The description of MobBob

This app was designed for use with MobBob, the 3D printed robotic companion!

(Note: You can try this app even if you haven't built your MobBob yet. If you use the "Don't Connect" button, you can play with the voice recognition and computer vision features before you build MobBob.)

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.

To share my love of robotics and to encourage people to build robots, I'm making available all the files needed to build your own MobBob - the 3D printable files, the Arduino code, and this app! You can find links to these below and on my website http://www.cevinius.com.

If you get stuck, you can ask me questions at my website!

If you hunt around and wait for discounts, you should be able to buy all the parts needed for around USD $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:

MobBob's body is 3D printed! You can download the files to print them from Thingiverse:

I'll be adding some 3D printable MobBob accessories there soon! So stay tuned.

MobBob's body is controlled by an Arduino compatible board (the Bluno Beetle made by DFRobot). The code for the Bluno can be found here:

The app connects to DFRobot's Bluno boards using the Bluno's built-in Bluetooth LE.

The app can now also connect to many other Bluetooth boards using regular Bluetooth. You can see a demonstration of this functionality here: https://www.youtube.com/watch?v=Ykxdeoo8vkQ

MobBob is not too hard to assemble and there are photos and notes about that on the Thingiverse page. However, I'll soon be posting some detailed assembly, wiring, programming instructions on my website:

Check out the videos for demonstrations of MobBob's current functionality and how to use the app! :D

This will be expanded soon, but he currently understands voice commands (in "Companion" mode) that contain the following key phrases:
"go forward"
"go backwards"
“go left"
“turn left"
“go right"
“turn right"
“how are you"
“favorite person"

I will be adding more commands like I did with my Sphero Companion app.

I hope you have fun with my little robot! Please send me a message or post a picture of your MobBob if you build him. I would love to see his relatives. :D

MobBob 2.02 Update

Improved connection UI panels.

This update adds new connection options:
- Connect using regular Bluetooth (paired device)
- Connect to DFRobot's Bluno using Bluetooth LE (no pairing required)
- (Experimental) Connect to HM-10 using Bluetooth LE (no pairing required)

These new connection options provide a lot of flexibility for building your MobBob. You no longer have to use a DFRobot Bluno board. You can now select other Arduino/Bluetooth boards for your MobBob.
