The Tsinghua University computer is the intelligent automobile topic-based group practises 2007.9- until now
Is engaged in the THMR-V end vehicle to carry the directional antenna to rape the servo-control system and the motion robot end remote control control system research design, primary cognizance control system's hardware circuit design as well as software programming debugging. After Tsinghua University more than one year of exercise, sharpened oneself various aspects ability enormously, had the overall importance assurance to the embedded system development and the control system design, and has formed the immediate reorganization documents habit.
Shandong Scientific and technical university robot Research center 2006.9-2007.6
Is engaged in the laboratory project “the live-wire work robot” multiple spindle movement controller's research design, primary cognizance hardware principle design, PCB plan, as well as software routine debugging. Through this practice, sharpened oneself system debugging ability and independent processing question ability, has raised to the embedded strong interest, sharpened the beginning ability more importantly, strengthened the association team spirit.
