NEW APPROACHES FOR COMPUTING DYNAMIC LOAD-CARRYING CAPACITY OF MULTIPLE cooperating ROBOTIC MANIPULATORS

Chinese Journal of Mechanical Engineering 1998年第2期11卷 67-72页

作者： Yang Yulin Lu Ling Zhao Yongsheng Zhou Yulin Yanshan University Yanshan Univ China

A novel unified method for computing the dynamic load carrying capacity(DLCC) of multiple cooperating robotic manipulators is *** this method,the kinematic constraints and the governing dynamic equations of the multiple robot system are formulated in the joint space by using the method of transference of dependence from one set of generalized coordinates to another,and the virtual work principle,which includes the readily available dynamics and joint torques of individual manipulators,and the dynamic of *** on this dynamic model,the upper limit of the DLCC at any points on a given trajectory is obtained by solving a small size linear programming *** method is conceptually straightforward,and it is applicable also to the cases of multi fingered robot hands and multi legged walking machines.

Dual Dynamic PTZ Tracking Using cooperating Cameras

引用

Intelligent Control and Automation 2015年第1期6卷 45-54页

作者： Mohammed A. Eslami John R. Rzasa Stuart D. Milner Christopher C. Davis Department of Electrical and Computer Engineering University of Maryland College Park USA

This paper presents a real-time, dynamic system that uses high resolution gimbals and motorized lenses with position encoders on their zoom and focus elements to “recalibrate” the system as needed to track a target. Systems that initially calibrate for a mapping between pixels of a wide field of view (FOV) master camera and the pan-tilt (PT) settings of a steerable narrow FOV slave camera assume that the target is travelling on a plane. As the target travels through the FOV of the master camera, the slave cameras PT settings are then adjusted to keep the target centered within its FOV. In this paper, we describe a system we have developed that allows both cameras to move and extract the 3D coordinates of the target. This is done with only a single initial calibration between pairs of cameras and high-resolution pan-tilt-zoom (PTZ) platforms. Using the information from the PT settings of the PTZ platform as well as the precalibrated settings from a preset zoom lens, the 3D coordinates of the target are extracted and compared to those of a laser range finder and static-dynamic camera pair accuracies.

Unpacking Misconceptions

Beijing Review 2019年第18期62卷 20-21页

作者： Wang Peng the Chongyang Institute for Financial Studies Renmin University of China the Charhar Institute Renmin University of China

China has always looked to cooperating with rather than dominating other countries The Second Belt and Road Forum for International Cooperation held in Beijing on April 25-27 was a milestone for the Belt and Road Initiative along with international development and global ***,it is undeniable that there are still a few misperceptions and misunderstandings about the initiative or other key topics related to China that are in urgent need of clarifi *** example,whether China is utilizing the Belt and Road Initiative to pursue its“sharp power”is one of the most heated topics.
