ROS on Windows 10

Is 2018 Finally The Year Of Windows On The Robot?

October 9, 2018 by 52 Comments

Microsoft is bringing ROS to Window 10. ROS stands for Robot Operating System, a software framework and large collection of libraries for developing robots which we recently wrote an introductory article about, It’s long been primarily supported under Linux and Mac OS X, and even then, best under Ubuntu. My own efforts to get it working under the Raspbian distribution on the Raspberry Pi led me to instead download a Pi Ubuntu image. So having it running with the support of Microsoft on Windows will add some welcome variety.

To announce it to the world, they had a small booth at the recent ROSCon 2018 in Madrid. There they showed a Robotis TurtleBot 3 robot running the Melodic Morenia release of ROS under Windows 10 IoT Enterprise on an Intel Coffee Lake NUC and with a ROS node incorporating hardware-accelerated Windows Machine Learning.

Why are they doing this? It may be to help promote their own machine learning products to roboticists and manufacturing. From their recent blog entry they say:

We’re looking forward to bringing the intelligent edge to robotics by bringing advanced features like hardware-accelerated Windows Machine Learning, computer vision, Azure Cognitive Services, Azure IoT cloud services, and other Microsoft technologies to home, education, commercial, and industrial robots.

Initially, they’ll support ROS1, the version most people will have used, but also have plans for ROS2. Developers will use Microsoft’s Visual Studio toolset. Thus far it’s an experimental release but you can give it a try by starting with the details here.

Modular Robotics Made Easier With ROS

May 31, 2018 by 31 Comments

A robot is made up of many hardware components each of which requires its own software. Even a small robot arm with a handful of servo motors uses a servo motor library.

Add that arm to a wheeled vehicle and you have more motors. Then attach some ultrasonic sensors for collision avoidance or a camera for vision. By that point, you’ve probably split the software into multiple processes: one for the arm, another for the mobility, one for vision, and one to act as the brains interfacing somehow with all the rest. The vision may be doing object recognition, something which is computationally demanding and so you now have multiple computers.

Break all this complexity into modules and you have a use case for ROS, the Robot Operating System. As this article shows, ROS can help with designing, building, managing, and even evolving your robot.

Yellow Robot Wheels Rolling Out

April 1, 2018 by 2 Comments

Small wheeled robots are great for exploring robotics and it’s easier than ever to get started, thanks to growing availability and affordability of basic components. One such component is a small motorized wheel assembly commonly shown when searching for “robot wheel”: a small DC motor mounted in a gearbox to drive a single plastic wheel (inevitably yellow) on which a thin rubber tire has been mounted for traction. Many projects have employed these little motor + gearbox + wheel modules, such as these three entries for 2018 Hackaday Prize:

BoxBotics takes the idea of an affordable entry point and runs with it: build robot chassis for these wheels out of cardboard boxes. (Maybe even the exact box that shipped the yellow wheels.) Cardboard is cheap and easy to work with, making cardboard projects approachable to any creative mind. There will be an audience for something like a Nintendo Labo for robotics, and maybe BoxBotics will grow into that offering.

Cing also intends to make a friendly entry point for robotics and they offer a different chassis solution. Instead of cardboard, they use a circuit board. The yellow gearbox is mounted directly to the main circuit board making it into the physical spine, along with its copper traces serving as the spinal cord of the robot. While less amenable to mechanical creativity than BoxBotics, Cing’s swappable modules might be a better fit for those interested in exploring electronics.

ROS Starter Robot caters to those who wish to go far beyond simple “make it move” level of robot intelligence. It aims to lower the barrier to enter the world of ROS (robot operating system) which has historically been the domain of very capable (but also very expensive) research-oriented robots. This project could become the bridge for aspiring roboticists who wish to grow beyond hobbyist level software but can’t justify the cost typical of research level hardware.

All three of these projects take the same simple motorized wheel and build very different ideas on top of them. This is exactly the diversity of ideas we want to motivate with the Hackaday Prize and we hope to see great progress on all prize contestants in the month ahead.

Soon You’ll Sit Inside A Robot’s Head At Work

October 10, 2017 by 28 Comments

MIT’s Computer Science and Artificial Intelligence Lab, CSAIL, has created a process of teleoperating a Baxter humanoid robot with an Oculus Rift VR headset. This project is partially aimed towards making manufacturing jobs a hell of a lot of fun telecommutable. It could even be a way to supervise robot workers from a distance.

In a nutshell, the user controls the robot remotely in a virtual reality environment. The user does this specifically in a VR environment modeled like a control room with multiple sensor displays, making it feel like they are sitting inside the robot’s head. By using hand controllers, users can match their movements to the robot’s to complete various tasks. If you’ve seen Pacific Rim, you are probably envisioning a Jaegar right about now — minus the psychic linking.

Telepresence Robot 2000 Leagues Under The Sea

July 27, 2017 by 10 Comments

Telepresence robots are now a reality, you can wheel around the office and talk to people, join a meeting, see stuff and bump into your colleagues. But imagine if telepresence were applied to deep sea exploration. Today we can become oceanographers through the telepresence system created by Bob Ballard (known for locating the Titanic, discovered deep sea geothermal vents, and more) and his team at the Inner Space Center. Put on your Submariner wristwatch because its time for all of us to explore the ocean depths via the comfort of our home or office.

Simulate Your Robot Before You Build It

October 9, 2016 by 12 Comments

[Nurgak] shows how one can use some of the great robotic tools out there to simulate a robot before you even build it. To drive this point home he builds the tutorial off of the easily 3D printable and buildable Robopoly platform.

The robot runs on Robot Operating System at its core. ROS is interesting because of its decentralized and input/output agnostic messaging system. For example, if you leave everything alone but swap out the motor output from actual motors to a simulator, you can see how the robot would respond to any arbitrary input.

[Nurgak] uses another piece of software called V-REP to demonstrate this. V-REP is a simulation suite for robotics and has a few ROS nodes built in. So in order to make a simulated line-following robot, [Nurgak] tells V-REP to send a simulated camera image to the decision making node of the robot in ROS. It then sends the movement messages back to V-REP which drives the pretend robot around.

He runs through a few more examples, proving that it’s entirely possible to become if not a roboticist, at least a really good AI programmer without ever dropping the big money on parts to build a robot.

Intel Makes A Cool Robot Brain In Latest Attempt To Pry Hackers From Their Wallets

August 26, 2016 by 25 Comments

Hackerboards got a chance to sit down with Intel’s latest attempt to turn hackers into a willing and steady revenue stream, the, “Euclid.” The board is cool in concept, a full mini computer with stereo cameras, battery, Ubuntu, and ROS nicely packaged together.

We would be more excited if we knew how much it costs, but in principle the device is super cool. From a robotics research perspective it’s a sort of perfect package. ROS is a wonderful distributed and asynchronous robotic operating system, test, and development platform. The Intel developers designed this unit around the needs of ROS and it comes pre-installed on the camera.

For those who haven’t used ROS before, this is a really cool feature. ROS is natively distributed. It really doesn’t care where the computer supplying its data lives. So, for example, if you already had a robot and wanted to add stereo vision to it. You could offload all the vision processing components of your existing ROS codebase to the Euclid and continue as if nothing changed.

The other option is to use the board as the entire robot brain. It’s self contained with battery and camera. It’s a USB to serial connection away from supercharging any small robotics project.

Unfortunately the board is still a demo, and based on Intel’s history, likely to be too expensive to lure ordinary hackers away from the RasPis and import cameras they already know how to hack together into more or less the same thing. Universities will likely be weak at the knees for such a development though.
