New breakthrough in gallium nitride technology: release of the first domestically produced humanoid robot joint magnetic encoding chip

China's 15th Five Year Plan has made clear arrangements for key industries such as integrated circuits, intelligent robots, and wide bandgap semiconductors. In order to implement the requirements of national industrial development, break through the bottleneck of core perception and control technologies for humanoid robots, and promote the high-quality development of embodied intelligence industry, Zhongke Wireless Semiconductor recently officially released the first gallium nitride (GaN) magnetic coding chip for humanoid robot joints in China. This achievement marks China's independent and controllable development in the fields of high-end robot sensors and wide bandgap integrated circuits, completing an important leap from catching up to local leadership, and providing hardcore support for cultivating new quality productivity and seizing the commanding heights of future industries. Currently, China is making every effort to promote the research and development of core technologies such as artificial intelligence and high-end equipment, and focusing on improving the independent and controllable level of the industrial and supply chains. The joint servo system of humanoid robots has long been constrained by bottlenecks such as high temperature, accuracy, volume, and dynamic performance. Traditional sensors suffer from high-temperature degradation, and core components rely heavily on imports. The CT-21X series chips launched this time are fully independently developed by the enterprise. As the first innovative entity in China to achieve mass commercial use of gallium nitride logic inverter integrated circuits, Zhongke Wireless Semiconductor has dozens of GaN core invention patents, covering the entire chain of materials, devices, processes, and packaging, and building independent and controllable intellectual property and technical barriers.

The first domestically produced GaN magnetic encoding chip for humanoid robot joints has been released, reconstructing a new benchmark for high-precision motion control

Recently, Zhongke Semiconductor officially released the first gallium nitride (GaN) magnetic encoder sensor for humanoid robot joints in China. Relying on the high sensitivity, high radiation, high frequency, and high temperature stability characteristics of GaN 2DEG, it achieves core indicators such as angle accuracy, temperature drift, bandwidth, and power consumption that are fully ahead of traditional TMR sensors under extreme working conditions of 180 ℃. It solves the four major industry pain points of severe heat generation, limited space, insufficient lightweight, and high precision in humanoid robot joints, providing a new generation of localized, highly reliable, and miniaturized position sensing core solution for high-performance servo joints.
