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.

Third Robotics and ROS in Zürich Meetup

The third robotics and ROS in Zürich meetup was organized and hosted by ICCLab on June 19th 2019. There was a good turnout from representatives in both academia and industry, totaling about 25 people in attendance. For our third meetup we had two presentations: “Perception and action planning in complex environments with ROS” by Rastislav Marko and Martin Möller from F&P Personal Robotics and “Self-calibrating camera position and grasping with Niryo arm” by Dimitrios Dimopoulos from ICCLab, ZHAW.

Martin Möller opened the first talk with a brief introduction of the company and one of its collaborations with ZHAW in the past. Next an overview of the hardware components of P-Rob 2R was given. This robot lies at the heart of the company’s solutions, including Lio, a mobile service robot, which was the focus of the talk. Following that, myP, the core robot library with its accompanying graphical control interface, was presented in action and a quick look at its architecture and configuration was showcased. Finally, Martin mentioned the key sensor components used by the mobile service robot.

Second Robotics and ROS in Zürich Meetup

The second robotics and ROS meetup in Zürich was organized by ICCLab and hosted by Dr. Romana Rust and Gonzalo Casas from Gramazio Kohler Research, ETH Zürich, on May 14th 2019. There was a good turnout from representatives in both academia and industry, totaling about 45 people in attendance. For this second meetup we had three presentations: “ROS for Digital Fabrication in Architecture”, “ROS Integration into Magic Leap” and “Next Generation Security” from Wecorp.

Summary of presentation #1: ROS for Digital Fabrication in Architecture by Dr. Romana Rust and Gonzalo Casas from ETH Gramazio Kohler Research group

Dr. Romana Rust opened the first talk by showcasing ongoing and past projects of the Gramazio Kohler Research group. Specifically she presented the usage of industrial grade robots and ROS in additive digital fabrication and the ways they allow for a novel approach in building non-standardized architectural components.

Niryo Arm Motor Troubleshooting

In most development processes hiccups are unavoidable. Our grasping application using the Niryo One arm was no exception. During testing, we had two of our arms break down and with this post, we would like to share our experiences with debugging and resolving these issues.

As far as we can understand, the axis 6 motor (Dynamixel XL-320 model) in the first arm, which is responsible for turning the gripper around, was damaged due to the gripper hitting the table. Since the gripper does not have an applied force feedback shutdown procedure, one of the motors probably broke down from overloading. Note that there is no gripper URDF model provided and octomap integration into the project was not yet complete at the time, so the kinematics planner was not aware of the table’s existence. As for our second arm, the culprit was the power adapter. The Dynamixel XL-430 motors are rated for 11.1 Volts, but the adapter supplied is a 12V one, which can cause permanent damage due to overheating if the arm is operating for prolonged periods of time. This design oversight was amended in Niryo One models shipped after November 2018, but in any case, you should check the rating of the power adapter provided and request a replacement if needed.

First Robotics and ROS in Zürich Meetup

ICCLab organized the first robotics and ROS meetup in Zürich on April 9th 2019. There was a good turnout from representatives in both academia and industry, totaling almost 60 people in attendance. This meetup is the first of hopefully many that we intend to organize, as part of our effort to build a local network of ROS users across many robotic disciplines. Besides networking, our goal for these meetups is to also provide a platform for individuals to share and teach specific robotics/ROS knowledge. For this initial meetup we had two presentations: vision for navigation in autonomous robotics, and ROS applications at ICCLab.

Nearly 60 attendees were present at the first robotics and ROS in Zürich meetup.

Running the ICCLab ROS Kinetic environment on your own laptop

As we are making progress on the development of robotic applications in our lab, we experience benefits from providing an easy-to-deploy common ROS Kinetic environment for our developers so that there is no initial setup time needed before starting working on the real code. At the same time, any interested users that would like to test and navigate our code implementations could do this with a few commands. One git clone command is now enough to download our up-to-date repository to your local computer and run our ROS kinetic environment including a workspace with the current ROS projects.

To reach this goal we created a container that includes the ROS Kinetic distribution, all needed dependencies and software packages needed for our projects. No additional installation or configuration steps are needed before testing our applications. The git repository of reference can be found at this link: https://github.com/icclab/rosdocked-irlab

Configuring the ROS Navigation Stack on a new robot

Our lab has acquired a new robot as part of its ROS based robotic fleet. We opted with the SUMMIT-XL Steel from Robotnik; a behemoth compared to our much-loved TurtleBots.

The Summit-XL Steel is advertised to be a great platform for robotic application that require transporting heavy loads (up to 250 kg) such as warehouse automation (retrieved from https://www.robotnik.eu/web/wp-content/uploads//2018/07/Robotnik_SUMMIT-XL-STEEL-01.jpg).

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.

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).
