Robots also require navigation hardware and software in order to anticipate on their environment. In particular unforeseen events (eg people and other obstacles that are not stationary) can cause problems or collisions. Some highly advanced robots as ASIMO, EveR-1, Meinü robot have particular good robot navigation hardware and software. Also, self-controlled car, Ernst Dickmanns' driverless car and the entries in the DARPA Grand Challenge are capable of sensing the environment well and make navigation decisions based on this information. Most of the robots include regular a GPS navigation device with waypoints, along with radar, sometimes combined with other sensor data such as LIDAR, video cameras, and inertial guidance systems for better navigation in between waypoints.
