硬件API
使用NI 9401 C系列數(shù)字I/O模塊,，小組利用編碼器來(lái)測(cè)量速度和位置,。通過(guò)與硬件的緊密結(jié)合，他們可以快速的從多個(gè)傳感器中獲得數(shù)據(jù),。
為了確定機(jī)器人的狀態(tài),，該小組采用了數(shù)學(xué)函數(shù)進(jìn)行卡爾曼濾波。他們利用了LabVIEW 內(nèi)置的數(shù)學(xué)函數(shù),，對(duì)傳感器測(cè)量的數(shù)據(jù)進(jìn)行了內(nèi)聯(lián)分析,。
為了檢測(cè)到障礙物，學(xué)生利用NI視覺(jué)軟件進(jìn)行采集,，處理并顯示來(lái)自攝像頭的圖像,。利用用戶界面，學(xué)生通過(guò)色彩和視覺(jué)紋理來(lái)識(shí)別障礙。
機(jī)器人采用嵌入式實(shí)時(shí)處理器和現(xiàn)場(chǎng)可編程門陣列（FPGA）實(shí)現(xiàn)高級(jí)控制,。模塊化I/O系統(tǒng)與傳感器和制動(dòng)器連接,，來(lái)進(jìn)行實(shí)時(shí)圖像處理。
學(xué)生利用FPGA技術(shù)的優(yōu)點(diǎn)來(lái)采集時(shí)序要求嚴(yán)格的數(shù)據(jù),，以控制機(jī)器人,。與VHDL相比，LabVIEW 圖形化編程簡(jiǎn)化了嵌入式FPGA程序編程的復(fù)雜性,。
為了整合現(xiàn)有的代碼,，學(xué)生采用了調(diào)用庫(kù)函數(shù)節(jié)點(diǎn)，將ANSI C中開(kāi)發(fā)的算法合并到LabVIEW程序中,。結(jié)合LabVIEW中的多種編程方式,，學(xué)生實(shí)現(xiàn)了代碼重用和開(kāi)發(fā)優(yōu)化。
