Disadvantages: the price cost is high (generally, the normal price is 50000-80000, and the machine of 120000 has been seen).
Gyroscope+ultrasonic+motor feedback (trackless navigation) Advantages: The combination of various technologies saves the expensive laser sensor, and the price is close to the people (Tianjin Tian Qiang Science and Technology seems to have the price of 30,000+,and it seems to have automatic charging and two-way welcome function, which can directly Baidu? Disadvantages: It cannot be used in places with extremely uneven roads. There is nothing wrong with the general tile floor.
