Incorporating a third CCD camera into a conventional binocular is verified to be very helpful to solve translational motion. The extra device not only provides more image information, but also plays a significant role regarding the solution issue. In this paper, a novel algorithm to recover parameters for translational motion using such a parallel trinocular system is presented. This approach overcomes the difficulty of matrix singularity happened in binocular. In order to fit into application requirements, a compact close form solution is also derived. This solution owns some important features, such as no matrix manipulation, no danger of matrix singularity, and easy to apply. To validate this close form solution, extensive experiments were conducted It is concluded that the movement magnitude in the depth direction has great influence on the estimation performance of the translational motion. Simulations in a perturbed environment are also performed to study the effect of possible image uncertainty. Compared with a conventional binocular, the presented parallel trinocular system demonstrates excellent performance on recovering parameters of translational motion under the circumstance of limited motion along the depth direction.
在传统的双筒望远镜中加入第三个CCD相机被证明是非常有助于解决平移运动的问题。额外的设备不仅提供了更多的图像信息,而且在解决方案问题方面起着重要的作用。本文提出了一种利用并联三视系统恢复平移运动参数的新算法。该方法克服了双目成像中矩阵奇异的困难。为了适应应用需求,还推导了一个紧凑的闭合形式解。该方法具有不需要对矩阵进行操作、不存在矩阵奇异危险、易于应用等重要特点。为了验证这一近似解,进行了大量的实验。结果表明,深度方向的运动幅度对平移运动的估计性能有很大影响。在摄动环境下进行了模拟,研究了可能的图像不确定性的影响。与传统双目系统相比,该系统在深度方向运动受限的情况下,具有良好的平移运动参数恢复性能。

Adaptiveness is one of the target functions of research on autonomous robotic systems. However, the adaptiveness realized in the robotic research so far is quite limited and specific to sample problems and systems configurations. On the other hand, all the animals from primitive ones to insects or mammals have commonly the adaptiveness to behave in an unexpected environment. Such adaptive behaviors are the intelligent sensory-motor functions, and most essential and indispensable ones for animals to survive. It must be effective to consult biological systems to find the general design principle to realize the adaptiveness in artificial systems as well as robotic systems. However, the secret of the mechanism to realize the adaptiveness in animals is not yet thoroughly revealed even in biology as well as brain science and neurophysiology. Such an adaptive function is considered to emerge from the interaction of the body, brain, and environment, which is caused by a subject to act or move. We call the intelligence for generating adaptive motor function mobiligence. The Mobiligence project started from 2005, which was accepted as a five-year program of Scientific Research on Priority Areas of Grant-in-Aid Scientific Research from the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT). The present project is designed to investigate the mechanisms of mobiligence by collaborative research in biology and engineering from systematic and synthetic (constructive) approach. In this talk, the abstract of the project is introduced in contrast to adaptive behaviors achieved in the robotic research so far.
自适应是自主机器人系统研究的目标函数之一。然而,迄今为止,机器人研究中所实现的自适应能力非常有限,并且仅限于样本问题和系统配置。另一方面,从原始动物到昆虫或哺乳动物,所有的动物都具有在意想不到的环境中行为的普遍适应性。这种适应行为是智能的感觉运动功能,是动物生存最基本、最不可缺少的功能。要实现人工系统和机器人系统的自适应,必须有效地借鉴生物系统来寻找通用的设计原则。然而,即使在生物学、脑科学和神经生理学中,实现动物适应性的机制的秘密也尚未完全揭示。这种自适应功能被认为是由主体的行为或移动引起的身体、大脑和环境的相互作用产生的。我们称之为产生适应性运动功能的智能。Mobiligence项目始于2005年,是日本文部科学省(MEXT)接受的关于科学研究资助优先领域的五年科学研究计划。本项目旨在通过生物学和工程学的合作研究,从系统和综合(建设性)的方法来研究移动性的机制。在这个演讲中,介绍了项目的摘要,并与迄今为止机器人研究中取得的自适应行为进行了对比。

In this paper, we investigate visual tracking of multiple biomimetic robotic fish which swim together to achieve some specific tasks in underwater cluttered environments. Taking account of surrounding background and kinematic characteristics of swimming fish, a novel color-index-based identification approach is presented, which is capable of identifying many fish rapidly in a processing cycle. Meanwhile, some anti-jamming measures including optical correction and foil superposition are made to ensure a robust tracking. Finally, all tracking operations are optimized in coding with the aid of parallelized SIMD technologies embedded in processors. Our proposed visual system can experimentally track as large as an amount of eight robotic fish and one obstacle within 24.143 milliseconds, which can fully satisfy the requirements of cooperative control.

In this paper, a computational method for obtaining maximum dynamic load carrying capacity (DLCC) for the 6-UPS Stewart platform manipulator is developed. In this method, the manipulator is supposed to be a flexible manipulator and the joint actuator torque capacity and accuracy of motion are considered as the major limiting factors in determining the maximum payload. The maximum dynamic payload carrying capacity of manipulator is presented while dynamic model of a typical hydraulic actuator is used in the joint actuator force capacity for a given trajectory. Effects of flexibility of prismatic joints are considered in static situation to show considerable effects of joint's deflection on motion accuracy of 6UPS-Stewart platform. This method can be used for determining the maximum dynamic payload which acting on end-effector for mechanical design of manipulator and optimized selection of actuator, such as machine tools based on hexapod mechanism.

A tele-rehabilitation system is introduced in this paper. The system consists of a master system and a slave system. The master system includes a haptic device (PHANTOM Omni), and the slave system includes a 6-DOF robot arm. The patient hand is fixed to the robot arm, so the therapist can move the patient hand along the predefined track through tele-operation. According to the vision feedback and force feedback, the therapist can adjust his operation. Furthermore, a force tracking experiment has also been performed, and the tracking result can be used to appraise the tele-rehabilitation performance. From the tele-operation experimental result, we can see that the system has good operability, and the agility of upper limbs has been improved greatly.

Effect of an oscillatory motion of a manipulator on large force generation is investigated in this paper. Two methods for oscillating a manipulator are examined using simulations. One of the methods simply produces a harmonic wave as a command for a manipulator. When the frequency of the harmonic wave is appropriately adjusted, the manipulator produces a larger force than a manipulator driven by a traditional command. However, this method needs a big power motor for joint driving. To reduce the power of motor, the other method uses a nonlinear oscillator that has a frequency entrainment property. The entrainment property effects reduction of necessary power to oscillate a manipulator.

There are Gauss noise and impulse noise in the great mass of the input images of the robot vision system simultaneously. And it is difficult to get rid of Gauss noise and impulse noise only by traditional filter at the same time. Based on analyzing traditional filter algorithm, the adaptive-fuzzy algorithm is adopted in this paper. Firstly, the algorithm demarcates impulse noise and separates the two kinds of noise in each part by noise detection. Then the adaptive median filter is applied to remove the impulse noise. Based on filtering the impulse noise, combining histogram and membership function in fuzzy control, a new algorithm is given to filter Gauss noise. Finally there is a brachylogy algorithm for median filter to improve the practicability. In real time application on robots, the new filter method shows better locating performance than traditional algorithm in real time image with Gauss noise and impulse noise.
机器人视觉系统的大量输入图像中同时存在高斯噪声和脉冲噪声。传统的滤波方法很难同时去除高斯噪声和脉冲噪声。本文在分析传统滤波算法的基础上,采用自适应模糊算法。该算法首先对脉冲噪声进行标定,并通过噪声检测将各部分的两种噪声分离出来;然后采用自适应中值滤波去除脉冲噪声。在过滤脉冲噪声的基础上,结合模糊控制中的直方图和隶属函数,提出了一种过滤高斯噪声的新算法。最后提出了一种近距离中值滤波算法,提高了算法的实用性。在机器人的实时应用中,该滤波方法在含有高斯噪声和脉冲噪声的实时图像中显示出比传统算法更好的定位性能。

We present simultaneous estimating the position and the mechanical impedance of unknown surfaces using a new robotic finger. Successfully treating such a simultaneous sensing device will contribute to reducing the inspection time required for industrial products, and could also be useful for detecting unknown surfaces such as in disaster zones. We propose a new robotic finger that is equipped with a force sensor and a resonant mechanical element on its fingertip. The force sensor is used as a surface detector to sense the reaction force from unknown surfaces, and the resonant mechanical part acts as a scaling amplifier to estimate the mechanical impedance of unknown surfaces. We verify the usefulness of our robotic finger by experiments.

Mobile Robots Odor Localization with an Improved Ant Colony Algorithm 基于改进蚁群算法的移动机器人气味定位
Pub Date : 2006-12-17 DOI: 10.1109/ROBIO.2006.340358
Qing-Hao Meng, Juncai Li, Fei Li, M. Zeng
An improved ant colony algorithm (ACA) is put forward to solve the mobile robot odor localization (MROL) problem. The so-called MROL means localizing an odor source with mobile robots. The improved algorithm is realized through three phases, which are genetic algorithm (GA) based local search, global search and pheromone update. The GA ensures that the optimal or sub-optimal points can be found within local areas. The global search phase consists of random and probability based searches. The random search can prevent the ACA from getting into local optimum. Detailed implementation procedure of the improved ACA for the MROL is presented. Two Gaussian concentration models are used to describe the odor distribution. Simulation results show that the robots can asymptotically approach and finally determine the odor source.

Despite the fact that a running legged robot can be simply modeled by a spring loaded inverted pendulum and that the trajectory of its center of gravity is approximated as a ball on the rebound, the motions of its swinging leg and supporting leg are very important to run stably. In many previous works, trajectories of legs could easily deviate from their workspace of legs and thus make the robots unstable. In this paper, for stability in running, we propose a method to generate trajectories of legs based on an ellipse and to modify joint angles and angular velocities of the legs during touchdowns and take-offs depending on the running speed. To evaluate the performance and the effectiveness of this method, a series of computer simulation of a galloping 4-legged robot in the sagittal plane are performed. Their results show that the proposed method is effective in generating stable galloping locomotion.
尽管有腿的跑机器人可以简单地用弹簧加载的倒立摆来建模,其重心轨迹可以近似为一个反弹的球,但其摆动腿和支撑腿的运动对其稳定运行是非常重要的。在以往的许多研究中,机器人腿的运动轨迹很容易偏离其工作空间,从而导致机器人不稳定。为了提高跑步的稳定性,我们提出了一种基于椭圆的腿轨迹生成方法,并根据跑步速度调整腿着地和起飞时的关节角度和角速度。为了评估该方法的性能和有效性,对一个四足机器人在矢状面上的奔跑进行了一系列的计算机仿真。结果表明,该方法能有效地产生稳定的奔驰运动。
