This SainSmart 4WD Drive Mobile Robot Platform for Robot Arduino UNO MEGA2560 R3 Duemilanove can hold many controllers, drivers, sensors and RF modules etc. Ultrasonic sensor HC-SR04 is used here to measure distance in range of 2cm-400cm with accuracy of 3mm. Ultrasonic sensor is one of the most popular external sensor among various external sensors for mobile robots. The URM06 - UART Ultrasonic sensor provides very short to long-range detection and ranging from 20cm ~ 10m, comes in a compact, robust PVC housing and matches 35mm electrical pipe mounting. Kim et all, Obstacle Avoidance of a Mobile Robot Using Vision System and Ultrasonic Sensor, Advanced Intelligent Computing Theories and Applications. Based on product, the sensor for mobile robots market is segmented into resistive sensors, tactile sensors, infrared sensors, ultrasonic sensors, encoders, inertial sensors, and external sensors. A further caveat is that a short robot may end up with very limited range before the sonar sensors detects the ground below the bot. obstacle avoiding robot using ultrasonic mobile robot localization are hampered by many uncertainties. Ultrasonic Sensor based Luggage Follower 47. I've been struggling for some time on this
