Gesture Recognition is the most recent development in the field of Bio Robotics. The proposed paper focuses on presenting a low cost sensor based human gesture recognition for the game of Hand Cricket. Hand cricket is a popular game in south Asian countries which involves the use of human finger gestures to score. This game is generally played between two players. Each player has a pre-defined gestures for the scores one, two, three, four and six. Both the players are made to wear the Myo armband. Myo armband is used to capture the Bio-potentials triggered during every muscle action. The various gestures performed in this game triggers various muscle group signals. A data set is created by collecting the eight channel bio potentials for every gesture made by both the players. The obtained data set is pre-processed and feature extracted. Now the Machine Learning techniques are performed in the data set to classify all the five different gestures with maximum accuracy. Support Vector Machine (SVM) gave the maximum accuracy to the classify the data set of both the players. The efficiency obtained for both the players are 92% and 84%. The proposed system is made to train with the data set obtained by the two players and the game is played in real time with the help of two MATLAB in two computers. Along with the classification of data, the scores of the individual player is calculated and displayed. With the scores being displayed, we can determine the player who scored the highest and the winner of the game can be determined.
手势识别是生物机器人领域的最新发展。提出了一种低成本的基于传感器的手部板球人体手势识别方法。手板球在南亚国家是一种流行的游戏,它涉及到使用人类手指的手势来得分。这种游戏通常是两个人玩的。每个玩家对于分数1、2、3、4和6都有预先定义的手势。两名球员都被要求佩戴Myo臂章。Myo臂带被用来捕捉每一个肌肉动作中触发的生物电位。在这个游戏中,不同的手势会触发不同的肌肉群信号。一个数据集是通过收集两个玩家的每个手势的8个通道生物电位来创建的。对得到的数据集进行预处理和特征提取。现在在数据集中执行机器学习技术,以最大的准确性对所有五种不同的手势进行分类。支持向量机(SVM)对两种玩家的数据集都给出了最大的分类精度。双方的效率分别为92%和84%。该系统利用两名棋手获得的数据集进行训练,并在两台计算机上使用两个MATLAB进行实时比赛。随着数据的分类,个人球员的分数被计算和显示。随着分数的显示,我们可以确定得分最高的玩家,并确定游戏的赢家。

Home appliance manufacturing involves a lot of human operations due to variety of products and sizes, and lower cost requirements. Applying traditional inspection solutions to home appliances faces three challenging issues: 1)hard to handle different sizes of objects from big refrigerators to small kettles with fixed camera setting; 2)heavy engineering and tuning work for different inspection tasks; 3)high cost of stand-alone inspection system. This paper proposes a camera mounted robot solution with self-learning and edge/cloud visual inspection architecture. Firstly the 4 DoF robot arm with novel controlling strategy uses a single camera to handle variety of objects. For different inspection tasks, a machine learning based approach removes the complicated and tedious works for engineering and parameter tuning. Lastly, an edge/cloud computing framework puts limited tasks on cheap edge devices at manufacturing side and reduces the total cost.
家电制造由于产品和尺寸多样,成本要求较低,涉及大量的人工操作。将传统的检测方案应用到家电产品中,面临着三个挑战:1)从大的冰箱到小的相机设置固定的水壶,难以处理不同尺寸的物体;2)针对不同检测任务的繁重工程和调试工作;3)单机检测系统成本高。本文提出了一种基于自学习和边缘/云视觉检测架构的摄像机机器人解决方案。首先,采用新颖控制策略的四自由度机械臂采用单摄像头处理多种目标。对于不同的检测任务,基于机器学习的方法消除了复杂而繁琐的工程和参数调整工作。最后,边缘/云计算框架将有限的任务放在制造端的廉价边缘设备上,并降低了总成本。

The outstanding swim characteristics of the frog have inspired the development of artificial robotic swimmer, featuring synchronous swim capabilities, which could be of significant engineering interest in underwater applications. The Underwater synchronous swim is challenging because drag on the oars increases as the square of their speed. In frogs, as leg muscles shorten faster, the force capacity falls and drag force increases. In this paper, key features of frog's synchronous swim are reproduced by running 2D simulations which fully exploit the Fluid-Structure Interaction interface of COMSOL. Velocity, displacement, lift and drag forces in 2D space are studied. Unlike previous FSI underwater robotics studies in which much efforts are put on fluid dynamics, here muscles contraction is simulated by using the notion of pre-strain, emphasizing the kinematical role of muscle and the generation of movement. Based on these parameters, a soft frog robot embedded with shape memory alloy is fabricated using multilayer 3D printing technology. Flex Sensor encapsulated with Atomic Layer Deposition (ALD) is included in the limbs of soft frog robot to read the angle in real time. A proper synchronous movement of a frog-like body is reproduced by defining the pattern of muscles activation.
青蛙出色的游泳特性激发了人工机器人游泳者的发展,具有同步游泳能力,这可能是水下应用的重要工程兴趣。水下同步游泳是具有挑战性的,因为桨上的阻力随着速度的平方而增加。青蛙的腿部肌肉缩短得越快,力的承受能力就会下降,阻力就会增加。本文充分利用COMSOL的流固耦合界面,通过二维仿真再现了青蛙同步游动的关键特征。研究了二维空间中的速度、位移、升力和阻力。与以往的FSI水下机器人研究不同,在这些研究中,很多努力都放在流体动力学上,这里的肌肉收缩是通过使用预应变的概念来模拟的,强调肌肉的运动学作用和运动的产生。基于这些参数,采用多层3D打印技术制作了嵌入形状记忆合金的软蛙机器人。柔性传感器采用原子层沉积(ALD)封装在软蛙机器人的四肢上,可以实时读取角度。通过定义肌肉激活的模式,再现了青蛙样身体的适当同步运动。

Emerging through an industry-academia collaboration between the University of Sheffield and VBC Instrument Engineering Ltd, a proposed robotic solution for remanufacturing of jet engine compressor blades is under ongoing development, producing the first tangible results for evaluation. Having successfully overcome concept adaptation, funding mechanisms, design processes, with research and development trials, the stage of concept optimization and end-user application has commenced. A variety of new challenges is emerging, with multiple parameters requiring control and intelligence. An interlinked collaboration between operational controllers, Quality Assurance (QA) and Quality Control (QC) systems, databases, safety and monitoring systems, is creating a complex network, transforming the traditional manual re-manufacturing method to an advanced intelligent modern smart-factory. Incorporating machine vision systems for characterization, inspection and fault detection, alongside advanced real-time sensor data acquisition for monitoring and evaluating the welding process, a huge amount of valuable industrial data is produced. Information regarding each individual blade is combined with data acquired from the system, embedding data analytics and the concept of “Internet of Things” (IoT) into the aerospace re-manufacturing industry. The aim of this paper is to give a first insight into the challenges of the development of an Industry 4.0 prototype system and an evaluation of first results of the operational prototype.

Monocular vision-based motion capture system: A performance model 基于单目视觉的动作捕捉系统:一种性能模型

We propose a performance model for a monocular vision-based motion capture system. Such a system can use uniquely patterned augmented reality (AR) markers worn on the body. Two key factors in evaluating such a system are tracking accuracy and blurring effects. Past work involving AR markers has emphasized other factors such as detection rate or pixel error. In cases where accuracy has been studied, it has been done only for specific systems. In contrast, our model is more general and can accommodate different types of cameras and marker sizes. Our model can also simulate a marker worn on a moving limb. Preliminary experiments show that our model has the potential to accurately predict real-world performance.
我们提出了一种基于单目视觉的运动捕捉系统的性能模型。这种系统可以使用佩戴在身体上的独特模式增强现实(AR)标记。评估这种系统的两个关键因素是跟踪精度和模糊效果。过去涉及AR标记的工作强调了其他因素,如检测率或像素误差。在研究准确性的情况下,只针对特定的系统进行了研究。相比之下,我们的模型更通用,可以适应不同类型的相机和标记尺寸。我们的模型还可以模拟佩戴在移动肢体上的标记。初步实验表明,我们的模型具有准确预测现实世界性能的潜力。

In caring for special needs children, for example, those with autism, there should be alternatives for the parents and guardians of these children. In this instance, aside from fellow humans, care robots should be considered. Therefore, this review paper synthesizes the results from several primary literature on the feasibility of using robots to care for children with special needs. Digesting and summarizing on the literature reviewed within this scope, it is not currently feasible for robots to care for children much so for those with special needs. More concrete evidences are required for parents and guardians to put faith in a machine as a replacement for a human care giver.
在照顾有特殊需要的儿童时,例如,那些患有自闭症的儿童,这些儿童的父母和监护人应该有其他选择。在这种情况下,除了人类同胞,还应该考虑护理机器人。因此,这篇综述文章综合了几篇关于使用机器人照顾特殊需要儿童的可行性的主要文献的结果。消化和总结在这个范围内回顾的文献,目前机器人照顾儿童是不可行的,照顾有特殊需要的人更是不可行的。父母和监护人需要更多具体的证据来相信机器可以取代人类照顾者。

A decision making model for ethical (ro)bots 伦理机器人的决策模型
Pub Date : 2017-10-01 DOI: 10.1109/IRIS.2017.8250122
F. Alaieri, André Vellino
Autonomous bots and robots (we label “(ro)bots”), ranging from shopping assistant chatbots to self-driving cars are already able to make decisions that have ethical consequences. As more such machines make increasingly complex and significant decisions, we need to know that their decisions are trustworthy and ethically justified so that users, manufacturers and lawmakers can understand how these decisions are made and which ethical principles were brought to bear in making them. Understanding how such decisions are made is particularly important in the case where a (ro)bot is a self-improving, selflearning type of machine whose choices and decisions are based on past experience, given that they may not be entirely predictable ahead of time or explainable after the fact. This paper presents a model that decomposes the stages of ethical decision making into their elementary components with a view to enabling stakeholders to allocate the responsibility for such choices.
从购物助理聊天机器人到自动驾驶汽车,自主机器人和机器人(我们称之为“(非)机器人”)已经能够做出具有道德后果的决定。随着越来越多这样的机器做出越来越复杂和重要的决定,我们需要知道它们的决定是值得信赖的,在道德上是合理的,这样用户、制造商和立法者才能理解这些决定是如何做出的,以及在做出这些决定时遵循了哪些道德原则。如果机器人是一种自我改进、自我学习的机器,它的选择和决定都是基于过去的经验,因为它们可能无法完全提前预测,也无法在事后解释,那么理解这些决定是如何做出的就显得尤为重要。本文提出了一个模型,该模型将道德决策的各个阶段分解为其基本组成部分,以使利益相关者能够分配这些选择的责任。

Implementation and control for an MDOF cable-suspended parallel robot 多自由度悬索并联机器人的实现与控制
Pub Date : 2017-10-01 DOI: 10.1109/IRIS.2017.8250145

In this work, a multi-degrees-of-freedom (MDOF) cable-suspended robot that can perform pick-up-and-place tasks in large workspaces with weighty loads is designed. The proposed cable-suspended parallel robot comprises a rigid frame and an end-effector that is suspended from eight cables — four upper cables and four lower cables. The lengths of the cables are computed from the given positions of the suspended end-effector using a kinematic model. However, most multicable-driven robots struggle with interference among the cables, requiring a complicated control methodology to find a target goal. Owing to this issue with cable-driven parallel robots, the whole control structure decomposes positioning control missions and allocates them into upper- and lower- level. The upper-control is responsible for tracking the suspended endeffector to the target region. The lower-level control makes fine positional modifications. Experimental results demonstrate that the hybrid control mode significantly improves positioning performance. The broad variety of issues that are presented in this work apply to aerostats, towing cranes, locomotion interfaces, and large-scale manufacturing that require cable- suspended parallel robots.
在这项工作中,设计了一种多自由度(MDOF)悬索机器人,可以在大型工作空间中执行重负载的拾取和放置任务。所提出的悬索并联机器人包括一个刚性框架和一个悬挂在八根电缆上的末端执行器——四根上电缆和四根下电缆。缆绳的长度是用运动学模型从悬挂末端执行器的给定位置计算出来的。然而,大多数多电缆驱动的机器人都在与电缆之间的干扰作斗争,需要复杂的控制方法来找到目标。针对缆索驱动并联机器人的这一问题,整个控制结构将定位控制任务分解并划分为上下两层。上层控制负责跟踪悬浮的效应器到目标区域。低级控件进行精细的位置修改。实验结果表明,该混合控制模式显著提高了定位性能。在这项工作中提出的各种各样的问题适用于浮空器、牵引起重机、运动接口和需要缆索悬挂并联机器人的大规模制造。

The transport industry is subject to a lot of improvement aiming to autonomous transportation systems. Railway is also concerned. An autonomous vehicle must be able to perceive and analyze its environment with a view to being able to adapt its driving. In this paper we focus on the wheel-rail contact analysis, and the adherence evaluation, as it conditions loads of variables such as braking, traction and maximum speed. It also has an impact on security distance between trains. Adherence can be degraded by the presence of pollution on the rail surface. We present an imaging system, using a multispectral camera, capable of detecting and recognizing pollutant. The pollution is then associated to an adherence coefficient.
为了实现自动运输系统,交通运输业需要进行大量改进。铁路也受到关注。自动驾驶汽车必须能够感知和分析其环境,以便能够适应其驾驶。在本文中,我们着重于轮轨接触分析和附着性评价,因为它的条件载荷变量,如制动,牵引力和最大速度。它还会对列车之间的安全距离产生影响。钢轨表面的污染会降低附着力。我们提出了一种多光谱相机成像系统,能够检测和识别污染物。然后将污染与附着系数联系起来。

Robots are being deployed in a wide range of smart environments that are equipped with sensors and actuators. These devices can provide valuable information beyond the perception range of a robot's on-board sensors, or provide additional actuators that can complement the robot's actuation abilities. Traditional robot task planners do not take these additional sensor and actuators abilities into account. This paper introduces an enhanced robotic planning framework which improves robots' ability to operate in dynamically changing environments. To keep planning time short, the amount of knowledge in the planner's world model is minimized.
机器人被广泛部署在配备传感器和执行器的智能环境中。这些设备可以提供有价值的信息,超出了机器人的车载传感器的感知范围,或者提供额外的执行器,可以补充机器人的驱动能力。传统的机器人任务规划没有考虑到这些额外的传感器和执行器的能力。本文介绍了一种改进的机器人规划框架,提高了机器人在动态变化环境中的操作能力。为了保持计划时间短,计划者世界模型中的知识量被最小化。
