I am working on a ROSBOT for a natural navigation project.
While working with RpLIDAR A2 version, I found that it does not sense thin black surfaces like black pants/trousers while at close range (less than 30 cms).
The screenshots of the RVIZ visualization of the robot is attached below
When the person at more than 80 cm from the LIDAR
When the person at more than 50 cm from the LIDAR
When the person reaches 30 cm from the LIDAR
I tried debugging the code, but no errors in the code.
What are the methods we can use to improve sensing of the robot, can we do any hardware or software tuning to the RpLIDAR sensor to improve its sensing?
What are the likely errors causing this behaviour?
