Weekly Robotics Newsletter Archive [7/23]

  • Weekly Robotics #63

    Issue 63

    I work on this newsletter in phases. Phase 1 is going through my news feed and shortlisting the articles I found interesting (currently I use bookmarks for that). The second phase is going through the shortlisted webpages and selecting the ones that will appear in the next issue. This week I broke the record with 38 webpages shortlisted (!). The third phase is selecting the 7 top features. If a page doesn’t make it to the top I either add it to the next issue or I delete it. I was thinking that in the future I might add the links that ‘did not make it’ to the newsletter.

    1) Saildrone USV Completes First Atlantic Crossing East to West.
    Saildrone
    INFO: I’ve covered the first Atlantic crossing by Saildrone in the issue #28. This time Saildrone was the first Unmanned Surface Vehicle to pass the Atlantic East to West and thus becoming the first unmanned vessel to make a roundtrip of the Atlantic (it traveled the first leg of the journey in August this year).

    4) Can Autonomous Wheels Disrupt Indoor Mobility?
    The Robot Report
    INFO: In this article Olivier Mitchell introduces wheel.me, an Oslo based company working on autonomous wheels (they were hirigin back in May). I really like the idea and I can’t wait to see this technology applied somewhere. Apart from technology the curious thing I found about this article is the wheel.me business model, which is described as indoor-mobility-as-a-service. I’m really curious to see how Robots-as-a-service evolves in the future. Will try to keep you posted!

    5) Helping Autonomous Vehicles See around Corners.
    MIT
    INFO: MIT Researchers are working on a camera that uses computer vision techniques to detect and classify changes of shadows on the ground.

    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.

    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.

    2) Drones as Detectives: Surveying Crime Scenes for Evidence.
    IEEE Spectrum
    INFO: I’ve heard of a similar idea years ago in the context of using drones and photogrammetry for accident mapping (this article from PhotoModeler Technologies will give you an idea what I’m talking about). I’m not sure how useful drones would be on the crime scenes though given that a person can easily take photographs from multiple angles with a handheld camera.

    3) Xaxxon OpenLIDAR Sensor.
    Xaxxon
    INFO: This project is an open source lidar built using Garmin’s Lidar-Lite v3 distance sensor. The maximum range of the assembled LiDAR is 40 meters and it can rotate at 250 RPM (equal to 4.17 Hz full scan rate).

    4) Walmart’s Robot Army Has Arrived.
    Fast Company
    INFO: How to integrate robots into places full of people while signaling robot’s intent? That is one of the problems Bossa Nova has to tackle. I found this article to be a good inspiration to think about user interaction in Robotics.

    5) TRI Teaching Robots to Help People in their Homes.
    Toyota Research Institute
    INFO: I really like the design of this robot - a body of a humanoid robot torso attached to a robot manipulator that is rigidly connected to a mobile robot platform. I recommend watching this YouTube video about this R&D Project. Given that TRI is in the ROS2 Technical Steering Committee what are the chances of this platform running ROS2?
