An extension of the ultrasonic sensor is a good supplement to the existing detection system of mobile robots. It has been fully demonstrated in experimental applications, and it has certain practicality in obstacle detection and robot pose adjustment. However, this method needs to be further improve

Analysis of interference factors and measures are takenOne of the biggest disadvantages of using multiple sensors to transmit ultrasonic waves in parallel is that the interference is more serious, especially the signal interference between the sensors. The main factors that cause interference are as

For many years, ultrasonic sensors have been widely used in passenger cars. For example, ultrasonic parking system can help vehicles detect surrounding objects when it is parking at low speeds. In addition, kick-opening the trunk and intrusion detection alarm are two emerging applications of ultraso

Ultrasonic sensors are widely used in robot obstacle avoidance systems. Based on the ultrasonic ranging principle, a parallel ranging system is designed. The hardware composition and software realization method of the system are introduced. Aiming at the phenomenon that multi-sensor parallel ranging

Robot autonomous positioning and navigation of ultrasonic level sensor is simple, but it needs to be based on the combination of map data + algorithm to achieve true automatic automatic navigation; robot navigation can be divided into three parts, including positioning, mapping and motion control. W
