Author:randofo    Randy Sarafan loves you!I am the author of the book '62 Projects to Make with a Dead Computer' and Community Manager here at Instructables. I'm always sharing tons of awesomeprojects. Subscribing to me = fun and excitement!

Intro:  Simple Bots: ScrubAs part of my effort to make our life easier through robotics, I have made a low-cost cleaning bot called Scrub Bot. This state of the art cleaning robot is great at polishingfloors and shining glass tables (provided that you soap it up first). It also disperses small particulates evenly across your floor in such a manner that your home may lookcleaner than it actually is. That's not all! Thanks to its unique non-patented frisbee design, Scrub Bot allows you to easily add all of your favorite thingamajigs and what-nots directly to the bot without wondering where to put them. Create a circuit to toggle each motor independantly for a more "intentionally driven" effect. What are youwaiting for? Make one today! Everyone, but your pets, will thank you.

http://www.instructables.com/id/Simple-Bots-Scrub/

Step 1: Go get stuffYou will need:

(x1) Frisbee(x3) Scrubber brushes(x3) Adjustable tracks(x2) Computer fans (of the same size)(x1) 9V battery connector(x1) 9V battery(x6) 1-1/2" bolts(x18) nuts for 1-1/2" bolts(x6) 1/2" bolts and nuts(x1) a bunch of small zip ties

Step 2: Drill holesDrill holes in the end of each scrubber brush such that you can later bolt on the adjustable track parallel along its length.

You can use the ends of the track as a drilling guide.

http://www.instructables.com/id/Simple-Bots-Scrub/

Step 3: Attach the trackPlace 1-1/2" bolts down through the adjustable track such that the middle slider part is facing upwards.

Insert one or two nuts to space the track off of the scrubber brush in such a way that the middle slider can move freely.

Insert the bolts into the hole on the scrubber brush and fasten it on with another nut.

http://www.instructables.com/id/Simple-Bots-Scrub/

Step 4: Mark for drillingPlace the slider bracket flush with the edge of the frisbee and make marks for drilling.

These marks should be made in such a way that is splits the frisbee into even thirds.

http://www.instructables.com/id/Simple-Bots-Scrub/

Step 5: DrillDrill holes in the frisbee with an 1/8" drill bit.

http://www.instructables.com/id/Simple-Bots-Scrub/

Step 6: FastenFlip the frisbee upside down and tightly fasten the middle sliders to the frisbee using 1/2" nuts and bolts.

The brushes should now be acting to create a tripod to support the frisbee.

http://www.instructables.com/id/Simple-Bots-Scrub/

Step 7: Vibrating motorsTurn your fans into vibrating motors by cutting off some of the fan blades.

You should try to avoid making them evenly symmetrical by cutting off the fan blades in a different pattern on each fan. This will give it a little bit more of a uniquemobility.

http://www.instructables.com/id/Simple-Bots-Scrub/

Step 8: Zip tieZip tie the 9V battery between the two fans such that the fan brackets are facing inwards and the rotors are facing outwards, such that they can spin uninhibited.

Also, you may want to consider connecting them together in such a way that the wiring on each motor, is roughly across from each other.

If done right, the 9V battery should be held firmly in place and the motors should spin freely.

Trim off any excess zip tie bits when you are done.

http://www.instructables.com/id/Simple-Bots-Scrub/

Step 9: Wire it upCut off the motor connectors. Strip back the wire insulation and twist together the red wires from both fans with the red wire from the battery connector. Do likewise withall of the black wires.

You may want to solder them and cover them in electrical tape for a more reliable connection.

http://www.instructables.com/id/Simple-Bots-Scrub/

Step 10: Drill more holesDrill a series of 8 holes such that you can later pass a zip tie through the frisbee and through each corner of the fan motor and then back through the frisbee.

Use your fan assembly as a guide for drilling the holes.

Step 11: Put it all togetherZip tie each corner of the the fan assembly to the frisbee using the holes you drilled in Step 10. Trim off the excess zip ties when you are done.

http://www.instructables.com/id/Simple-Bots-Scrub/

Step 12: Get goingPlug in the battery and you are ready to clean.

Placing the brushes in differing positions creates different patterns of motion.

Try experimenting.

 harkaran says:  Mar 2, 2011. 9:37 PM  REPLYwill dis work faster if i put 4 comp fans instead of 2 ?

 Eman012 says:  Feb 21, 2011. 3:21 AM  REPLYHow long does it take to finish this? And how much the materials?

 rlnbkseeberger says:  Feb 1, 2011. 10:12 PM  REPLYInstead of the bracket/moving things, you could use velcro. Assuming the brushes don't slide on the track when moving. I think that would be cheaper, easierto adjust, and easier to provide symmetry to the movement.

 Eman012 says:  Jan 27, 2011. 1:55 AM  REPLYHow can I make the rotation of the scrub faster?

 dessa_kazune04 says:  Jan 7, 2011. 5:42 AM  REPLYis there another name for the adjustable tracks?or any substitute ?cause i've been to ace hardware and they dont even know what that thing is.it's really hard to find it here in philippines.

 randofo says:  Jan 7, 2011. 10:09 AM  REPLYIt is called an adjustable support. They are use for things like holding up chest lids that pivot upwards or window panes.

It appears to have Ace part #5300421

Here is a photo.

 dessa_kazune04 says:  Jan 11, 2011. 4:36 AM  REPLYthanks a lot!

 cartman117 says:  Jan 8, 2011. 10:36 PM  REPLYWould a pager motor or two work instead of the fans?

 randofo says:  Jan 9, 2011. 9:33 AM  REPLYUnlikely to be powerful enough for something of this size.

 nubabuba says:  Dec 14, 2010. 12:53 PM  REPLYwhat do the tracks help with exactly? i have a school tech fair and i would love to make one of these

 randofo says:  Dec 14, 2010. 6:16 PM  REPLYPositioning the brushes changes its footprint (how it comes into contact with the floor) and by extension, the patterns in which it moves. The frisbee is notperfectly flat, so moving the brushes is actually slightly changing the way it contacts the floor. If you leave them mildly loose on the track to repositionitself, you will start seeing different behaviors emerge.

 nubabuba says:  Dec 18, 2010. 12:33 PM  REPLYok thanks

 nubabuba says:  Dec 14, 2010. 12:55 PM  REPLYwould it work the same if you just glued the brushes to the frisbee?

 2321252 says:  Dec 6, 2010. 1:37 AM  REPLYWHAT SUBSTITUTE WE CAN USE FOR Adjustable tracks

 randofo says:  Dec 6, 2010. 8:50 AM  REPLYYou should be able to find these in the hardware store where they sell window fixtures. If you are in the US, you can definitely get these at AceHardware.

 monleyson says:  Sep 26, 2010. 10:30 PM  REPLYahmmmpppp...........try search another bots can you?I just wanna want your style!!

 ______ says:  Sep 12, 2010. 4:41 PM  REPLYI made your inch worm have the brushes

 dpssouth says:  Sep 4, 2010. 1:44 AM  REPLYcan i use a 12v fan?

 randofo says:  Sep 4, 2010. 11:36 AM  REPLYyes

 saheel says:  Aug 24, 2010. 9:00 AM  REPLYhow much do the fans cost

 dpssouth says:  Sep 4, 2010. 1:26 AM  REPLYi Got them for 2.99

 TANZMEISTER says:  Sep 2, 2010. 4:54 PM  REPLYI rip them outta outdated computers heading to the trash at the university. There are usually 3-5 new computers on the loading dock every week. Eachcomputer has at least one that is super easy to get at, just unclips. And another slightly bigger one inside the power supply. This requires a Phillipsscrewdriver to remove.

 Loosewire; SOE Operative says:  Aug 26, 2010. 9:25 AM  REPLYI found a bunch in a skip outside an office that was updating computers, this time of year there might be some outside schools. Failing that the buy one,probably easier.

 Munchys says:  Aug 25, 2010. 7:49 PM  REPLYGo to newegg.com unless you have a radioshack nearby

 robert0joe says:  Aug 31, 2010. 5:13 AM  REPLYCan I just use the PS2 controller vibrators?

 randofo says:  Aug 31, 2010. 3:15 PM  REPLYI suppose so, with mildly varying results.

http://www.instructables.com/id/Simple-Bots-Scrub/

 rgeddes says:  Aug 28, 2010. 7:28 AM  REPLYI have similar 12v fans I picked up but I find the 9v battery to be underpowered.. I havent put the brushes on yet.. but I feel like there isnt enough of a breezeputting 2 fans on 9v........

 eurofyter966 says:  Aug 23, 2010. 8:12 PM  REPLYAwesome, I like these simple robots you make out of everyday items. " It also disperses small particulates evenly across your floor in such a manner thatyour home may look cleaner than it actually is." That part made me LOL.

 sam10aug says:  Aug 15, 2010. 4:17 AM  REPLYall was good but i could not find the 'adjustable tracks' anywhere.It was really difficult to find it .Even when i get it it,it was quite heavy for the rotation of theentire system.rest of all is just perfect and really saying it is a great plan and looks fabulous while working............But then also find some alternatives of the'adjustable track'.then it would become a great experiment for the aspirant of science to prove themselves in exibition

 blackcorvo says:  Aug 8, 2010. 1:35 PM  REPLYyou could use one of these battery holder boxes, bewteen the fans instead of the battery itself, so you could change for a brand new battery when its dead.http://media.digikey.com/photos/Bulgin%20Photos/BX0023%5EGY.JPG

 khearn says:  Aug 2, 2010. 6:11 PM  REPLYThis looks like it would be pretty hard to change the battery. You'd have to cut the zip ties holding the fans together.

 TANZMEISTER says:  Aug 2, 2010. 1:56 PM  REPLYMy cat thanks you! My wife doesn't.

 agis68 says:  Aug 2, 2010. 3:53 PM  REPLYhahahahaha...I will build it for sure for my cats too!!!.....My wife thank God for the blessed choice supports me everything i do! 

 randofo says:  Aug 2, 2010. 2:21 PM  REPLYOne out of two isn't bad!

 TANZMEISTER says:  Aug 3, 2010. 10:25 PM  REPLYthe wife thought one was pretty cool, but she lost enthusiasm once there were 15 . . .

 0_Nvd_0 says:  Aug 4, 2010. 4:12 AM  REPLYHaha.

 randofo says:  Aug 3, 2010. 11:56 PM  REPLYIs there a picture of this?

 TANZMEISTER says:  Aug 11, 2010. 6:46 AM  REPLYI'm on vacation for a couple of months but I'll do my best to remember to take a picture of them when I get back.

 KarateLover21 says:  Sep 19, 2010. 4:19 AM  REPLYDid post it yet? Where is it?

 koradek says:  Aug 1, 2010. 2:46 PM  REPLYSeems terribly inefficient

 kcls says:  Aug 1, 2010. 11:19 AM  REPLYiRobot isn't going to be happy about this :D Great pics!

http://www.instructables.com/id/Simple-Bots-Scrub/

 ARJOON says:  Aug 1, 2010. 9:31 AM  REPLYincrease its weight and i don't think that this fan would go more efficiently. \ i made one inspired from this project. i used 3 3v small dc motors that is found intoys(made in china. very cheap) removed the motors and connected them in series. i have attacked the metal thing found in electric plugs and it vibtratesvery well. i used 2 9v batteries in papralell and placed all one some cds glued together with the toothbrushes in the back. and all went marvelously. the onlything that is the problem in mine is the noise that it makes.

 yvarcot says:  Aug 1, 2010. 12:18 AM  REPLYDo u have any idea where u get those " Adjustable tracks" as i cant find them aney where thanks a lot

 randofo says:  Aug 1, 2010. 8:49 AM  REPLYAny hardware store. You can find them near where they shelve door hinges. I think they are typically used for windows that swing inwards.

 l8nite says:  Jul 31, 2010. 10:15 PM  REPLYthis is really cool, my 1st thought was to put paint on the brushes and do roboabstracts, its simple enough I may even try it !

 TSC says:  Jul 31, 2010. 4:39 PM  REPLYCool!!!!!

 brunoip says:  Jul 31, 2010. 7:56 AM  REPLYYou take awesome pictures

 Patented says:  Jul 31, 2010. 2:55 PM  REPLYI agree ! To author: Are you using a lightbox or something similar? And I love all of these simple bots, they are awesome !

 dannelle says:  Jul 31, 2010. 11:57 AM  REPLYWOW but it would be much better if it were faster but that would cause more work hehe....

 EmmettO says:  Jul 31, 2010. 10:12 AM  REPLYWould adding weight to this help the scrubbing action? Now if only it could scrub walls . . .
