This research verifies the localization system for a robot walking on rough terrain. The Parallel Tracking and Mapping (PTAM) algorithm and the Inertial Measurement Unit (IMU) are used to determine the 6-DOF pose. The system operates on-line on the real robot. The inclination of the robot's platform is determined by using IMU. The localization system is used together with the RRT-based motion planner which allows to walk autonomously on rough, previously unknown terrain. Efficiency and precision of the proposed solution are demonstrated by experiments.
