The attitude control of intelligent heavy machinery poses a challenge to the robustness, anti-interference and algorithm of attitude sensing systems. Therefore, this project intends to develop a MEMS attitude sensing system with high impact resistance and high precision and apply it to excavators as a typical application scenario to verify the feasibility of the sensing system. Our team has many years of experience in the field of micro-electro mechanical sensors, integrated sensing systems and sensing algorithms. This is a competitive team composed of young scientists and serial entrepreneurs to ensure the success of our project.
