This project has evolved some , the basic rundown is I'm modding two Omnibots , one a regular the other a larger 2000 model. I will have two ezb kits , rad base idea was thrown out because of so much noise but could go back on the table if the omnibot drivetrain is too weak to pull it.
Other projects from the same builder.
Robots the community built with Synthiam ARC. Get ideas for your next build.
I think it's too late. I don't understand the above.
mostly for JOSH cif needs more info on how to modify the board for his robot ,can explain it better i guess JOSH would need me at his house
Possibly means that the board wont operate if it cannot sense the motors after removing them? Place a resistor where the motors were connected to fool the health check on startup?
(replaces babel fish and tries again)
I've heard of just using the roomba board all together , h bridge to power the motors and sensors to guide it home to dock. Is this a good idea @robotmaker? Just gut a roomba.
yes thats what i said,it will work perfect,also free up some ports too,it has a built in navigation software MOTORS I GAVE YOU ARE FROM A ROOMBA,they are not the drive motors but vacuum motors with more torque ,but will work great with the board one very small problem using the motors they do use a single optical encoder,so you might need to add them to your design,simple circuit,slotted disc and led and detector,can easy remove them i am working on a better quadrature optical design for roomba ,and made a double battery switching design,one i made for MEL'S roomba turtlebot i sold him
Hey Josh, I have a new board for a roomba if you want it. Never been used.

thats a good ideawill need the sensors and the omnicone on the front panel,front panel has all the sensors,i dont have any extra covers with sensors,all been modify for my ROOMBA TURTLEBOT i am selling ,look up turtlebot on the internet ,its $500 without a laptop,selling mine about $250 with 3 decks,they use the IROBOT CREATE witch is the same as ROOMBA only connections out easy access and no vacuum motors or parts mine also has a second battery design to handle laptop and KINECT sensor on ROS software
This might be a dumb question but which roomba board is it? odel number it came from , I ask because there are a handful of roombas that don't have the docking capability/ feature
