During the month of February, our team gained great process in the white line following algorithm and the PCB IR sensor circuit. I dedicated to researching the shell of our micromouse. In early February, our team had a meeting about the appearance of the shell. Finally, we decided to use blue koopa as the shell’s appearance. I used Solidworks to build this design. In the last week, the model of the shell was almost complete and I had colored it. I still need to measure the micromouse and determine the final size of the shell. I thought that our micromouse could make better progress in the future.
