Abstract 　A dist ributed mult ip le senso r system w ith open arch itecture is p resented. The imp lementat ion of moudules fo r vision input and output and ult rasonic ranging is int roduced. Modules w ith m icrocont ro llers in the system p rocess their signals parallelly, and communicate w ith ho st p rocesso r by dual po rt memo ry. The designed vision input and output module has th ree input channels fo r analog vision signals and one analog output channel. The ult rasonic ranging module can p rocess 16 input signals simultaneously. The developed system has been suc2 cessfully app lied to experimental researches of mobile autonomous robo t s.
