| | | | | I've just started experimenting with mapping and these are my thoughts on it. Drop the robot anywhere in its environment. The robot has a sonar hooked to a servo so the sensor can be scanned horizontally. As the sensor sweeps from left to right, (...) (26 years ago, 15-Dec-98, to lugnet.robotics.handyboard)

| | | | | (...) Watch the critical angle for the sonar too. If the sonar doesn't hit almost straight on, some of the energy will be reflected off at an angle, and may provide false longer distances. Smooth surfaces will have a lower critical angle then coarse (...) (26 years ago, 15-Dec-98, to lugnet.robotics.handyboard)
| | | | | | | | | | | | Re: Mapping —
| | | | | Thanks for the tip on reflection error. I'll have to build in a function to weight the position accordingly. I'm trying to stay away from occupency grids and use the native vectors to conserve memory while maintaining accuracy. I may have to resort (...)
