2 Robots (建议用时:35分钟)Ⅰ.阅读理解A(2020·南昌二模)Robots are now being employed notjust for dangerous tasks, such as discovering mines orrescuing people in disasters. They are also findingapplications as household help and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards them becomes ever more urgent.A team led by Sari Nijssen of Radboud University and Markus Paulus, Professor of Developmental Psychology at LudwigMaximiliansUniversität(LMU), have carried out a study to determine the degree to which people show concern for robots and behave towards them based on moral principles.According to Sari Nijssen, the study set out to answer the following question:“Under what circumstances would adults be willing to sacrifice robots to save human lives?” The participants were faced with a hypothetical(假设的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized to various degrees or a robot that was clearly recognizable as a machine.The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous(无名的) humans.“This result indicates that our study group attached a certain moral status to the robot,” says Paulus. “One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could come into conflict with their intended function—to be of help to us.”【解题导语】本文是一篇说明文。

Abstract Traditionally, robot manipulators have been a simple arrangement of a small number of serially connected links and actuated joints. Though these manipulators prove to be very effective for many tasks, they are not without their limitations, due mainly to their lack of maneuverability or total degrees of freedom. Continuum style (i.e. continuous “backbone”) robots on the other hand, exhibit a wide range of maneuverability, and can have a large number of degrees of freedom. The motion of continuum style robots is generated through the bending of the robot over a given section; unlike traditional robots where the motion occurs in discrete locations, i.e. joints. The motion of continuum manipulators is often compared to that of biological manipulators such as trunks and tentacles. These continuum style robots can achieve motions that could only be obtainable by a conventionally designed robot with many more degrees of freedom. In this paper we present a detailed formulation and explanation of a novel kinematic model for continuum style robots. The design, construction, and

课时达标(三十二) Unit 2 Robots75Ⅰ 阅读理解ATraditionally, robots have been hard, made of metal and other rigid material. But a team of scientists at Harvard University in the US has managed to build an entirely soft robot—one that draws inspiration from an octopus(章鱼).Described in science journal Nature, the “Octobot” could pave the way for more effective autonomous robots that could be used in search,rescue and exploration. “The Octobot is a minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots,” the study's authors wrote.Robots built for precise, repetitive movements in a controlled environment don't do so well on rough terrains(地形) or in unpredictable conditions. And they aren't especially safe around humans, because they're made out of hard and heavy parts that could be potentially dangerous to their users.So researchers have been working on building soft robots for decades. They've taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter.But creating a completely soft robot remains a challenge. Even if engineers build a silicone(硅酮) body, it's still a grand challenge to construct flexible versions of essential parts, such as a source of power.“Although soft robotics is still in its early stage, it holds great promise for several applications, such as searchandrescue operations and exploration,” Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology's Center for MicroBioRobotics, wrote in a comment. “Soft robots might also open up new approaches to improving wellness and quality of life.”语篇导读科学家受到章鱼的启发,制造了软体机器人,本文介绍了这种机器人的研发过程、用处及局限等。
