FOBO is the fourth prototype from Project Biped.  It is a 3D printed, self-contained, statically balanced, bipedal robot. It has 8 DOF (degrees of freedom) and can walk around its environment and avoid obstacles using an ultrasonic range sensor.  All of the designs, instructions, source code, and parts lists are provided for free.  FOBO was designed to be easily made by anyone with a low cost 3D printer and an interest in learning about robotics. 

Step 1: Static Walking

FOBO walks statically meaning that at every frame of the animation it is balanced and won't fall over if it stops.  The walking cycle is 10 key frames with 10 frames interpolated in between each frame.
<p>hi I am fast mill 88 aka real name Indy P Doungpanya, I really like how you created fobo he is just so cute and so futureistic and i like to make hover converting things so thanks alot</p>
<p>oh and today feb 22 is my birth day I am 11 now</p>
Help me please
<p>please suggest the proper program or proper arduino coding for servos bcoz i followed all steps u suggested but while compiling its showing error and code is not processing further so please suggest proper and right coding as soon as possible...</p>
<p>Ditch the Arduino bootloader and go C. Our emch engineering student had a golfball collecting robot challenge which I sold some bigger steppers motors to, they didnt need them as after changing to C it was running faster...</p>
<p>how do you use the Arduino without the bootloader?</p>
Yet again wow! your bot looks so professional! It moves so smoothly too. must have been fun getting it to balance with that big box on top!
Thanks! There were lots of face plants while I was working out the walking cycle ... but that was half the fun. Future designs will have the batteries in the feet to help with the weight distribution.
<p>May have a problem with the batteries in the feet as the servos will not be able to work as well as when the weight is higher up and just shifted over the inactive servos. I know because I had the same idea with a robot I built and with the batteries down low, it wouldn't step as well. It's all about leverage.</p>
<p> Heyy) where I can find the code?</p>
<p>Cant you get the static walk cycle to place the balance leg UNDER (ie move it inwards to balance before putting the foot down) the robot rather than use the big lean out angle you have. It would look more natural. I wana build a Reaper from some game I used to play, it needs to 'march' and 'stomp'..</p>
<p>This is a very funny robot, I want to do it</p>
<p>it says :</p><p>This report would have more information with</p><p> &quot;Show verbose output during compilation&quot;</p><p> enabled in File &gt; Preferences.</p><p>Arduino: 1.0.6 (Windows XP), Board: &quot;Arduino Uno&quot;</p><p>Remote_Control.pde: In function 'void SendResponse()':</p><p>Remote_Control:167: error: 'BYTE' was not declared in this scope</p><p>As of Arduino 1.0, the 'BYTE' keyword is no longer supported.</p><p>Please use Serial.write() instead.</p><p>WHAT SHOULD I DO ???????</p>
Hello sir i m from india.I have made this robot bt as i m a beginner so quite unfamilier with arduino programming.I have used arduino and 16 servo controller shield for controlling the robot moments.I have read the navigation program of FOBO and felt some problem in some steps.Sir plzz explain me how FOBO moves forward as written in navigation program of FOBO so that i can modify and write code for my robot.And thnxx sir for sharing this articles.<br>my email adress is anantprasad2222@gmail.com<br>plzz sit help me in programming my robot.I wil be highly thankfull for you sir plzz plzz.
<p>Hello jdowdall, I like it, but it would be nice if you followed what Rohals said about &quot;suggest the proper program or proper arduino coding for servos bcoz i followed all steps u suggested but while compiling its showing error and code is not processing further so please suggest proper and right coding as soon as possible&hellip;&quot;</p><p>I already got really far and spent money to buy the pieces. That would be great if you could provide me with the coding part. Thx.</p>
<p>were can i get the fobo 3d parts to build?</p>
I hope I can build one
<p>good but costly (i mean 300 usd)</p>
nice project. i like it dude
I love this robot i am going to make it
I love this tutorial, Wow :D
Amazing project, where can i find the pieces to make the head and the legs, do u use a 3d printer? :)
Awww, that's one cute little robot! :-)
have you heard of <br>http://letsmakerobots.com/<br>
Thanks for sharing the site. It looks like FOBO would fit in well ... I'll have to make a post there for sure!
Could this be made for those without a 3d printer?
There are websites that will print 3d files for you. I checked out everyone I could find to see how much it would cost for people without a 3D printer to have the plastic parts for FOBO made. The results were ridiculously expensive. The cheapest site was Shapeways which cost around $360 with shipping. That is about a third of the cost of buying a new Thing-O-Matic 3D printer from Makerbot. My advice would be to buy a 3D printer and print the parts yourself rather than pay for someone else to make them. Once you have your own 3D printer it will take about 18 hours to print and consume around 1/5 of a spool of plastic (that's about $10 worth of plastic). If for some reason you don't want to get your own 3D printer I can make the Shapeways FOBO files public so that you can pay them to have it printed ( although it would pain me ;-).
great project!
Oh wow, that's pretty amazing!
Love it, reminds me of the biped walkers in Star Wars ;-)
ATST-- I thought the exact same thing. aka chicken walkers
I knew I wouldn't be the first person who had this as their first thought. Guess that galaxy isn't so far, far away!
It wouldn't be too hard to mod the case either, that would be epic XD
Now that really would be cool!!!<br>I know I'm such a geek :-/
wow It's cool.
Wow that is really cool!<br>
