I've finally mounted the awesome Open Source Laser Range Finder (OSLRF01) onto Bottwo with a panning servo to provide mapping functionality.
I was previously attempting to do this with the Sonar, but was stymied by limited range and cone size.
The narrow beam and greater sensing distance of the LIDAR will give me the ability to accurately map out a room in near real time, and then use the other sensors for closer proximity measurements.
How much is too much?
Yeah, I heard that! Yes, I've got four Sharp IR Sensors, two front and back for collision detection, two left and right for following walls at a specific distance.
I've now got two more short range IR sensors front and back facing the floor... so we don't fall down stairs again.
I hope to have video up soon of this in action.
