+* `HAL.getPose3d().yaw` - to get the orientation of the robot with regarding the map  
 * `GUI.showImage()` - allows you to view a debug image or with relevant information
 * `GUI.showParticles(particles)` - shows the particles on the map. It is necessary to pass a list of particles as an argument. Each particle must be a list with [positionx, positiony, angle].    
-* `GUI.showPose3D(pose)` - shows the estimated position in the 3D viewer. It is necessary to pass a list with [positionx, positiony, positionz]. The 3D viewer will also show the real position of the robot, so you can compare how good your algorithm is.
