This paper designs the intelligent robot toy based on Arduino platform.In terms of hardware unit design,the main controller unit,motor drive unit and interactive device hardware selection unit are adopted.By selecting the appropriate Arduino development board,L293D motor drive chip,and various sensors,a stable and efficient in-telligent robot toy hardware system is constructed.In the software module design,voice recognition,Bluetooth com-munication,LCD display,motor drive and other functional modules are arranged.By using STC12C5A60S2 single chip microcomputer as the main control chip,the robot toy has good control and interaction ability.The experimental results show that the intelligent robot toy designed in this paper has good performance in interaction,function,and other aspects,providing children with an intelligent toy that integrates education into entertainment.
