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. ®

  • ESA boss gives update on stricken Sentinel-1B imaging satellite: All is not lost yet

    Still borked, 1C and 1D are waiting in the wings

    ESA Director General Josef Aschbacher has addressed the issue of the space agency's borked Copernicus Sentinel-1B spacecraft in his first annual press conference.

    The last useful bit of data from the Earth observation satellite came last year, and as of yesterday attempts to revive the equipment to normal working order have come to naught.

    It's an interesting anomaly: the spacecraft remains under control and, according to Aschbacher, "the thermal control system is properly working and the regular orbit control manoeuvres are routinely performed." However, attempts to reactivate the power unit that's holding back the transmission of image data have proven unsuccessful.

  • Tesla driver charged with vehicular manslaughter after deadly Autopilot crash

    Prosecution seems to be first of its kind in America

    A Tesla driver has seemingly become the first person in the US to be charged with vehicular manslaughter for a deadly crash in which the vehicle's Autopilot mode was engaged.

    According to the cops, the driver exited a highway in his Tesla Model S, ran a red light, and smashed into a Honda Civic at an intersection in Gardena, Los Angeles County, in late 2019. A man and woman in the second car were killed. The Tesla driver and a passenger survived and were taken to hospital.

    Prosecutors in California charged Kevin George Aziz Riad, 27, in October last year though details of the case are only just emerging, according to AP on Tuesday. Riad, a limousine service driver, is facing two counts of vehicular manslaughter, and is free on bail after pleading not guilty.

  • AMD returns to smartphone graphics with new Samsung chip for your pocket computer

    We're back in black

    AMD's GPU technology is returning to mobile handsets with Samsung's Exynos 2200 system-on-chip, which was announced on Tuesday.

    The Exynos 2200 processor, fabricated using a 4nm process, has Armv9 CPU cores and the oddly named Xclipse GPU, which is an adaptation of AMD's RDNA 2 mainstream GPU architecture.

    AMD was in the handheld GPU market until 2009, when it sold the Imageon GPU and handheld business for $65m to Qualcomm, which turned the tech into the Adreno GPU for its Snapdragon family. AMD's Imageon processors were used in devices from Motorola, Panasonic, Palm and others making Windows Mobile handsets.
