  • Weekly Robotics #56

    Issue 56

    As I’m writing this newsletter I’m at EPFL Open Days 2019 in Lausanne, Switzerland. It was quite cool to see some of the projects researchers work on at EPFL and in other Swiss organizations. Finally I was able to see ANYmal in action live! In other news every now and then I update the awesome weekly robotics list and as I’m writing this issue the list has over 70 entries!

    1) Meet The 20 Finalists In The 2019 Hackaday Prize.
    Hackaday
    INFO: Hackaday announced 20 finalists of the Hackaday Prize. Among them we can find projects related to robotics such as 3D printed prosthesis with CV, BCI and EMG, Bobble-Bot (WR #38), SmallKat, Axiom: 100+kW Motor Controller and Blackbird Bipedal Robot. I can also see myself using OPEN Power at some point in the future if they ever start selling those.

    2) Slam Toolbox.
    GitHub
    INFO: slam_toolbox is a ROS package for 2D lifelong mapping and localization in potentially massive maps developed by Steve Macenski. I started setting it up this week with Robosynthesis and if you are doing SLAM with ROS I highly recommend checking it out. My experience so far is that if you have a odom->base_link transform and a semi decent LiDAR then this package can work very well pretty much out of the box.

    3) EU Long-term Dataset with Multiple Sensors for Autonomous Driving.
    epan-utbm.github.io
    INFO: Engineers from Université De Technologie De Belfort-Montbéliard released a number of datasets containing data from various sensors mounted on a car. Among the sensors used we can find 2 stereo cameras, 3 lidars, radar, GNSS receiver with RTK base station, IMU and 2 RGB cameras. The datasets are provided in the form of ROS bagfiles.

    4) Russia Terminates Robot Fedor After Space Odyssey.
    Phys.org
    INFO: Skybot F-850 (featured in issues #53 and #54) completed his mission and according to the article it won’t be coming back to the ISS any time soon. Apparently using legs in space is no easy feat!

    5) Water Jet Powered Drone Takes Off With Explosions.
    IEEE Spectrum
    INFO: Researchers from Aerial Robotics Lab at Imperial College London had developed a ‘fying fish’ fixed-wing UAV that is propelled by gas explosions. The gas is created from the reaction of calcium carbide with water (you can see some experiments on that on YouTube) and when ignited the water forced out of the combustion chamber generates 51 N of thrust, launching the robot as high as 21 meters up. You can see the drone in action in this video.

    6) This Adorable Baby T-Rex AI Learned To Dribble.
    YouTube
    INFO: This video from Two Minute Papers shows using AI to compose complex motions from the sum of elementary movements. Even though this paper demonstrates the solution for 3D animations, I can see how it could be utilized on robots with complex kinematic chains. Big thanks to Artur for the tip about this video!

    7) Publication of the Week - ShapeBots: Shape-changing Swarm Robots (2019).
    arXiv
    INFO: Each ShapeBot is equipped with 2.5 cm thin reel-based linear actuator that can extend to 20 cm (~7.9 in) both horizontally and vertically The work presented in the paper is the result of collaboration between the University of Colorado Boulder and the University of Tokyo. The robots are relatively simple with ESP8266 microcontroller used as the brains of the robot and BOM summing up to 20-25 USD. I found the ShapeBots simulator to be very satisfying to experiment with and nicely showing the concept of these robots being used in a swarm setting. You can find the video showcasing the bots in action on YouTube.

    Careers

    1) Parkopedia (London, UK) - Robotics Software Engineer.
    INFO: Parkopedia was founded with the mission of being able to answer any parking question, anywhere in the world.

    Announcements

    1) The Space Robotics Challenge Phase 2.
    Nine Sights
    INFO: As NASA moves forward with plans to support human exploration of the solar system, a critical need arises to supply basic materials such as oxygen (O2) and water (H2O), food, propellants, and other materials (radiation shielding, clothing, etc.). As mankind ventures farther from Earth and for greater periods of time, it becomes imperative to develop technologies and mission architectures that utilize local resources, such as those found in lunar regolith, to provide supplies needed for human exploration. The objective of SRC Phase 2 is to find solutions to allow a heterogeneous, multi-robot team to autonomously complete tasks envisioned for a lunar in-situ resource utilization (ISRU) mission. This challenge will require competitors to develop software that allows a virtual team of robotic systems (i.e. virtual robotic team) to operate autonomously to successfully achieve these tasks. The application deadline is the 20th of December this year.

  • Weekly Robotics #55

    Issue 55

    Reading an article on 15 years of Hackaday made me realize just how quickly technology is advancing these days. 15 years is just a half of my life and around half life ago my computer was still running a 351 MHz Pentium II processor. Thinking that right now I can get a Raspberry Pi Zero that is smaller than a business card and has 1 GHz processor is simply unbelievable. As cheesy as it sounds, we live in the future.

    1) A Car Phone — No, Not That Kind.
    Hackaday
    INFO: Deeprc is a project by Piotr Sokólski that can be considered a google cardboard for RC cars. The brain of the device is the phone that fits in the chassis and connects to the steering servo and a brushless motor. A mirror angled at 45 degrees allows to use the phone camera as a vision sensor. You can learn more about DeepRC Robot Car on the project page.

    2) XIVO: X Inertial-aided Visual Odometry and Sparse Mapping.
    GitHub
    INFO: XIVO is a library for visual-inertial odometry/mapping developed by UCLA researchers. The library can work either as a standalone project or it can be used with ROS. Currently the licence allows to use it for academic/research purposes, however a commercial licence is available.

    3) The Robot Ship Set to Cross the Atlantic and Change the World.
    Daily Beast
    INFO: This article covers Maxlimer, an unmanned surface vehicle developed by SEA-KIT. The vessel can autonomously deliver up to 2.5 tonnes of cargo. We need to point out that the article mentions that the Maxlimer is posed to become the first unmanned surface vessel to cross the Atlantic. As far as I know this feat was already accomplished by Sailbuoy and Saildrone.

    4) A Gentle Grip on Gelatinous Creatures.
    The Harvard Gazette
    INFO: The researchers had created grippers capable of safely capturing some of the most delicate animals on the planet. “The gripper’s six “fingers” are composed of thin, flat strips of silicone with a hollow channel inside bonded to a layer of flexible but stiffer polymer nanofibers. The fingers are attached to a rectangular, 3D-printed plastic “palm” and, when their channels are filled with water, curl in the direction of the nanofiber-coated side. Each finger exerts an extremely low amount of pressure — about 0.0455 kPA.”

    5) Drone Crowdfunding Status Updated.
    Google Docs
    INFO: Charles Blouin on DIY Drones forum updated an original spreadsheets by Chris Anderson that lists some of the crowdsourced Drone projects and their status. It’s interesting to see how many of these projects are delayed but still seemingly active. Hope the companies can deliver!

    6) Reach Robotics Shuts Down Consumer Robotics Business.
    The Robot Report
    INFO: Reach Robotics, that sold consumer entertainment hexapod robots shut down earlier this week. This is yet another proof that doing consumer robotics is difficult.

    7) Publication of the Week - ASSURE UAS Ground Collision Severity Evaluation Final Report 2017-2019.
    assureuas.org
    INFO: This document is an 830 pages collection of reports developed by the ASSURE team. “The goal for this team was to assess injury potential of various SUAS of different material properties and construction. The team conducted fixed wing and multirotor SUAS failure flight testing and aerodynamic modeling, full anthropomorphic test device (ATD) impact testing, simplified head and neck only ATD impact testing, ATD and human‐body model impact simulations, Post Mortem Human Surrogate (PMHS) impact testing, and high-fidelity head and neck only impact simulations. During this project, researchers collected data on over 41 flight test points, 155 simplified impact tests, 133 ATD impact tests, 41 PMHS impact tests, over 100 full-ATD and human-body model impact simulations, and 15 high-fidelity head and neck simulations. Tests were conducted with 16 different multi-rotor and fixed-wing SUAS and objects (payloads, wood blocks and batteries) with weights ranging from 0.75 - 13.2 lbs”.
