Our team wants to take part in the unmanned boat race, but the commissioning of the boat is difficult. We will use the car to do the experiment first. It can run fully autonomous missions that are defined using mission planning software or pre-recorded by the driver during a manual run. During a manual run, we drived the car to different point, save the waypoint by toggling the auxiliary function switch high (and then return to low). after recording all points, check the mission by connecting with mission planner and then download all waypoints. In misssion plannner,press the “Read WPs” button. To then drive the mission, switch the vehicle into Auto mode.The vehicle can repeat all waypoints exactly. It proves that the here has higher positioning accuracy.
