Design and Development of Modular Detachable Educational Robot Based on Scratch

A plug-in multi module Arduino educational robot based on USB is designed from the perspectives of software and hardware. The software part is based on Mixly and adopts graphical programming. At the same time, the hardware part is divided into several circuits based on Altium designer, and then converted into the final PCB diagram. Through welding, debugging, burning bootlocked and other operations, finally, combining software and hardware, an Arduino chip operating with USB port is designed and used in the intelligent obstacle avoidance car. The running results show that the developed USB pluggable Arduino educational robot has certain teaching value
