MobBob V2 - Smart Phone Controlled Robot

[Update 2019-07-14: The app isn't currently available from Google Play. (I need to make an updated version of the app before it can go back into the store.) For now, you can download the most recent version of the APK from here for sideloading to your device: https://www.dropbox.com/s/bncgo25i2rx61jt/MobBob-2016-08-28c.apk?dl=0]

[Update 2015-10-06: The app has been updated on Google Play. It can now connect to most Bluetooth modules. This enables you to use almost any Arduino and Bluetooth boards for your build!]

This is an updated version of my MobBob robot.

MobBob is a smart phone controlled robot. By harnessing the power of your smart phone, MobBob is a walking, talking robot with voice recognition and computer vision that you can build for around $30. I will be continuing to extend his features over time. I want MobBob to be a companion robot that everyone can afford and have fun with.

You can see videos of MobBob in action here:

The main aims of the V2 update were to:

• Support standard 9g servos (previously I was using Arcbotics servos)
• Make everything easier to assemble (no more need for glue)
• Make it easier to adapt/modify for other phones and other batteries. The new bracket system will make it easy to swap in new phone/battery holders. (The provided phone holder STL is sized for a Nexus 5.)

Note that the V2 parts are compatible with V1 parts. So if you are using Arcbotics servos, you can use the V1 legs with the V2 body.

Also, in my V2 build, I'm also using the smaller Bluno Beetle instead of the Bluno Nano, so the entire build is smaller and tidier. :)

MobBob V2 uses the same software as the original MobBob.
