Autonomous mobile platform II

The paper presents design of autonomous mobile platform based on the all terrain 1/8th scale four wheel drive radio control model. In this paper was considered problem of automatic control of mobile platform using information from GPS system, electronic compass and encoder. The mobile platform is equipped in two-stroke glow engine, heavy-duty drive train and wide-track suspension and controller based on ARM7 microcontroller and using MaxStream XBee Pro 2.4GHz radio modem communication module. The base station equipment is also described. Communication protocol between mobile platform and base station is presented. The paper presents also an application of electronic compass to measure azimuth of mobile platform. Problem of speed and distance control is described. Autonomous mobile platform is a machine that can operate in a human-made environment. By control in this case we will understand to be able to avoid collisions with obstacles (other mobile platforms and walls) during drive. Results of real application are also shown. Results of work on autonomous mobile platform that can operate in human environment are presented. The obtained properties of the system have been effected that it can be used for future research and autopilot design project.
