Omnibot 2000 , Rad 2.0 Vacuum Bot

Skip to comments Jump to end

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.

yes,look for short distance ones like this one should work and digital is better since you are not detecting distance only steps and ledge detection

short distance digital also these are great for non contact bumper switches you set it at 10 cm or distance to hard floor to sensor,then stay high from 10 cm or less like if see carpet or tile or wooden floor,now if you have a step it will be over 10cm and output goes low i dont know what the distance from your bottom of you robot to floor IF can tell me can find you a better one also sensor reads at 24 cm so you need to modify it ,here is the link

short distance digital modify can modify from 10cm to 24 cm ,10cm is 3.94 " and 24cm is 9.449"

another IR sensor will work is 1.5" to 20" but analog ,if you have some ports left over

short distance analog remember to set the distance from robot IR to wooden floor,so it will detect carpets ,floors,and small metal strip for carpets and any thing higher will be cliff detection

and these are great for non contact bumber switches,dont need a bumper guard like on the neato,good reason if using bumper switches robot cant turn around but with non contact IR sensor it can because you can set the distance

on IROBOT ROOMBA is uses them for cliff detection

Ok I.bought 4 of those ir sensors the 4 to 30 cm distance sensors. I may only.use two but spares are nice

Also I descided I could try converting my bot the treads using rover 5 tracks which are 1/8 in thinner than rubber treads on omnibot 2000

Doing.some math I.figured the length.of tracks at max stretch , using omnibot 3 inch wheels its 1.4 inches shorter so the tread should fit snug agianst the hub. Diagrams above show how I would do this. Also on the way is 2 6amp dc to dc converters to reduce drive.voltage , servo supply power and origi nal motors from 12 v

Ok so obviously I'm giving this robot a iron man theme. No better way than for this robot its very own ARC Reactor! I purchased a Hasbro toy but once I recieved it , I noticed it had a unconvincing Amber glow when lit up. I took this guy apart and installed 3 bright white LEDs. It's amazing how much blue color is in a white led. This picture just shows the toy sitting in the placement where I would like it to go. I believe I will cut into the speaker location a recess the ARC reactor in about 1/2 inch deep or more. Once it has been installed into this torso it will also be painted the same crystal red color. If anyone has additional ideas let me know.
