The purpose of this study is to explore the co-authorship and the hot topic from the most highly cited articles of robots literature. The research targets are 14 journals of robotics from the Science Citation Index Expanded (SCIE) database. A total of 9,571 articles were collected from 1983 to 2009. The conclusions are as follows. The total number of articles from robots literature increased gradually from 96 to 746 each year. The percentage of co-authored articles was 83% and the most frequent numbers of authors per article ranged from 2 to 4. At the national level, the multinational collaboration accounted for 12% of the co-authored articles. The U.S. owned the largest number of multinational collaboration articles and had the highest value of the three chief kinds of centrality measures, which indicated that the U.S. played the key role in controlling resources. However, the portion of multinational collaboration among the co-authored articles for the U.S. (22.79%) was lower than that for Switzerland (48.51%). At the institutional level, about 29% of publications were the result of author collaboration in different institutions. Carnegie Mellon University owned the largest number of inter-institutional collaboration articles. Nevertheless, approximately 86% of the co-authored articles published by Advanced Telecommunications Research Institute International (AIR) in Japan were inter-institutional, which is higher than the percentage of inter-institutional collaboration articles published by any American institutions. In addition, Massachusetts Institute of Technology played the key role in controlling resources. The result of keywords analysis of the most highly cited articles shows 6 major research categories including flexible-path of robot, intelligent robot, vision robot, fixed path or point of mobile robot, time-domain robot, and end-effect robot.
