It’s fun to see how different people use the same hardware, and Jan Muller has come up with a really interesting visualisation for his PING range finder. With an Arduino controlling the servo the ultrasonic range finder is swept around the room measuring the distance to the objects around it. The readings at each servo step are transmitted via a serial link to his laptop where a Processing application visualises the angle and distance in a Radar-like screen. Great stuff.

  2. Nice! I’ve done similar, without the processing output, in a simple stop, check 5 directions, turn, proceed simple robot.. I’ve thought of trying to create something that would act like a bat radar, or, using marval comics as a reference, ‘Dare-Devil’ style vision, where it would plot a point on a display, marking how far away the returned signal was. (laying out a digital representation of the contents of the room at the level of the robot with the Ping))).. ) I’ll have to check this one out, it may save me some hair-pulling.

    Cool.. so how do we build it?
