Hi nice lecture. In unit3, One-dimensional Kalman Filter, the variable Position_from_laser_ray maybe some bug. When i echo it, always some value negative. The kobuki/laser/scan topic from gazebo maybe the source , the ranges all inf.
Yes, I’ve been doing some tests and can confirm that there is a bug with the wall (it’s not being detected by the laser). I have notified this issue to the team so that it gets solved as soon as possible.
