HI RichMR2

Seems to me your robot only has to do a bit of wall following to find the door at the bottom of your stairs. Dont matter which way it goes it will find the door , Then it will see the charger beacon.

Beats spending a lot of $ just to find the beacon.

DOOR f is very hard to go through also ,when you have about 12 inch round or square robot and still hard for a smaller one too ,i guess RICH will be using many QR codes all over his house and may be others too

yes that is what i said ,I CANT POST IT,

But ii am using the EZB to do the same thing wiith my automatic charging base and homebase finder so yes i CAN post it here

ROBOTCHAT can be 2 EZB together one on the home base and the other on a robot and using scripts it almost talks to each other

I think we all know very well RICH we cant post any software unless it uses EZB in the design,since this forum is about EZB and builder,NOW on adding the software to EZB you will need to use ARC SDK

I only posted my design that works with my software to CONVERT IT to EZB and using 2 EZB to talk to each other control the sensor for navigating to home base) i have part of it working

Automatic charging design and home base finder project ,i have working on the design for a few years

I look at and build other designs by others ,and added a few to my designs also. that why this is a major topic for me ,because i know a lot about it

Also look at wireless battery charger designs,some use SONAR to charge a battery ,and some using to coils to transfer the battery charge current to the battery by wireless one is to place a coil inside a robot and circuit to change AC inductance to DC current and another on the floor with another coil to transfer the AC inductance to the robot coil.

it does work fairly well,need to make design a little better,by making my own coils it works like a transfomer ,but without the iron core

@robotmaker, it goes through the door just fine, it's never got confused there. Also re-read things, I have not said I will be using QR codes. I said that it can be done with QR codes. This discussion is about the methods available in general. If it was about my specific project then I would be posting it in that topic. As this is a community forum I try to push ideas to become more generic than specific.

do you know that for a fact ,have you built a design and had to go though a door

YES it can been done with QR codes,not the best solution,since you havent tested it first.plus has a few problems like cant see QR codes behind a wall or if the robot is facing the other direction.

BUT with sensors ,mapping and 2 EZB together letting the robot how to navigate to the room he is in is the best way.

THIS I HAVE TESTED,but not with EZB but with 2 other CPU's and software and should work the same as EZB if not may better.

So until you test the design perfect cant really say it may or maynot work

i do have a lot of projects and i am hopping to put this my home base design up soon,my main project is my johnny five project first,need to finish it before the next SHORT CIRCUIT comes out

Re-read my posts, I have covered the QR codes more than once yet you fail to acknowledge the solutions to your problems

And yes, I have tested my robot going through the door. My robot will avoid all furniture in my house and roam freely around the entire ground floor of my house without a problem (other than disconnection when it get's too far in to the kitchen when running ARC on my HTPC). If I hadn't tried it I wouldn't have been able to say it's never got confused going through that door.

I have also tested the range that my robot can detect and read QR codes and explained solutions to QR codes which may be behind the robot, too far away or in another room.

please you dont need to yell,i read you posts very well Witch robot,does that you are still building one last time,also what size is your robot if its a small one then its easy.

and yes my solution does 100 % percent work ,it seems everytime i bring up a idea that i am very good at,you knock me down every time on every post

please post your design and scripts if you say it works

I cant yet .i need to finish my EZB design,but the disegn does work and tested on another microcontroller design so by porting it to EZB it will work the same . mine go though dors fine too also post a video it shouldnt be hard for you to do

IF you have a design that you said work and you SAY you are not using it,how can you say you tested it and place QR codes on the wall,QR codes does work if placing a card in front of it.may be thats you test,but you need to have a design and have QR codes on the wall with the scripts to control it ,or its not a test

very strange that the camera cant see behind the robot it only has 180 deg pan ,yet you say you can detect the QR codes and i love to see a camera see though walls to see the other QR codes,i guess you have a x-ray CAMERA i guess
