One of the more important features that will arrive with Copter-3.4 (still in beta testing) is the Polygon Fence (the full list of features can be seen in the …Continue
ArduPilot's Antenna Tracker firmware has been making some quiet progress over the past few months. They're all documented in the …Continue
Copter-3.4-rc1 has been released for beta testing and can be downloaded using the Mission Planner's Install Firmware screen's beta firmware link. Some of the changes since Copter-3.3.3 are listed below.
1) EKF2 allows "boat mode" (attitude initialisation without gyro calibration)
The upcoming Copter-3.4 release will include terrain following support for mission commands using either Google earth altitude data or a Laser Range Finder. This is a demonstration video shot at a ski hill near my home in Karuizawa Japan of this new feature.
For this test I used a venerable 3DR IRIS with a …Continue
After months of testing by the beta-testing team, Copter-3.3 is ready for wider use. Similar to the Copter-3.2 release this is a "soft launch" meaning that for the next couple of weeks, we are asking users to load the new version using the Mission Planner's "Beta firmwares" link…Continue
The video above shows my first attempt (which was successful) to fly APM:Copter using a Linux board (…Continue
Warning: there was a period of about 12 hours after this blog was first posted where an older version (AC3.1.2) replaced AC3.2.1 for APM2. If you think you may have downloaded for the APM2 during these initial period, please check the version on your board by looking at the title bar of the Mission Planner (see…Continue
ArduCopter 3.2 (aka APM:Copter) has been released as the default version replacing AC3.1.5. This is the exact same version that we invited all users to test two weeks ago. Users who wish continue using AC3.1.5 can find it under the "Pick…Continue
After months of testing, ArduCopter 3.2 (aka APM:Copter) is ready for widespread use and we invite all users to give it a try. In order to manage the support load at first it will be available only through the Mission Planner and APM Planner2's Beta Firmwares link. This link is visible from the regular "Install Firmware" page if you check…Continue
AC3.1 is going out very soon and includes a new safety feature called GPS glitch detection. There's a wiki page about it but I'd like to highlight how it works because it's near the top of the list of safety issues. The method itself comes from …Continue
Two years after the March 11th tsunami in Japan that triggered the Nuclear disaster at the Fukushima power plant, there are still just over 300 thousand people who have not been able to return to their homes due to high radiation levels. The government has decided that radiation…Continue
For those interested in using their multicopters to carry heavy objects you might be interested in the test that I performed today with Assistant Professor Nagatani-san of Tohoku university in Japan and Izu-san of…Continue
I received a 2D laser range finder from the good people at Hokuyo more than 1 year ago. My plan was to try to use it to improve ArduCopter's altitude hold or collision avoidance but other priorities have taken up my…Continue
Most of the pro multicopter set-ups have feedback from the ESCs so the controller knows the status of the motors. This is useful for all kinds of reason including:
1. debugging the causes of crashes - the controller could log when a motor has stopped running.
2. allows faster and better reaction to a motor failure perhaps saving you from a crash at least for…Continue
