Hello,

this is position of my simulated robot.

How you can see right side of the robot is near the wall but left not. After rostopic echo /scan i have similar value (around 1.3) on ranges[0] and ranges[719] what does’t make sence. Is there something wrong with laser or what that mean ?

That’s because ranges[0] corresponds to the back of the robot (the front is the middle value), so ranges[719] would be very similar.
