MobBob V2 Remix Upgrade - Smart Phone Controlled Robot

youmagine

This appears to be a 3D printing project design for an Android-controlled robot, MobBob, using Arduino and Bluetooth technology. Here's a breakdown of the provided information: **Components** The project requires several components, including: 1. CC2540/CC2541 Serial Wireless Module 2. 5V Micro USB 1A Lithium Battery Charging Board 3. DC-DC Converter Step Up Boost Module (2-5V to 5V, 1.2A) 4. Rectangle On/Off Long Rocker Switch SPST 5. Snap-In Single 'A'-'AA' Battery Contacts (2x) 6. 18650 Lithium ion Batteries (2x) 7. USB Cable (300mm) 8. Smartphone (any Android device) **Non-3D Printed Parts** The following non-3D printed parts are required: 1. Arduino Nano 2. Bluetooth Module 3. Battery Extender (optional) **Instructions** To assemble the project, follow these steps: 1. Print all required 3D printed parts. 2. Assemble the components as per the photos provided. 3. Install the Arduino code from the GitHub link in the description. Update the Arduino pins and centering values for the servos if necessary. 4. Install the Android app from the link in the description. 5. Have fun! **Notes** * The project uses a DIY extension board with an ATmega328 microcontroller (Arduino Nano). * The battery extender is optional, but can be used to power the device using other batteries that provide 5V with a steady current. * The smartphone holder is designed for Android devices and does not require any adaptation for different phone sizes. **Print Settings** The project uses a PANDORA DXs DIY 3D printer with Cura 15.04.2 as the slicer software. The print settings are: * Layer height: 0.1mm * Shell thickness: 0.8mm * Bottom/Top thickness: 1.2mm * Fill Density: 00% * Print speed: 50mm/s * Print temperature: 200°C * Bed temperature: 70°C **Additional Resources** The project author provides additional resources, including: * A YouTube channel for questions and support. * A website (http://www.cevinius.com) for more detailed instructions and updates. Overall, this appears to be a fun and challenging project for those interested in robotics, Arduino, and 3D printing.
