查询词典 obstacles

Aiming at the dynamic nonhomogeneity and kinematic redundancy, making reference to the actions of human beings, we propose a new hierarchical approach of coordinated path planning for mobile manipulateors, and a dynamic weighting strategy, which can avoid obstacles and get the best results of optimization.

With experience points, followed by two chest and I together, in the open to lock the first and second lock at all times to smoothly open the lock when the third one of the obstacles to trigger chest and run tasks, The obstacle race and the first place is not the same as there is a mischievous little devil and the devil beetles, feeling the ground floor of this little devil than an obstacle to run easier, less than two minutes to finish, almost no trouble.

有了点经验之后，随后的两个宝箱我一起做，在开第一把锁和第二把锁的时候都顺利，开第三把锁的时候其中一个宝箱又触发了障碍跑任务，这次障碍跑和第一次不一样的地方是里面是调皮小鬼和魔甲虫，感觉这个比有地下小鬼的障碍跑容易多了，不到两分钟就做完，几乎没费事。

As one part of the project, the dissertation is developed with thelocalization problem in mobile robot navigation. Combined with "MobileRobot 1 of Central South university (MORCS-1)", a mobile robot designed byus that equipped with a 2D laser measurement system to sense the environmentand the proprioceptive sensors such as the odometry, gyroscope to calculate itsdead reckoning, the approach about the four kind uncertainty factors of mobilerobot localization is studied. These researches include that the error analysisand calibration of position sensors is implemented to reduce the measurementnoise, the 3D kinematic model of mobile robot is built to gain the accuratepose in complex terrain, some work on the automatic detection of static ordynamic obstacles based on laser scanner is investigated to eliminate thedynamic influence of the environment and to realize the reliably absoluteposition, and lastly a robust algorithm is presented to involve the incrementalenvironment mapping and self-localization of mobile robot with unknown dataassociation and to improve the self-localization performance of mobile robotunder unknown environment.

作为该项目研究的一部分，本论文以移动机器人导航中的定位问题为研究内容，利用自行研制的装配有二维激光雷达环境感知系统，并通过里程计、陀螺仪等内部传感器来实现航迹推测的移动机器人"中南移动1号MORCS-1"，重点围绕影响移动机器人系统定位的四类不确定性处理展开研究：通过移动机器人定位传感器的误差分析及校准，旨在消除传感器噪声所带来的测量误差；通过建立移动机器人的三维运动学模型进行航迹推测，以期实现复杂地形下精确的移动机器人本体姿态感受；通过基于激光雷达的动静态障碍的自主检测等相关研究，尽量消除环境的不确定因素影响进而实现可靠的移动机器人绝对定位；通过以上研究，针对未知数据关联下移动机器人增量式环境建图与自定位的研究提出一种鲁棒的滤波算法，改善未知环境中移动机器人自定位的性能。

所有的障碍是没有危险，如果你是飞行家跟踪您的学校。

It seemed to me that the roots of the problem were these: the White House staff had too little experience in, and too few connections with, Washington's established power centers; we were trying to do too many things at once, creating an impression of disarray and preventing the people from hearing what we had actually accomplished; our lack of a clear message made otherwise minor issues look as if I was governing on the cultural and political left, not from the dynamic center, as I had promised; the impression was being reinforced by the one-note Republican attack that my budget plan was nothing but a big tax increase; and I had been blind to the considerable political obstacles I faced.

我觉得，问题的根源似乎有这么几个：白宫工作人员与华盛顿早已确立的权力中心打交道的经验太少，与它们建立的联系也过少；我们试图同时开展很多计划，让人觉得没有秩序，使人民无从得知我们实际取得的成绩；我们传达的信息不够明确，在一些别的方面较小的问题上，我显得是站在文化及政治左派的立场来管控，而不是像许诺过的那样，走具有活力的中间路线；共和党一成不变的抨击强化了这种印象，他们说我的预算方案只不过是一个大幅增税的方案；而且我没有看到自己所面对的不小的政治障碍。
