When using the Robot Operating System (ROS), it’s fairly common to want to shut down a launched system if a specific node (or set of nodes) exits. This is pretty easy in ROS1, because launch files support the required attribute on each node. As a result, crafting a two-node system where one of the nodes

The snapcraft CLI has supported building ROS1 snaps for a while via the catkin plugin. We supported the ROS2 betas via the ament plugin, but that was before Open Robotics had a ROS2 package repository setup, which meant that the ament plugin built the ROS2 underlay from source, and it was predictably dreadfully slow. However,

Robots are an increasingly important part of our lives, in more ways than we realise. I’m not talking just about Roombas, or the toy robots that inhabit the wish lists of the world’s children (and the young at heart). Robots are increasingly behind the scenes, powering the modern world we experience daily. From clothing to

This is the fifth (and final) blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we discussed methods of control, did a little math, and wrote the ROS driver for our robot. But it still required several nodes to be running at once, and sharing

This is the fourth blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we worked on getting data out of the wireless controller and into ROS in a format meant for controlling differential drive robots like ours: the Twist message. Today we’re going to create

This is the third blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post you were introduced to the Robot Operating System (ROS), and got your robot moving by ROSifying one of the CamJam worksheets. Today we’re going to move beyond the CamJam worksheets, and work

This is the second blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we walked through all the hardware necessary to follow this series, and introduced Ubuntu Core, the operating system for IoT devices. We installed it on our Raspberry Pi, and used it to

Some time ago I created a blog/video series that walked the reader through creating a prototype using the Robot Operating System (ROS) and taking it to production using Ubuntu Core. However, that series was intended more for robotics professionals; it assumed quite a bit of ROS knowledge, and required some costly equipment (the robot was

Please note that this blog post has outdated technical information that may no longer be correct. For latest updated documentation about robotics in Canonical please visit https://ubuntu.com/robotics/docs. My background is pretty heavily littered with robotics. A natural side effect of this is that I’ve published numerous posts discussing

One of the key tenets of snaps is that they bundle their dependencies. The fact that they’re self-contained helps their transactional-ness: upgrading or rolling back is essentially just a matter of unmounting one snap and mounting the other. However, historically this was also one of their key downsides: every snap must be standalone. For

Previous Robot Operating System (ROS) releases only supported i386, amd64, and armhf. I even tried building ROS Indigo from source for arm64 about a year ago, but ran into dependency issues with a missing sbcl. Well, with surprisingly little fanfare, ROS Kinetic was released with support for arm64 in their prebuilt archive! I thought it

Parrot collaborates with Canonical to launch the Parrot S.L.A.M.dunk, a new development kit for the creation of autonomous and obstacle avoidance drones and robots. Powered by Ubuntu and ROS (Robot Operating System), it gives developers a familiar environment to prototype solutions such as autonomous driving, 3D mapping, or simply using t

IoT World: Hybrid, Erle and Canonical combine to commercialize IoT dev ROSCon: Canonical demonstrates power of apps on robots; shows Erle Spider Mark Shuttleworth keynote at ROSCon: secrets to ROS success   Canonical is taking its Internet of Things (IoT) innovation on tour over the few days; bringing a host of new developments to the

This is a guest post by the Erle-Robotics team as part of “the startup stories”, a series of blog posts about how and why innovative companies are using Ubuntu technology. Erle-Spider as the first legged drone powered by ROS and running snappy Ubuntu Core. This smart robot with a 900 MHz quad-core ARM Cortex-A7 processor

If you are into robot spiders then the erle-spider is something to look forward to. It will be the first app-enabled Snappy Ubuntu Core and ROS powered robot spider. Curious to see what people will do with it  

Drones are getting Snappy Autopilot Apps. On Indiegogo you can contribute to the PixHawk Fire (PXF). The PixHawk Fire (PXF) is an open hardware cape (daughter board) for the BeagleBone Black that allows you to create Snappy autopilot apps for drones. Behind the cape there is Erle Robotics, a startup based in Spain and led
