The　inspection　robot　is　an　industrial-specific　robot.　It　can　realize　a　variety　of　sensor　information　fusion,　multiple　communication　methods,　multiple　intelligent　control　methods　coexist,　and　can　be　autonomous　navigation　and　positioning.　with　broadly　application　foreground.　In　this　paper,　the　structural　design　of　the　wheeled　detection　robot　is　proposed,　and　the　wheel　drive　system　of　the　wheel　detection　robot　based　on　STM32F405　and　DRV8302　is　designed.　A　set　of　brushless　DC　motor　servo　system　with　speed,　current　and　position　three　closed-loop　structure　was　designed　for　testing.　This　paper　mainly　introduces　the　hardware　design　of　the　robot　chassis　drive　system.　And　the　experiment　shows　that　the　hardware　design　can　well　meet　the　actual　operation　needs　of　the　inspection　robot.　©　2019　IEEE.
