  • Weekly Robotics #70

    Issue 70

    Last week I’ve mentioned that I couldn’t find any video from the AlphaPilot AI drone race. Fortunately Martin Nievas had my back on twitter and shared this tweet that features a bit longer video that gives you an idea how the drone flew.

    I would like to wish a Merry Christmas / Happy Holidays to all of you reading this. If you’d like to get into christmas mood with some themed video then check out some from: ETH Zurich Autonomous Systems Lab, ETH Zurich Robotics Systems Lab, FZI Living Lab, ALTAIR Robotics Lab, Northern Robotics Laboratory, LAI Robotics, Technical University of Munich, Rozum Robotics. In hindsight I should have probably made a whole newsletter issue with these videos… Maybe next year! I bet I missed plenty of videos, feel free to share some with me on twitter and I’ll happily reshare them.

    1) Game of Drones at NeurIPS 2019: Simulation-based Drone-Racing Competition Built on AirSim.
    Microsoft
    INFO: Coming back to the topic of drone racing for a bit: “at NeurIPS the AirSim research team is working together with Stanford University and University of Zurich to further democratize drone-racing research by hosting a simulation-based competition, Game of Drones. We are hosting the competition on Microsoft AirSim, our Unreal Engine-based simulator for multirotors. The competition focuses on trajectory planning and control, computer vision, and opponent drone avoidance”. AirSim is one of the many projects I featured in awesome-WR - a database highlighting some of the interesting robotics I covered in this robotics newsletter.

    2) First Drive Test of NASA’s Mars 2020 Rover.
    YouTube
    INFO: NASA’s MARS rover was tested earlier this week. I find it fascinating how many engineers are involved in these tests. I wonder how much data a test like this generates?

    3) Aeva Unveils Lidar on a Chip.
    Spectrum IEEE
    INFO: From time to time I hear about LiDARS on chips (or solid-state LiDARS), usually without much detail. According to the article Aeva’s solution should cost <500$ when mass produced and will offer a 120° horizontal and 30° vertical field of view and a range of up to 300 meters.

    4) Digit v2: Dynamic Obstacle Avoidance.
    YouTube
    INFO: Agility Robotics engineers are invading Digit’s personal space causing it to move away. I think the captions add a lot to this video.

    5) Mimic.
    GitHub
    INFO: Mimic is an open-source Maya plugin for controlling Industrial Robots developed by Autodesk Robotics Lab. For more information see the Mimic website - it seem to have a good amount of tutorials available. If you would like to see this plugin in action then this one year old video should give you a good idea how it works.

    6) Sarcos Demonstrates Powered Exosuit That Gives Workers Super Strength.
    IEEE Spectrum
    INFO: “If you were to ask the question, What does 30 years and $300 million look like, you’re going to see it downstairs”. This IEEE Spectrum article covers Guardian XO, a 24 DoF, a full body exoskeleton allowing the user to weight up to 90 kilograms (200 pounds). I find the company’s business model interesting as they seem to offer a Robotics-as-a-service type of solution.

    7) Publication of the Week - Multi-Functional Soft-Bodied Jellyfish-Like Swimming (2019).
    Nature
    INFO: I stumbled upon this article thanks to Reddit user SDSS-J1106-1939 and his post on /r/Robotics. In this work Researchers an untethered jellyfish inspired soft robot to study jellyfish locomotion. I highly recommend watching the video showing the robot in action - when you do pay attention to the scale of these robots.

    6) ESA Commissions World’s First Space Debris Removal.
    ESA
    INFO: Clean Space initiative is kicking off, with the ClearSpace-1 planned launch in 2025. “The ClearSpace-1 mission will target the Vespa (Vega Secondary Payload Adapter) upper stage left in an approximately 800 km by 660 km altitude orbit after the second flight of ESA’s Vega launcher back in 2013. With a mass of 100 kg, the Vespa is close in size to a small satellite, while its relatively simple shape and sturdy construction make it a suitable first goal, before progressing to larger, more challenging captures by follow-up missions – eventually including multi-object capture”. The ‘chaser’ vehicle will grab the second stage using a quartet of robotics arms and then slow it down, so that both spacecrafts burn in atmosphere. For some more information about space cleaning initiatives you can see issue #4 and issue #21.

    7) Publication of the Week - KRAKsat Satellite Mission - Lessons Learned (2019).
    ResearchGate
    INFO: KRAKsat nanosatellite project aim was to test Ferrofluid Reaction Wheel as an orientation and rotation control system. The mission started on the 3rd of July 2019 and this report contains lessons learned during the mission.
