Background on AR Drone Modification
AR Drones have become popular among enthusiasts who enjoy modifying and enhancing their capabilities. One of the most common modifications involves connecting the drone to an RC transmitter, allowing for more precise control and increased range. In the past, this was achieved by translating the commands from the transmitter through a Wi-Fi connection. However, a new mod called Miru has revolutionized the process, providing a direct and cleaner connection.
The Previous Mod: AR Drone 1.0 to Wi-Fi Transmitter
The previous mod involved using a yellowjacket to establish a Wi-Fi connection between the AR Drone and the RC transmitter. This required soldering and troubleshooting, making it a more complex process. While it worked well at the time, the Miru mod offers a simpler and more efficient solution.
The New and Improved Miru Mod
The Miru mod is a significant improvement over the previous Wi-Fi-Based mod. It plugs directly into the connector on the bottom of the AR Drone and interfaces directly with the RC receiver. This eliminates the need for Wi-Fi, reducing latency and providing a more reliable connection. Additionally, the Miru mod can be easily unplugged, reverting the drone back to its factory state.
Benefits of the Miru Mod
The Miru mod offers several benefits over the previous Wi-Fi-based mod. Firstly, the direct connection between the RC receiver and the drone eliminates latency, ensuring a more responsive control experience. Secondly, the ability to unplug the mod and revert to the factory state provides a cleaner and simpler solution. Finally, the Miru mod is compatible with a range of RC transmitters, allowing users to choose a controller that suits their preferences.
Parts Needed for the Miru Mod
To perform the Miru mod, You will need a few key components. These include an Arduino Pro Mini, a FTDI programming board, a radio transmitter with at least five channels, compatible receivers, servo extension wires, and a cable to interface the AR Drone with the Arduino Pro Mini. The specific parts required may vary depending on the version of the AR Drone you have.
Updating Firmware on the AR Drone
Before proceeding with the mod, it is essential to update the firmware on your AR Drone using the free-flight application. This ensures that your drone has the latest software and is compatible with the Miru mod. The update process can be easily performed through the application's interface.
Programming the Arduino Pro Mini
The Arduino Pro Mini needs to be programmed with the appropriate firmware to enable communication between the RC transmitter and the AR Drone. This involves soldering a header onto the Pro Mini and using an FTDI breakout board to program it. The Arduino application is used for this purpose, with the necessary settings and sketch file provided.
Soldering the Servo Extension Leads
In order to interface the Arduino Pro Mini with the RC receiver, servo extension leads need to be soldered to the appropriate pins on the Pro Mini. This allows for the transmission of signals for throttle, elevator, rudder, gear, and auxiliary control. A Diagram and step-by-step instructions are provided to ensure correct soldering.
Setting Up and Testing the Drone
Once all the components are connected and soldered, and the firmware and Arduino Pro Mini are programmed, it is time to set up and test the modified drone. This involves creating a cable to connect the AR Drone to the Arduino board, using Hyper terminal to monitor the serial output, and configuring the RC transmitter controls.
Overall, the Miru mod provides a more streamlined and efficient solution for connecting an RC transmitter to the AR Drone. With proper firmware updates, programming, and soldering, enthusiasts can enjoy enhanced control and functionality in their drone flights.
