Opis:: In this paper, a method for calibrating the sensory system of a walking robot is proposed. The robot is equipped with two exteroceptive sensors: a 2D laser scanner and a stereo camera. When using the CAD model of the robot, the positions of both sensors defined in the robot's body reference frame can only be determined with limited precision. Our goal is to create a method which allows the robot to find the position of the mounted sensors without the need for human input. The presented results show that the method is not only fast but also more precise than calibration using the CAD model.

Opis:: This paper deals with problems of rough terrain perception and mapping for walking robots equipped with inexpensive optical range sensors providing 2D data only. Two different sensing modalities are considered: the structured light sensor, and the Hokuyo URG-04LX laser scanner. Measurement uncertainty in both sensors is taken into account, and different geometric configurations of these sensors on the walking robot are analysed, yielding the configurations that are best for the task of terrain perception. Then, application of the acquired range data in local terrain mapping is presented. The mapping algorithm as well as novel methods for removing map artifacts that result from qualitative errors in range measurements are detailed. Experimental results are provided.

Opis:: This article considers selected operational characteristics and measurement errors of the 2D laser scanner URG-04LX, which is a compact sensor suitable for walking robots. Quantitative errors in range measurement are evaluated considering the intensity output available from the sensor. The obtained intensity values help to correct the range measurements with regard to the optical characteristics of the observed surfaces. Moreover, mixed measurements are characterized and compared to the mixed measurements characteristics in the popular Sick LMS 200 laser scanner. Finally, it is shown how taking into account the error characteristics of the URG-04LX scanner improves its performance as the main exteroceptive sensor of a small walking robot.
