I think the RP Lidar is the best. I think it's called the A1. There's a robot skill in the Navigation category for it. The other popular one is the LGS one, but I believe the quality of the RP is better. But that's just my opinion. :)

Well I bought a LGS awhile back and just hooked it up and nothing. It makes a load clicking sound when spinning, had it too long to send back now, my bad. Ill give the RPLidar a shot.

Thanks for your input.

Check if something's clicking when it spins. maybe a peice of plastic in there? Or the elastic is twisted? or it's rubbing on something. maybe it's fixable
