Hi, I try to use wall_follower.py with my real robot, but the terminal show some errors.
[ERROR] [1626273548.479396, 943.979000]: bad callback: <function clbk_laser at 0x7f2f5d2606d0> Traceback (most recent call last): File "/opt/ros/melodic/lib/python2.7/dist-packages/rospy/topics.py", line 750, in _invoke_callback cb(msg) File "./test.py", line 93, in clbk_laser 'front': min(min(msg.ranges[432:575]), inf), ValueError: min() arg is an empty sequence
@ssscassio Could you please help me the problem?
I have no idea how to define the laser region.
I use ydlidar TX20 and angle is 126~-126 degrees, also I reversion it.
