How can robots break through the underlying technical barriers?

Hardware equipment session: how robots can break through the underlying technical barriers

The guests participating in this dialogue are: Song Gaosheng, Technical Director of Mitsubishi Electric Semiconductor Greater China, Ji Shuting, Deputy Dean of the Intelligent Transmission Technology Research Institute of Zhitong University, Gui Xinfei, Deputy General Manager of Benrun Harmonic, Tang Weiwei, Senior Director of Bitmain, Miao Yuqun, general manager of Daru Technology.

The underlying technology is often the place where the barriers are concentrated, which has caused the gap between domestic and foreign brand industrial robots. The opening of the underlying technology plays a vital role in the improvement of robot performance indicators.

Song Gaosheng believes that the servo drive is the core component of the robot, and the power semiconductors hidden in it play a key role in the performance of the servo drive. In the iterative upgrade of power semiconductor products, higher junction temperature and lower electromagnetic noise are its eternal pursuit. At present, Mitsubishi Electric's latest seventh-generation products have improved their junction temperature and electromagnetic noise performance, but they are far from enough. The strict material requirements of semiconductor products have led to a slower cost reduction, and noise control is still in iteration, which has become a challenge facing power semiconductors.

Ji Shuting pointed out that the current technical bottleneck in the RV reducer industry is mainly accuracy retention and life issues. For Zhitong, these two hard bones have been gnawed down. The next problem is how to rapidly expand production and make the market accept us. Zhitong`s development goal is to keep up with foreign mainstream products until it leads the RV reducer market.

Gui Xinfei said that as the application range of harmonic reducers becomes wider and wider, its application in harsh environments is facing challenges. How to make improvements in materials and processes so that the reducer can cope with various harsh working environments is a technical problem.

Tang Weiwei said that the global semiconductor market is currently very competitive, and Bitmain has advanced chip manufacturing capabilities, 7nm, 5nm and even 3nm in the future. Performance and power consumption are the eternal pursuit of semiconductors, which can make the robot "brain" smarter.

Miao Yuqun pointed out, "My idea is very simple for the breakthrough of the underlying technology. The first is "Tian Ji Horse Racing", to fully identify his own advantages; the second is to have a specialization in the technical industry and continue to do well in the depths. Own business; the third is to insist on cooperation and win-win, insist on doing everything, often do nothing well, just like Daru Technology, only focus on the polishing field."
