In addition, the working environment continues to deteriorate due to global warming, and electric carts are being developed to solve this problem.

그러나, 특히 농작물 사이로 이송을 용이하게 하기 위해 외륜 전동 손수레가 많이 사용되고 있는데, 하나의 바퀴로 구동되는 외륜이므로 방향 조작이 어려우며 또한 균형을 유지하기가 어려운 문제점이 있다.However, in particular, a paddle-wheeled electric cart is widely used to facilitate transport between crops. However, since the paddle wheel is driven by one wheel, it is difficult to control the direction and maintain the balance.
