Self balacing robot using Arduino

[piratebrine]

Great project, I am curious how you managed the dampening in the commands to the servo.

[CrispinProctor69]

@piratebrine I've lost the code but it was quite simple. I had an array[20] of the ADC values for the angle. Sorted it and averaged items 5-15 which did a good job of removing any noise as it would normally fall to the bounds of the array.

[piratebrine]

@CrispinProctor69 What is 'ADC' ?  What was your angle sensor?

[CrispinProctor69]

@piratebrine

I think I used this one: Triple Axis Accelerometer Breakout - ADXL335

ADC = Analogue to Digital Converter. It is internal to the Arduino.

tilt your table, that way much more fun

[tamyboy1]

awesome brotha!

[zacker2000]

will it blend?

[williamthomasmi10]

Rad dude! works reallly well!

[TutorialsByKevin]

COOOOOOOOOL:D

[legomaster12]

Where did u get your servos?? I'm building a similar project

[CrispinProctor69]

@legomaster12

Just got old ones off fleabay. Think I got 12 for about £5. Bargain ;)

You can mod them to rotate continuously. Google is your friend on that one

[unadulterateddagger]

This would be infinitely cooler if those were two AOL install CDs as wheels.

[AWdrius]

Very cool. Nice project!

[Thomas8443]

nice work...

could you please tell me which sensors you are using for this project?

[CrispinProctor69]

@Thomas8443

it was a "Triple Axis Accelerometer Breakout - ADXL335" which just tried to keep it level.

2 CD wheels

[Rubysh88]

U can create a Segway if u make it in a bigger scale xD

[DonQuichotteLiberia]

Nice! Are you using a PI/PID controller?

[TTroboticsROCKZ]

cool

[krustikov1]

wowowowow!

[robodeath]

Does it use an accelerometer?

[dodgedart74]

is there another way?

[LandcruiserClubnet]

sorry folks - I lost all my sketches when a disk failed :(

[tigresno]

@LandcruiserClubnet liar

[guerd87]

Would be very interested to see the code if your willing to release it

[paucarre]

very accurate, good job. Did you use PID controller system? did you have to tune it heavily?

[ThinkIncredible]

nice...cant wait to get my arduino!

[ajp403]

oh shit, thats cool.

[kodabrome]

Import the servos. They cost about US$9 from China, shipped worldwide! :)

[kroutchenu]

try hobbyking online, servo for 1.99$ each...

[jodex96]

I would do a lot of robot projects with my Arduino (it's on it's way from Makershed to me) but servos cost (here) so much! One is about 30€ wich is about 42$... How much in USA?

[jtdreisb]

$27-30 US

[jodex96]

Well it's pretty much too, but better than here =D

[rubstheloationonthes]

there realy cheep if you order them from chinaa on ebay

[amando96]

@jodex96 get them from dealextreme or ebay

[ichguckvids]

That's really cool^^

I'm going to buy me a arduino set and will try to do a simillar robot =D *yeah*

[Flea5000000000]

(: cool

[kom5a]

woow nice!!

[budsiskos]

would you mind posting the code? thanks

[CrispinProctor69]

@budsiskos

Sorry folks, I lost my HDD with all my sketches on. That part that really sucked is the backs were overwritten with corrupt files before the disk went. Lost it all....

[adultricola]

nice work

[VideyoJunkei]

CD wheels are the best!!

[steveboutin]

pretty rad.

[ROYALITARIAN]

NICE WORK

[etniesdc22]

already been done its call a segway

[libed91]

segway is for nerds

[crapkillerz]

plus this is several thousand dollars cheaper...

[sasasasa34]

yeah but it's the fact that he coded and wired everything him self. I want to see you try.

[Soulrider2012]

@etniesdc22 Typical troll is typical.

[kickndave21]

Yeah tell us more about it. Also dude stop complaining about the lighting, lol its about the bot this isnt a fashion show.

[DanFrederiksen]

very nice. I would have prefered a more open place for it and perhaps better lighting and camera work.

very nice stability. looks almost static.

does it suffer form gyro drift over time or can it stand indefinitely?

[etharooni]

That is awesome! How did you measure the angle of the robot? Are you using any gyro or accelerometer module? If so, which one?
