After years of testing and iteration, the MIT ROBOAT autopilot ship, which was established in 2016, has been upgraded to accommodate two people at the same time. In addition, thanks to the improvement of sensors and environmental information monitoring system, the latest ROBOAT II can also intelligently judge waterway, cooperate and transport passengers and goods. It is reported that the length of the early models was only 3.3 feet (1 meter), and the proportion was only 1 / 4 (4 meters / 13.1 feet) of the final product. < / P > < p > it is worth mentioning that ROBOAT II uses a novel synchronous positioning and mapping (SLAM) algorithm to help ships plan the best route to their destination. Of course, lidar, GPS and inertial measurement unit (IMU) help along the way. < / P > < p > the research team envisions a network appointment travel service based on waterway, similar to Uber. When a passenger requests, the system can arrange the nearest ROBOAT II to reply, and then use SLAM algorithm to arrive at the destination. < / P > < p > during the test, the research team put the robot II on the canal in Amsterdam and carried out a three hour round trip, with the measured error controlled within 17 cm (6.7 inches). < p > < p > Wei Wang, one of the researchers, pointed out that in order to develop an autonomous waterway transportation system that can accurately map and stably control, the robot II The first step is their full-scale deployment.
