I have a very small and cheap robot and I wanted to mount a 2D LiDAR on a bottom of it (3cm above the ground). It seems to be great as during the mapping the lidar will detect even small elevations from the ground.
But what happens when a chair will be in front of this LiDAR? I guess it will see only its legs due to a limited optical window (as it is 2D). How can I cope with that? So my robot will not try to go under the chair.
This is the LiDAR: LINK
How can I cope with that?
.... how to cope with what? ..... why would you need to keep the robot from going under the chair? ...... you have not clearly described your project, otherwise these questions would not be necessary $\endgroup$ – jsotola Nov 23 '18 at 0:40
