    1) ROSCon 2019.
    roscon.ros.org
    INFO: ROSCon is happening next week from October 31st to November 1st. The talks lineup is quite exciting and I’ll definitely be following it. Usually there is a livestream of the talks, check out the conference page for updates.

    2) LaMa - A Localization and Mapping Library.
    GitHub
    INFO: Feels like this newsletter will need a “SLAM Solution of the week section” if I keep learning about SLAM libraries at the current rate! Regarding this library there was an interesting discussion about it on ROS Discourse where the author of the library presented it to the community. The thing that caught my attention the most is how little resources this library uses. The GitHub repository description mentions that Raspberry Pi 3 Model B+ is the minimum viable computer to run it.

    3) Humanoid Robot Has Joints That Inspire.
    Hackaday
    INFO: This article presents the LIMS2-AMBIDEX humanoid robot upper body developed by Researchers from IRIM Lab at Korea University of Technology and Education. The robot is driven using brushless motors and pulleys and I indeed found the wrist mechanism inspiring! In the comment a Hackaday user anil inverse provided a link to a GitHub repository that contains an stl model of the wrist mechanism that you can 3D print.

    4) Anki Patent Portfolio Is Now for Sale.
    The Robot Report
    INFO: Anki was a consumer robot manufacturer that close down earlier this year (as featured in Weekly Robotics #37). As reported in the article the patent portfolio of the company is now for sale. I’m still bummed about Anki closing down I had high hopes for it and wanted to experiment with it using vector_ros at one point.

    5) Robot Teaches Kids Hand Washing Skills in Rural India.
    IEEE Spectrum
    INFO: Usually the robots I feature in this newsletter are a bit more sophisticated than the current version of Pepe shown in the article, however I believe it can have quite a positive impact. The experiment with this robot took only 3 days but throughout this time the hand washing rate of students increased by 40%.

    6) Robert Williams (Robot Fatality).
    Wikipedia
    INFO: Let’s take a dark turn. This Wikipedia page describes the death of Robert Willimas, who died in 1979 in one of the Ford plants and is the first known human to be killed by a robot. According to Wikipedia the second person to be killed by a robot was Kenji Urada who at the time worked at Kawasaki Heavy Industries.

    2) Assembler Robots Make Large Structures From Little Pieces.
    MIT
    INFO: Benjamin Jenett, a PhD student at MIT had developed robots capable of assembling structures, while also in a way being a part of them. In the article this concept is called “relative robotics” and I can’t wait to see more projects like these.

    3) Kimera Library.
    GitHub
    INFO: Via the linked page: “Kimera is a C++ library for real-time metric-semantic simultaneous localization and mapping, which uses camera images and inertial data to build a semantically annotated 3D mesh of the environment. Kimera is modular, ROS-enabled, and runs on a CPU”. The ROS wrapper of this package contains launch files for a Realsense D435i camera. I’m really tempted to try it out.

    4) Stanford Engineers Develop New Tool for Designing Prosthetic Limbs.

    6) LIPO Batteries Fail Explosion Compilation How Not to Burn Down your Home.
    YouTube
    INFO: I might have fallen into a YouTube rabbit hole of RC models crashing and what not and thought it would be a good idea to to talk safety again. I think being reminded every now and then that the LiPO batteries can catch fire if not handled properly is a good thing. Stay safe!

    7) Publication of the Week - Solving Rubik’s Cube With a Robot Hand (2019).
    arXiv
    INFO: This paper presents the work of OpenAI Researchers on creating a whole system capable of solving a Rubik’s cube with a humanoid robot hand that made the news this week. The setup for this project looks quite interesting, starting with Shadow Robot Dexterous Hand, a motion capture system to track the hand’s fingertips, RGB cameras for vision pose estimation and bluetooth enabled Rubik’s Cube. To train the model the Researchers used ADR (Automatic Domain Randomization) in simulation. My favourite part of the paper is when the AI gets annoyed: “We also observe that the policy appears more likely to drop the cube after being stuck on a challenging face rotation for a while”. You can find the video of the hand solving the cube on YouTube.

    Have you seen this video of Waymo employees testing the self driving car on their commutes? According to the description in the video the feature tested at the time was similar to highway assist features (assuming not very close to full autonomy). I feel I agree with the point made in the description that “nothing short of full autonomy will do”; I’m starting to agree - most of us will most probably be too distracted if they are not fully engaged.

    0) Weekly Robotics Q3 Reports.
    Weekly Robotics
    INFO: Do you like numbers? I made a Q3 report summarizing the newsletter performance in the last quarter. Hope you like it!

    1) Unleash Your Smart-home Devices: Vacuum Cleaning Robot Hacking.
    media.ccc.de
    INFO: Apparently smart vacuum cleaners made by Xiaomi run Ubuntu 14.04. I was hoping that the robot would run ROS however nothing I’ve seen in the video and project repository seems to indicate that they are using ROS. Using information from this GitHub repository and applying the things shown in the above video you can install a xiaomi_bridge and “rosify” your vacuum cleaner.

    2) Fictiv Teardowns.
    YouTube
    INFO: Big thanks to Illia for sending me these links! Apparently Fictiv does some teardowns of robots; in the above video you can see how a $300 iRobot Braava Robot Mop is built. On YouTube you can also find teardowns of Anki Vector, Neato Robot Vacuum and Roomba 650.

    3) mjbots quad A0.
    Hackaday
    INFO: mjbots quad A0 is an open source quadruped robot, very similar to MIT mini cheetah] that you could read about in the issue #28.

    5) Controlling Robots Across Oceans and Space – No Magic Required.
    ESA
    INFO: A signal from ISS to earth needs to make a round trip of 144 400 km. Assuming that the signal travels at a speed of light then we are dealing with 0.5 second delay. If you want to add haptic feedback to teleoperation I imagine it can be quite a tough issue to tackle, especially from user interface perspective. This article from ESA explores the history of robot control from space and introduces Meteron project experiment that will take in November this year. As part of this trial ESA astronaut Luca Parmitano will operate a rover in Netherlands while onboard ISS. We will let you know when we learn any more information about the experiment.
