DIY Phone Controlled FPV Rover (Fast & Agile)

Let's build a Bluetooth/ WiFi controlled FPV Drone! RoverBot is a highly educational Arduino based ATV-drone. It's simple to make, easy to program and is a great starter project for hobbyists! The bot is very fast and agile, not to mention of it carrying two "29,000 rpm" motors! It can surely outrun humans regardless of the terrain you're on!

This RoverBot is a soft prototype. My next agenda is to make v2.0 water resistant, shockproof and dirt-proof. The next one would probably carry metal-gearboxes and long range TX RX modules.

How Do You Control It?
RoverBot is based on the famous Arduino development board. Since Arduino supports a wide variety of shields and modules (RC/ WiFi/ Bluetooth), you can choose any type of communication. For my setup, I'm currently using my JY-MCU Bluetooth module, as seen in my previous robot project. You can control RoverBot with your smartphone (via app) and display the FPV footage on another smartphone. Although, Bluetooth has limitations when it comes to range, that's why I'm planning to buy a xBee module to get at least 1km of control.

Endless Possibilities! Ideas!
- Rescue Drone (ex. Redcross Drone)
- Home Surveillance Bot
- Scientific Research Data logging Bot
- Laser Tag FPV Bots!

RoverBot is equipped with:
- 2x Tamiya PlamaDash Motors (29,000rpm - Carbon Brushed)
- Tamiya Twin Gearbox (Configured @58:1 gear ratio)
- Tamiya Track and Wheels Set (With Peg Board)
- 7.4v - 950mAh Turningy LiPo Battery
- Pololu 2x30A Motor Driver
- JY-MCU Bluetooth Module
- 5MP Wireless IP Camera
- Arduino Uno

Building The Bot In 15 Minutes (Fast Forward)

TAKE NOTE: To prevent the brushes from wearing out quickly, the Rover's motor driver is set to half speed (200/400) . Remember, these motors are designed to operate at 3v not 7.4v.

Here are more photo's of RoverBot. Thank you guys for voting! I hope you enjoy the project!

Here's the list of my parts. BTW, wait for a thanksgiving sale in Pololu.com, I saved 55% from their ridiculous discounts.

Attention! Read First Before Purchasing
I bought most of my parts locally, that includes all the Tamiya products and my Arduino Uno clone, the rest were bought online. Please canvas for cheaper prices. Compared to where I buy Tamiya products, Pololu retails Tamiya kits that costs 2x more. If you live in the Philippines then you are lucky enough to have "Lil's Hobby Shop" (located @ SM Megamall & Glorietta 4).

Parts & Matterials (50% Alternatives):
- Arduino UNO R3 Clone
- Pololu Dual VNH5019 Motor Shield (2x30A)
- JY-MCU Bluetooth Module (10-15m Range)
- 2x Tamiya Plasma Dash Motors (Fastest Mini Model)
- Tamiya Twin Motor Gearbox Set (stock motors included)
- Tamiya Universal Plate Set
- Tamiya Track & Wheel Set
- 2 cell 950mAh LiPo Battery
- IP Camera (WiFi Cam)
- Super Glue Bottle
- Sugru Sachet/ Hot Glue

Tools:
- Leatherman
- Screwdriver Set
- Dremel Rotary Tool

Simply upload the sketch to your Arduino. If you have a Pololu VNH5019 Motor Driver, the codes would work like magic! BTW, you'll need to download and install the library in order for the codes to work.
