In　order　to　get　the　information　close　to　the　regulation　of　movement　of　the　human　lower　limbs,　a　multichannel　information　acquisition　project　is　put　forward　for　the　human　lower　limbs　joints　motion.　This　project　can　achieve　a　higher　compatibility,　more　appropriate　human　body　motion　rules　for　lower　limbs　rehabilitation　robots　design　and　research.　Based　on　the　technologies　of　FPGA,　USB2.0　interface　and　LabVIEW,　a　set　of　human　lower　limbs　motion　information　acquisition　system　is　designed　with　characteristics　of　high　performance,　low　power　consumption,　multichannel　and　easy　extension.　The　experiments　show　that　the　system　can　achieve　multichannel　synchronous　information　acquisition　and　processing,　data　real-time　display　and　storage.　It　provides　an　experimental　platform　which　can　analyze　and　process　data　steadily　and　can　obtain　basic　data　that　nestle　human　motion　state.　©　2013　Springer-Verlag.
