개요1. 준비물 소개2. 구성도3. 제작 과정4. Drive 코드5. Camera 동작법6. 실제 동작모습 1. 준비물 2. 구성도 3. 제작과정테스트하는데 와이프가 시끄럽다고 잔소리 들었음ㅠ그래서 조용조용 만듬~ 원래 Servo 모터로 카메라 회전까지 하려 했으나Servo 모터에서 테이프가 자꾸 떨어져서 포기~ㅋ붙이다가 짜증났음~ㅠ 4. Drive 코드a 입력하고 Enter 치면 좌회전, d 입력하고 enter 치면 우회전Command 식인데 게임하듯이 만들면 됨그래서 찾은게 python에 pygame 이라고 게임 만들때 쓰는 라이브러리 인데지금은 일단 패스코드는 첨부파일에 존재함 5.
