1978年初,我所接受一机部科技司下达的科研项目——机械手样机的研制,经过三年多时间的努力工作,完成了5公斤通用机械手样机的研制任务。1981年6月底经所级签定后,对该样机作了改进并进行了实验室考核,性能稳定。同年12月17日由省机械工业厅邀请了国内从事机械手研制16个有关单位,在南京组织了签定。一致认为: At the beginning of 1978, I accepted the research and development of a robotic prototype of a scientific research project issued by the Department of Science and Technology of the Ministry of Machines. After more than three years of hard work, we completed the task of developing a prototype of a 5 kg general robot handpiece. After the signing at the end of June 1981, the prototype was improved and the laboratory examination was performed. The performance was stable.
