Fourth Robotics and ROS in Zurich Meetup

On Wednesday’s evening, 16th of October we attended a 4th Robotics and ROS in Zurich meetup. I was our first meetup after the summer break. This time, it was co-organized by ICCLab and ANYbotics. ANYbotics provided their office space for the meeting and demo. We managed to gather together around 50 interested attendees.

Everything started with a short introduction talk and agenda presentation by Giovanni Toffetti. After that, the ANYbotics team gave a 30min long presentation about their flagship robot – ANYmal C.

ANYmal C legged robot presentation

Peter Frankhauser, the CBDO of ANYbotics, started by explaining the current state of the art of mobile robots and presenting possible paths where the robotic industry is going to expand in the future. He showed that by analyzing the history of the mobile robotics industry we can spot a transition from robots performing repetitive tasks (automation), started by the third industrial revolution in late 60s, to autonomous robots used to operate in large storehouses (logistics). The autonomy of logistic robots is somehow limited only to controlled environments, so by drawing a trend line, we can spot the next breakthrough waiting to be reached by mobile robots: the possibility to operate autonomously in “robot unfriendly” environment. The use-case presented by ANYbotics team is the task of routine inspections in places like offshore power plants or oil platforms. Later on, two engineers from ANYbotics, took over the presentation and dived more deeply into technical details about how they managed to adapt their robot to harsh environment and what kind of challenges they faced.

Some Cloud Robotics News

We haven’t updated the blog with robotics news in a while, but we actually have plenty to tell and much more to come soon.

First of all the robotics team has gained new strength with the addition of Andy, Dimitris, Leo, Rod, and Thomas. Tobi and Lukasz have left us, but we are still working on collaborating remotely.

On top of amazing people, the team has grown also in terms of robots. From the month of October we have finally started receiving our new robotic hardware and got to play with it.

KubeCon’18 – Cloud, containers, edge, nets, robots, and philosophy of science

KubeCon / CloudNativeCon Europe 2018 took place at the shiny Bella Center of Copenhagen on May 2 – 4, 2018.
Here at ICCLab/SPLab we use extensively Kubernetes / CNCF technologies both in teaching and research, but we had one extra reason for being there this year: our friends and colleagues from Rapyuta Robotics (RR) were scheduled to give a talk on Cloud Robotics PaaS.

Openshift 3.6 on Openstack – developer cluster setup

The ECRP Project uses Kubernetes/Openshift as the base for its Cloud-Robotics PaaS.  Apart from running robotic applications distributed across robots and clouds, we wanted to assess whether latency to the closest public data-center (Frankfurt for both AWS and GKE) would be low enough to run common SLAM and navigation apps. The short answer is YES, although our work there continues.

Thanks to the work of Seán, Bruno, and Remo, the ICCLab has a brand new Openstack cluster. The Cloud-Robotics crew decided to take it for a spin, and use some research grant money on public clouds also for other activities (e.g., FaaS / Serverless computing).

Paraguayan Perspective on Cloud Applications

by Josef Spillner

The Itaipu Technology Park (PTI) in Paraguay, founded in 2009, is involved with scientific and technological development which contributes positively to regional development. Several of its centres with a total number of 90 engineers and researchers put emphasis on ICT integration and the challenges connected with it. Among them are diverse plans to use cloud applications. In this context, the Service Prototyping Lab of Zurich University of Applied Sciences (SPLab) in Switzerland is conducting a two-week guest lecturing and research exchange presenting its research initiatives and outputs on the PTI premises in close proximity to Ciudad del Este.

The intricacies of running containers on OpenShift

by Josef Spillner

In the context of the ECRP Project,  which is part of our cloud robotics initiative, we are aiming to build a PaaS solution for robotic applications.

The “Robot Operating System” (ROS) is widely used on several robotics platforms, and also runs on the turtlebot robots in our lab. One of the ideas behind cloud robotics is to enable ROS components (so called ROS nodes) to run distributed across the cloud infrastructure and the robot itself, so we can shift certain parts of the robotics application to the cloud. As a logical first step we tried to run existing ROS nodes, such as a ROS master in containers on Kubernetes, then we tried to use a proper Platform as a Service (PaaS) solution, in our case Red Hat OpenShift .

OpenShift offers a full PaaS experience, you can build and run code from source or run pre-built containers directly. All of those features can be managed via a intuitive web interface.

However, OpenShift imposes tight security restrictions on the containers it runs.
These are:

  • Prevention from running processes in containers as root
  • Using random user ID for running containers (Support Arbitrary User IDs)

Impressions from ROSCon and IROS 2016

Two of the most influential robotics events of 2016, ROSCon and IROS, were conveniently co-located in South Korea during the second week of October.
We had previously attended ROSCon 2015 in Hamburg, but it was our first time at the International Conference on Intelligent Robots and Systems (IROS), this year in Daejeon.

Enterprise Cloud Robotics Platform transfer project

Title: ECRP – Enterprise Cloud Robotics Platform

Industry Partner: Rapyuta Robotics

Research Partner: SPLab/ICCLab, ZHAW

Funded ByCommission for Technology and Innovation

Summary:
The ECRP project combines cutting edge robotics technology from Rapyuta Robotics (RR), an ETH Zurich spinoff, and novel cloud development from the Service Prototyping (SPLab) and InIT Cloud Computing Lab (ICCLab) at ZHAW.
With ICCLab, RR will transform its existing open source robotics platform from a prototype to a full-fledged cloud-native enterprise ecosystem for third-party applications combining physical devices with cloud-hosted functionality.
RR and ZHAW have agreed to release this work as open source software (OSS), under the label Rapyuta Core.

Multi-Tenant Process Management as Single User

by Josef Spillner

Operating system process management has traditionally been an activity at the system level. An init system starts processes at boot time, at random events, and at the user’s (well, root’s) request. Well-known init systems are systemd, openrc and the venerable sysvinit. Without the boot-time component, supervisor processes such as supervisord, runit, daemontools or r6 form another related set of applications with emphasis on automated restart which we have covered already in previous blog posts.

In PaaS environments, multi-tenancy is crucial and process managers need to support it beyond just showing the users owning the processes. While multiple tenants can be perfectly mapped to multiple system users, and information from these users can be aggregated with automation tools, the permission management can quickly become complex and, first and foremost, already requires root permissions to create new users. Therefore, we have explored in the context of the cloud robotics research initiative how to manage processes purely as an ordinary user, but still for multiple tenants. A real need to do so is the fact that by running applications on ROS, dozens of ROS nodes get spawned quickly, many spawning further subprocesses and, due to early terminations, additionally causing fully detached and zombie processes which, when also changing their process group id, do not share a relation anymore to the original application.

Robotic Service Management with Roboreg

by Josef Spillner

roboreg-busyWe all know this tedious situation: Plenty of mobile robots around us, and we’d just like to use one of them for a specific task, but we don’t know which one we should take, as they’re all regularly busy on their own. Perhaps this is not a likely scenario right now, but it will be in five or six years from now and it will require novel approaches of how we manage their functionality in terms of services they offer. The Cloud Robotics research initiative is thus looking into robotic device management not so much from a hardware perspective but more from an angle of assessing which robotic resources can be used to deploy or run services and value-added applications on single robots, fleets of robots, or hybrid cloud/fleet constellations. With Roboreg, a first tangible robot-specific registry concept has been realised. The tool will be explained in this blog post.
