Trying to reach new heights with the AR.Drone out in a field. It does go quite high for a toy quadricopter if you ask me. Flight was reasonably stable but the controls were not very responsive.
The video was shot with Display Recorder, but at the end a lot of frames have been skipped. This video had the following settings: Rotation: Landscape Left, Video Quality: Medium, OpenGL capture: On, Grayscale: Off (obvious), Framerate: 20fps and Lock Framerate: On. I will try to play with the settings and see whether I can improve the quality of the next video. If you have better quality please leave your settings in the comments. Perhaps the lack of responsiveness of the controls is related to Display Recorder.
A GoPro HD Hero camera to the top of an AR.Drone and shot the following video. The GoPro camera lets you record up to 9 hours of video to an SD-card in HD quality. You won’t get that quality with the built-in cameras.
[Unfortunately the video on Vimeo was set to private]
Unfortunately it was already dark yesterday when I wrote my previous blog post about how you can use Display Recorder to record the AR.Drone video streams from the onboard cameras. So I had to wait to shoot a demo video. But without further ado I present you the recording of my first emergency landing. (And yes I know, you probably should not fly near those overhead electricity conductors and pylons).
One of the features that is missing from the FreeFlight software is the ability to take pictures or record the video stream from one of the two onboard cameras. This drone thing was supposed to bring Big Brother surveillance capabilities to the masses, wasn’t it? The video stream for the front and bottom camera is displayed on the iPhone screen but there is no way you can record it. Not unless you jailbreak your iPhone and install Display Recorder by Ryan Petrich ($4.99 in the Cydia store).
With Display Recorder installed you can record everything that is displayed on your iPhone screen. Once installed you start it by pressing the sleep button for 1 second. Display Record will ask you if you want to start recording. It will then record everything to an AVI-file until you press the sleep button again. After recording you can upload the video directly to YouTube from your phone or download the files to your computer through a integrated webserver that you can turn on in Display Recorder.
If you want to record the video from the cameras on the AR.Drone you will have to change Rotation to Landscape Left or Landscape Right in the Display Recorder setting. Display Recorder settings can be found as an option in Settings on your iOS device. Other things you probably want to change are to not Show Taps and perhaps use a higher Video Quality.
One of the first things you get annoyed by once you fly your Parrot AR Drone is the short flight time. Before you know it the battery runs out and you have to hook it up again. You can order some spare batteries from Parrot, but if you feel a little bit more adventurous you can order a battery from another brand with a higher capacity. The standard battery that comes with the AR Drone is only 1000mAh. According to the specifications this allows for 12-15 minutes of flight. Charging this battery takes some 90 minutes.
The 1300mAh battery used in the following video adds approximately 4 minutes to your flight time, but your mileage may vary. The video has a walk-through of how you can modify a custom battery if the connectors do not match.
Amazon sells the Parkzone 11.1V 1300mAh Li-Po Battery with EC3 Connector that is featured in the video for $32.
