Smart Phone Controlled Robot - MobBob V2 Remix Upgrade
3D Design Tool: SketchUp Pro
Design concept: RAPIRO - The Humanoid Robot and Gundam
This is an remix upgrade 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 [base version]. 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 V2 Remix upgrade in action here:
The main aims of the V2 remix were to:
Support standard 9g servos [previously I was using Tower Pro SG90 servos]
Make everything easier to assemble [no more need for glue]
Make it easier to adapt/modify for other phones. The new bracket system made it easier to exchange a new phone / the battery holder.
Also, in my V2 Remix build, I'm also using the Arduino Nano instead of the DIY Nano shield, so the entire build is smaller and tidier. :)
MobBob V2 Remix uses the same software as the original MobBob V2.
You can find the latest Arduino code here: https://github.com/cevinius/MobBob
The modified code is included: http://www.thingiverse.com/thing:1232619
You can download the latest version of the Android app from Google Play - it is free, ad-free, and without IAP:
You can find more detailed build and wiring instructions here:

This is a small, Arduino compatible ATmega328 board with DIY extension board. MobBob V2 app connects to the Bluetooth module using its Bluetooth LE service. The app to support other Bluetooth cards.
You can use other batteries that provide 5V with a steady current. If you use other batteries, you may need to adapt the battery rack for your battery's size.
Use 18650 Lithium Battery Charging Board With Protection Charger Module and Step Up Boost Module 3.7V to 5V for Smart Phone
You can use other Android Smart Phones with This app.
You do not need to adapt the size of the phone holder for your phone. The app has been successfully tested with Nexus and Samsung, LG phones, but should work on other Android phones.
Print all the required parts
Get all the non-3D printed parts
Assemble as per the photos - I'll be writing some more detailed instructions on my website soon!
Install the Arduino code from the GitHub link in the description - You will need to update the Arduino pins in the code to match yours, and probably update the centering values for the servos.
Install the Android app from the link in the description.
If you hit any problems, please post a question on this website: [http://www.cevinius.com], here, or on YouTube channel. A few people have built MobBobs now, so there are people around who can help.
Coming soon update!!

Thanks for the advice, I was just thinking about the question of whether it is possible to make a card for cryptocurrency payments, now I know where to find the answer to my questions.
Hello, if you want to choose a card to make payments immediately in cryptocurrency then you should try to address this question on the Revain Review platform and read reviews about the maps that interest you here https://revain.org/crypto-cards You can completely trust the reviews on this platform, because Revain is a feedback platform based on blockchain technology that stores information about the company and reviews about it.
