On this day, 38 years ago, on December 18, 1987 (October 28, 1987, the lunar calendar), my country made the first fully domestically produced robot. After the operator issues instructions through the keyboard, the orange robot freely rotates and retracts its arms to quickly and accurately perform arc welding on a steel plate. This Yegang No. 1 robot, which performed gracefully and freely, passed the ministerial appraisal in Beijing on December 18, 1987. Automatic control experts who participated in the appraisal believe that Yegang No. 1 robot is the first fully domestically produced robot in my country. For the more than 100 robots manufactured before this, the software and some hardware of the control systems were imported from abroad. After four years of hard work by scientific researchers at Beijing Iron and Steel Institute, all the hardware, software, and anti-vibration control of this robot have been localized. All functional and technical indicators have reached the level of similar products in the world in the 1980s, filling my country's industrial robot control system. Technical gaps.
