The State of Robotics – November 2020

Goodbye Thanksgiving (well, for some of us), hello Christmas! The holiday season really is the best, and it always brings interesting robotics news, which we will now distill into a quick dose of delightful and easily-digestible tidbits. As always, if you’d like to see your work showcased here, please send an email to robotics.community@c

The State of Robotics – August 2020

So that’s the summer gone (hopefully, that heat was awful). Or winter if that’s where you are. Seasons change and so does the state of robotics. Fortunately, that’s what we’re here for. Before we get into it, as ever, If you’re working on any robotics projects that you’d like us to talk about, be sure

How to build a snap using ROS 2 Foxy

The snapcraft CLI (the tool used to create snaps) has long had support for building snaps that use both ROS 1 and ROS 2. ROS 2 Foxy Fitzroy is the latest ROS 2 LTS, which runs on Ubuntu 20.04 (Focal Fossa). The snapcraft CLI recently gained experimental support for building Foxy snaps, so I wanted

ROS 2 Foxy Fitzroy and its Enhanced Security Monitoring

We’re pleased to welcome the newest ROS 2 release, Foxy Fitzroy. A long-term support (LTS) release, (supported for three years), Foxy runs on the latest Ubuntu LTS, the also-recently-released Ubuntu 20.04 (supported for five years, or even longer with an ESM subscription). Putting together a distribution like Foxy is a ton of work. Open R

PSA for ROS users: Some things to know as Python 2 approaches EOL

We recently got an interesting question from a customer, and I think the answer might be helpful to a wider audience. Python 2 will reach end of life in two months. This shouldn’t be news to anyone who hasn’t been living under a rock, and plans are in place to use Python 3 in Noetic

Robotics security: What is SROS 2?

We at Canonical have been hard at work on the security features of version 2 of the Robot Operating System (ROS 2). However, if we lift our collective heads up out of the weeds it’s easy to see folks completely misunderstanding how security works today in ROS 2. We’ve written some design articles to help

Canonical joins the ROS 2 Technical Steering Committee

We at Canonical care deeply about robotics. We firmly believe that robots based on Linux are cheaper to develop, more flexible, more secure, and faster to market. One of the contributing factors to this being the case is the Robot Operating System (ROS). ROS is by far the most popular middleware for creating Linux-powered robots.

Speed up your ROS snap builds

A while back I wrote a post about distributing a ROS system among multiple snaps. If you want to enable some sort of add-on story, you need to have multiple snaps, and that remains the way to do it today with ROS. That approach works, but I’ll be the first to admit that it’s not

ROS 2 launch: required nodes

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

Building ROS 2 snaps with Colcon

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,

Your first robot: Sharing with others [5/5]

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

Your first robot: The driver [4/5]

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

Your first robot: The controller [3/5]

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

Snapcraft Summit summary – day 3

The third day of the Snapcraft Summit here in Seattle saw all the developers reconvene and really get down to work, and ROSHub came by in the afternoon with their snap-powered robots! Strictly-confined snaps can only access specific areas on disk that are defined by the interfaces they utilize. This works well, but can occasionally

Snapcraft Summit summary – day 2

The second day of Snapcraft Summits tend to be particularly productive as all the participants get more familiar with each other, and this one is no exception. In addition to developers from CircleCI, Electron, Microsoft, Plex, and Slack, today saw the addition of our friends from ROSHub joining us to hack on their snaps. Snapcraft

Your first robot: Introduction to the Robot Operating System [2/5]

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
