Eddie the Balance Bot

Feb 23, 2015 - Eddie has been upgraded to EddiePlus and he's even better now. Please visit him at [www.thingiverse.com/thing:694969](http://www.thingiverse.com/thing:694969). Hi everyone! This is Eddie. I'm a tiny self-balancing robot that was inspired by SparkFun Electronics for making really cool building blocks and Intel for making the Edison. From SparkFun, I used the Edison Battery Block to power me. The 9DOF Block for inertial measurements. A Base Block for terminal access and the OTG port for the USB camera. And finally the Dual H-bridge Block for controlling my two motors. My motors and wheels came from Pololu. I went with 200 rpm high-power micro metal gearmotors and 60mm wheels on this first build. More build details can be found in the instructions tab at [www.thingiverse.com/thing:655423/#instructions](http://www.thingiverse.com/thing:655423/#instructions). With my 400mAh battery, USB camera streaming video, my run time is about 1 hour and 15 minutes. I can be remote controlled via WiFi. My programming is under development and source code is available on GitHub at [github.com/r3n33/EddieBalance](https://github.com/r3n33/EddieBalance). Demo video: [www.youtube.com/watch?v=XQCCbod4Lm4](http://youtu.be/XQCCbod4Lm4) Remote control test video: [www.youtube.com/watch?v=i16xHtEtRII](http://youtu.be/i16xHtEtRII) Instructions Print two motor brackets and one of each of the remaining files. The tray was just something basic and is totally optional. My arms are attached with M3 screws. My motor mounts and the Edison blocks use M2 screws. I'm currently waiting for a shipment of M2 screws, standoffs, nuts so how to attach the boards will be up to you for now.

There are still a few left at [www.ebay.com/itm/310599343436](http://www.ebay.com/itm/310599343436). And the first and only software I've tested with the camera (so far): [github.com/drejkim/edi-cam](https://github.com/drejkim/edi-cam).
