Penguin high-flyers: Andrew Tridgell on the Linux autopilot
The only way is up for open source, says ArduPilot dev
Vid The indefatigable Andrew Tridgell popped up at linux.conf.au in new Zealand last week, where he delivered an entertaining presentation on the state of play of porting ArduPilot to Linux.
ArduPilot is the open source software which controls our own Vulture 2 spaceplane on the 3DR Pixhawk autopilot. As Tridge demonstrated, it can now be deployed on a range of hardware which, with the addition of a suitable interface, allows aficionados to create a fully-functioning autopilot.
Last year, for example, a group of Russians successfully raised funds for the Navio, an autopilot shield for the Raspberry Pi.
As part of his talk, Tridge connected live to a model aircraft in Canberra, in this case equipped with an embedded Linux box - the BeagleBone Black - coupled to a PixHawk Fire Cape (PXF).
This hook-up was of particular interest to the Low Orbit Helium Assisted Navigator (LOHAN) team since our own flight in New Mexico will feature a similar remote link, with Tridge on his sofa in Canberra monitoring the Vulture 2's status in real time.*
It's audacious stuff, and Tridge's linux.conf.au outing demonstrated just how quickly open source autopilot tech is moving. Evidently, porting ArduPilot to Linux is just part of a wider movement towards small vehicles running on the OS, and the Linux Foundation last year announced the launch of the Dronecode open source UAV platform project.
Tridge, meanwhile, will be at the Embedded Linux Conference in San Jose, California, at the end of March, where he'll be talking some more about ArduPilot on Linux and Dronecode. ®
