ROSCon 2018 Diversity Program

ROSCon 2018 marked the third year of the conference’s diversity program, which is designed to enable participation in ROSCon by those typically underrepresented in the tech community. Thanks to the support of the program’s sponsors Amazon, Apex.ai, Erle Robotics, Fetch Robotics, Google, Locus, Open Robotics, and SICK, we were joined at the conference by close to 30 roboticists from around the world who otherwise wouldn’t have made it to Madrid. Our hope is that, like all attendees of ROSCon, the scholarship recipients will return home after the event to share the knowledge and networks that they’ve acquired in order to strengthen their local ROS communities.

To get a sense of the impact that the ROSCon Diversity Scholarship Program had this year, we’re proud to share some comments from scholarship recipients about their experience about the conference and the ROS community as a whole:

ROSCon has been an incredible experience. It is really encouraging to see that everyone in the robotics community is really welcoming and willing to share their expertise. I learned a lot and I met incredible people. This experience inspired and motivated me to contribute more to the robotics community and make a positive impact. This would not be possible without the generous support from the scholarship sponsors. Your generosity truly makes a difference. Thank you!

My attendance at ROSCon 2018 has given me useful insight into the breath of the user base behind ROS, and close contact with the community that make ROS work. This access has deepened my interest in ROS and the world of robotics and I gained useful insight on how to progress my research into ROS and the application of robotics in my profession as an architect while talking with people I met at the conference who were all friendly and eager to offer information and tips. Along with all the great people from all over the world, I met 3 other Nigerians involved in robotics and of the four of us, I was the only one currently resident in Nigeria. With robotics being such a rare field in Nigeria, it revealed the potential for the diversity scholarship to draw out globally dispersed ROS users from the same region and connect them at an international platform. This creates more opportunities for future collaboration and knowledge transfer.

The scholarship program continues to grow each year, and so outside of the standard conference schedule we also host a reception for the diversity program prior to the event. This provides an opportunity for scholarship recipients to connect with the sponsors of the program that have helped fund their attendance.

A big thank you goes out to the scholarship recipients for helping us make ROSCon more representative of the global and diverse ROS community, and to the ROSCon Diversity Committee and the conference’s diversity program sponsors, without which this wouldn’t have been possible:

ROS (t-shirts) through the years

We began the tradition of making t-shirts to commemorate significant events in the development of ROS back in 2009 when we working through Milestones 1, 2, and 3 as part of getting the PR2s ready to ship. When we started releasing ROS distros, we also started working with artist Josh Ellingson. Josh has done the logos for all the ROS distros and conferences we’ve had since then.

With ROSCon 2018 just a few days away, we thought that it’d be fun to look back through the past decade of ROS development, in t-shirt form, so we asked everyone to go digging through their closets:

We hope to see you in Madrid this weekend!

Taking ROS and Gazebo into healthcare
NNM_0809.jpg

As we shared in March, Open Robotics is now operating a research and development office in Singapore. This week, at the 2018 National Health IT Summit, Minister of Health Gan Kim Yong announced our initial project for the Singapore office: the Robotics Middleware Framework (RMF). After Mr. Gan's announcement, our own Brian Gerkey introduced the audience to Open Robotics and explained what we'll be building and why.

As more robotics and automation technologies are introduced to healthcare, interoperability should be front and center for every manufacturer, systems integrator, and end user. No single vendor can supply the breadth of solutions that are required in a modern healthcare facility and no single facility can afford to operate a collection of siloed systems with vendor-specific interfaces.  We need food-delivery robots from one vendor to communicate with drug-delivery robots from another vendor. We need a unified approach to command and control for all the robots in a facility. We need a reliable way to develop and test multi-vendor systems in software simulation prior to deployment. And for it to succeed we need this critical interoperability infrastructure to be open source.

Under the leadership of the Centre for Healthcare Assistive and Robotics Technology (CHART), we are working over the next three years with government and industry partners to develop the Robotics Middleware Framework. In this program we will improve, extend, and scale up ROS and Gazebo to provide a common and open system with which we can interconnect, monitor, command, and simulate the thousands of robots and other devices that are already used in modern hospitals as well as create a scalable system which can support solutions that are not yet designed.

By applying the philosophical and technical approaches that have led to the widespread adoption of ROS and Gazebo in so many other robotics markets, we are excited to bring openness and interoperability to the advanced technology that is poised to change how healthcare is administered.

If you'd like to help us in this effort, remember that we're hiring here in Singapore!

ARIAC 2018 Finals results announced

We are happy to announce the final results of the 2018 Agile Robotics for Industrial Automation Competition (ARIAC), hosted by the National Institute of Standards and Technology (NIST).

Now in its second year, ARIAC is a simulation-based competition designed to address a critical limitation of robots used in industrial environments: that they are not as agile as they need to be. Many robots are not able to quickly detect failures, or recover from those failures. They aren’t able to sense changes in their environment and modify their actions accordingly. The goal of ARIAC is to enable industrial robots on workshop floors to be more productive, more autonomous, and more responsive to the needs of shop floor workers by utilizing the latest advances in artificial intelligence and robot planning.

While autonomously completing order fulfillment tasks, teams were presented with various agility challenges developed based on input from industry representatives. These challenges include:

  • Failing suction grippers, requiring teams to determine if products dropped from the gripper should be retrieved or re-positioned,

  • Reception of updated/high-priority orders, prompting teams to decide whether or not to reuse existing in-progress shipments being filled or to start new ones from scratch,

  • Notification of faulty products, requiring teams to replace inadequate products and plan ahead to ensure enough non-faulty products are available for the high priority orders,

  • Products requested flipped from their original positioning, requiring teams to complete a two-step process to place the product, and

  • Failing sensors, requiring teams to have a high-level model of the environment to continue working through a complete sensor “blackout.”

Teams had control over their system’s suite of sensors positioned throughout the workcell, made up of laser scanners, depth cameras, intelligent vision sensors, quality control sensors and interruptible photoelectric break-beams. Each team chose a unique sensor configuration with varying associated costs and impact on the team’s strategy. Teams that focused on sensors requiring a higher level of processing -- for example, depth cameras in place of intelligent vision sensors -- gained a points boost for their overall lower system cost. The effect of this aspect of the competition was in full swing in the Finals, with the top two teams choosing sensor configurations that had only a single sensor in common.

The virtual nature of the competition enabled participation of teams affiliated with companies and research institutions from a range of countries. The diversity in the teams’ strategies to solving the agility challenges can be seen in the video of highlights from the Finals:

Scoring was performed based on a combination of efficiency, performance and cost metrics over 15 trials. Additionally, judges awarded points for novel, industry-implementable approaches to solving the agility challenges. The overall standings of the finalist teams are as follows.

The top three eligible teams will receive cash prizes.

Top-performing teams will be invited to present at an upcoming workshop that will be open to all, including those that did not participate in ARIAC. In addition to showcasing the various approaches used in the competition, we will also be exploring plans for future competitions. If you are interested in giving a presentation about agility challenges you would like to see in future competitions, please contact Craig Schlenoff (craig.schlenoff@nist.gov).

Congratulations to all teams that participated in the competition!

Service Robot Simulator

In the past few months, Open Robotics worked together with Hitachi on a virtual robotics competition called ServiceSim, which focuses on human-robot interaction in an office environment. Competitors must control the ServiceBot robot to perform tasks such as finding a human guest and guiding them to their destination, while making sure the guest doesn't get lost.

The competition runs on Gazebo 8 and ServiceBot is controlled using ROS Kinetic. All the competition software, including all the SDF models of the office, from cubicles to bathrooms and coffee makers, have been released as open source, so anyone is welcome to reuse these for their own environments. The competition environment itself is also versatile and competitors can customize the task and practice in various scenarios.

Several improvements have been made to the simulation of human characters in Gazebo: they now have the ability to collide with objects in simulation and there are new plugins to make the human actors run or walk in given trajectories or while following a given target, with plenty of configuration options.

ServiceBot was modeled from scratch and its URDF description and ROS controllers are available along with the competition software. In addition, a reference solution to the competition which uses the ROS navigation stack and exercises the competition's ROS API, reading sensor data and controlling the robot, is offered as a starting point for competitors.

Hitachi and Open Robotics invite the community to try out the competition software, develop their own solutions to the tasks and try completing the competition with their own robots! Debian packages are available for Ubuntu Xenial or you can use Docker for convenience. Take a look at the tutorials to get started!

Going Underground

If you haven't already heard of the DARPA Subterranean Challenge (or "SubT"), it's time to start paying attention.

With SubT, DARPA "aims to develop innovative technologies that would augment operations underground. The SubT Challenge will explore new approaches to rapidly map, navigate, search, and exploit complex underground environments, including human-made tunnel systems, urban underground, and natural cave networks."

DARPA announced SubT back in December, but Program Manager Dr. Timothy Chung recently announced that Open Robotics has been charged with creating and running the simulated track of the challenge.

Unlike our involvement in the DARPA Robotics Challenge in which we created a simulated environment in Gazebo for a single robot – the Atlas, SubT allows for a wide variety of robot participants.

You can read more about it in today's Wired: DARPA'S Next Challenge? A Grueling Underground Journey

DARPA will be announcing more details at the SubT Challenge kickoff in Fall 2018.

We're located in Block 81, which is part of a complex specifically designed for startups and other small companies, complete with a faux-repurposed-industrial look to the buildings and the nearby Timbre+,  which is a kind of mash-up of hawker market, food truck, and hipster bar. We're looking forward to getting to know our neighbors in the other companies that are operating nearby.

We'll be posting open positions for the Singapore office soon, so if you're in that part of the world and want to join the Open Robotics team, stay tuned!
