This is an idea I have for some time and I would like a little squeeze.
A navigation system for corridors but also for the house in general.
This is placing two ping sensors, one on the left and one on the right of the robot (on the sides) and take readings almost simultaneous.
Then make a script that allows measurements equate the two so that Correct the robot path and always flows through the center of the hall.
Let's say this is the beginning of the theory and that the Scale system is called ultrasonic, if this is handled by a script, and can be combined with other scripts, the way " Scale electronic" can be interrupted when the corridor forces you to turn the right for example, the sensor readings and not make a total of 30 inches (15 per side) for example, but 15 inch mark on the left and on the right 40, which sum 55 inches, very different 30 inches of aisle.
This would be a way for the robot to make a decision, locate the end of the hallway or even distinguish the different rooms running through their center and measuring the total distance side.
Data could also be used as light or room acoustics combined with ultrasound report distances to obtain a more reliable without being infallible report, I think it would be enough with a 93% chance of success.
Ezb can.do.2d floor map , at that point the robot only needs a method of seeing.where it is on.this map and ofcourse avoiding obstacles along the way. I can imagine with a complicated enough environment that each rooms map and object.placements are unique. Once a robot has a 2d map it's reasonable to say if it had a distance sensor on every side and radar to.avoid obstacles that there is a way to take those 4 measurements and the robot calculate where it is on the map with a few inches accuracy.
I use to work for.Dupont textiles and they had a robotic packing arm and about 50 car sized robots that would retrieve bobbins from one end of plant and bring them to pacman (that's our nickname) the robots bringing.bobbins.received a.wifi signal to let them know which dolfing room to pickup bobbins.from and the robot.used.precise encoders and a spinning 360 degree laser rangefinder to measure the hallway and surround area about 3 times per second. It also.has front and rear.ultrasonic sensors to aid in positioning so it didn't hit another robot and equipment or even people that may be below.it's main 360 degree eye.
JOSH same type of robot they had in a hospital i was in for a few days,i saw a robot with few sonars and sensors and a laser spinning 360 deg(LIDAR) and they would go ropmm to room bringing stuff i was told i could visit the room that where they progra m them ,but havent had a chance ,its at another hospital,LASER is best navigation tool here is one item needed is encoders and DJ said he is working on it i have 12 of the lasers i am getting ready to sell ,with control board with software here is a link to the LIDAR
NEATO LIDAR HACK
also most lasers are $1000 and up and most robot builders dont have that much cash ,so the one from NEATO XV-11 vacuum cleaner is near $150 and if you check the specs the accuracy is about the same ,,so its a great navigation sensor at a very low cost
