I'm thinking about a new project.
For this project, the robot must know the distance to all the walls around him.
To do this, I thought about building some kind of a radar, which rotates a distance sensor, measuring the distances in all directions.
Which sensor should I use? I think that ultrasonic sensor has too wide angle for this assignment. Is it correct?
If someone has a better idea for this mission, I'll be glad to hear.
While trying to detect walls, It should do great.
Once I'll try to sample the distance in a corner, it won't be very precise, as it would read the distances of the walls of that corner instead.
Inaccuracy will be a problem also near objects, as seen in the attached picture.
I might be wrong, I'm not an expert.
Please correct me if I do
i think most of those robots just drive forward and once they hit something they change direction.if you then let him like drive around for a couple of hours and save the movement data you could maybe create a map and a grid of the roomsize so that the robot might find a much faster and better way to clean up the all the next times, afterall he needs to know where he has cleaned up already.
