Description of shortcomings of traditional rescue vehicle

The advantage of a single wheel is that by adjusting the angle and speed of the two steering wheels, the car can change lanes and turn without turning the front of the car. The advantage of two wheels is that they can turn along any radius point, which is very flexible. The disadvantage of single wheel is that two sets of steering wheels are added, and AGV often needs two steering wheels for differential when maneuvering. The disadvantage of two wheels is that their two wheels require higher motor and control accuracy, and the progress increases the development difficulty and cost.
