Implementing rover speed control in Paparazzi UAV

Abstract

[Abstract] This paper presents the design, implementation and testing of a speed controller for an autonomous rover with an unicycle drive. The aim is to get the rover to follow the speed setpoint as accurately as possible based on low cost GPS measurements. The use of IMU and GPS measurements was investigated and a moving average filter was designed to use the GPS signal as feedback for the speed controller. This filter and speed control were implemented on a flight controller board on a small autonomous rover using the the Paparazzi UAV development framework. Outdoor tests were performed.
