  • Weekly Robotics #47

    HeaderImage

    Last Sunday we’ve reached 1000 e-mail subscribers! This is a major milestone for Weekly Robotics and I’m really grateful for getting this far thanks to you! Starting in 2 weeks (after issue #49) I’ll be heading out for a 3 week holiday, therefore Weekly Robotics will enter ‘minimum support mode’. You will still get your weekly dose of interesting robotics news and projects but with minimal redaction. And if you happen to be in Norway and want to meet and talk robotics, feel free to contact me. Coffee is on me!

    1) Reinforce Your 3D Prints with Steel.
    YouTube
    INFO: This video by Brauns CNC explores a technique of reinforcing 3D prints with steel wire. After reinforcement the author performs a destructive tensile testing on 3 types of barts that were printed in pure plastic and reinforced with steel and observing an increase in strength in the range of 55.6% to 107.5%.

    2) Jumping Space Robot ‘Flies’ Like a Spacecraft.
    ESA
    INFO: If you need to move around low gravity environment such as moon, why not try jumping? SpaceBok is the quadruped robot designed by a Swiss student team from ETH Zurich and Zhaw Zurich. The robot is using dynamic walking that allows gaits with full flight phases to get around low gravity environments. The robot is using a reaction wheel to stabilize itself in the air (you can see it in action in the video featured in the article). I really liked the test setup with a free floating platform and the robot mounted sideways to it!

    3) Robot-ants that Can Jump, Communicate and Work Together.
    EPFL
    INFO: Researchers at EPFL Professor Jamie Paik’s Laboratory had created tiny robots that weigh only 10 grams and are based on PCBs that can be folded to form a 3D shape of the robot and can accommodate all the robot components. The robots can move using shape-memory alloy actuators. For more information about the folding robots you might want to check out this TED talk in which Jamie paik talks about the robots her group is working on (origami haptic feedback devices look interesting).

    4) ROS 2 Command Line Interface.
    Ubuntu
    INFO: This short post by Jeremie Deray goes into how the command line interface tools had changed between ROS and ROS2 and specifies some of the ones that were freshly contributed by Ubuntu engineers.

    5) OpenPnP - Open Source SMT Pick and Place System.
    OpenPnP
    INFO: OpenPnp is a ready to run software for pick and place machines. The software supports various designs and is in active development. I found this project on YouTube utilizing OpenPnP very satisfactory to watch.

    6) Developing Semi-automatic Nuclear Decommissioning Robots.
    Lancaster University
    INFO: Engineers from Lancaster University are building a semi-autonomous robot for handling nuclear waste. The robot is a mobile platform with two manipulators capable of grasping and cutting metal parts. The semi-autonomy of the robot allows the operator to select parts the robot should perform tasks on. For more information about the system you can check the Open Access publication about it.

    7) Publication of the Week - Dragonfly: A Rotorcraft Lander Concept for Scientific Exploration at Titan (2018).
    jhuapl.edu
    INFO: As promised in the previous issue here is a publication that introduces Dragonfly multirotor destined for Titan. Interestingly the first aircraft suggested for similar mission was a helicopter, however the idea was dropped due to the mechanical complexity of single rotor aircrafts. Even though the aircraft would perform just fine in a 4-rotor setup the 80rotor in coaxial configuration was chosen for redundancy. I really enjoyed the insights about the energy required to send science data to earth: “Missions with high-gain antennas (HGAs) empiri-cally require about 5 mJ per bit per astronomical unit”.

    1) Humble Book Bundle: Programmable Boards by Make Community.
    HumbleBundle
    INFO: In this Humble Book Bundle you can grab various books related to single board computers, microcontrollers, sensors and even FPGAs. If you purchase this bundle through the above affiliated link you can choose to support Weekly Robotics.

The official goal of RoboCup project is: “By the middle of the 21st century, a team of fully autonomous humanoid robot soccer players shall win a soccer game, complying with the official rules of FIFA, against the winner of the most recent World Cup”. Although the event is most likely finished now you can still view the official livestreams and as pointed out by Lutz the streams provided by Nao Devils seem to be particularly good.

    3) ‘Boaty McBoatface’ shows promising future of AUVs.
    The Robot Report
    INFO: Boaty McBoatface (if you’ve missed the origin of it’s name then Wikipedia has you covered) traversed more than 180 km (112 mi) autonomously at depths of up to 4 km (2.5 mi). During the mission Boaty measured the temperature, saltiness and turbulence of the water at the bottom of the ocean in order to map better the effects of global warming on the rise of sea levels. You can read about the mission on the University of Southampton website. We also recommend reading the article on Robot Report as it gives quite a nice overview of the Autonomous Underwater Vehicle market.

    4) Px4 Developers Summit Presentations.
    YouTube
    INFO: The above YouTube playlist contains the presentations from Px4 (an open source flight control software) that took place on June 20-21st in Zurich, Switzerland.

    5) First-ever Successful Mind-controlled Robotic Arm Without Brain Implants.
    ScienceDaily
    INFO: Researchers from Carnegie Mellon University managed to use a non-invasive brain-computer interface (BCI) to allow humans to make a robot arm follow a cursor on a screen. The team plans to conduct clinical trials in the near future. You can see the video of the robot in action on YouTube.

    6) Study: Social Robots Can Benefit Hospitalized Children.
    MIT
    INFO: Researchers from MIT Media Lab, Boston Children’s Hospital and Northeastern University did a study on the effects of using Huggable, an animatronic teddy bear with hospitalized children. During the trials the robot was remotely operated by a specialist that could move Huggable’s body actions, gaze and facial expressions as well as speak to the microphone to have their voice transformed into the bear’s voice. In the future the researchers hope to make the robot autonomous.

    7) Cutting the Power Cord For the First Untethered Flight.
    Wyss Institute
    Robobee, a 259 miligram flapping wing robot that uses 120 miliwatts of power, performed the first untethered flight. The robot is currently powered with solar cells (each weighting 10 mg).

    8) Publication of the Week - Engineering a Safer World: Systems Thinking Applied to Safety (2011).
    MIT Press
    INFO: This Open Access book by Nancy G. Leveson is offers a view on new approaches to safety engineering. The book contains many examples of safety failures and although I still didn’t finish it I can highly recommend it. Since the book is open access you can download it as a PDF or buy it from any source listed on the site.

    Big thanks to Lutz for sending us the information about RoboCup! If you know of something that we should cover then feel free to contact Mat.

    1) ROS Web Tutorial Part 2 - Working With Cameras.

  • Weekly Robotics Q2 2019 report

    Summer is here! And, wow, we can really feel it in central Europe.

    I decided to start doing quarterly updates with the newsletter statistics and future plans starting now! I hope that you will enjoy reading this report as much as I enjoyed making it.

    Email Subscribers

    We ended this quarter with 978 email subscribers (I was really hoping to reach 1k subscribers for this update, but you can’t always get what you want). Here is how the number of subscribers changed since the beginning of the newsletter:

    Mailchimp growth

    Weekly Robotics started this quarter with 664 email subscribers, meaning that we observed a 47% growth in subscribers in the past 3 months. I hope we can keep up this rate of growth for the foreseeable future.

    Website Traffic

    One of the goals I set for the Weekly Robotics was to make every issue of the newsletter available online and easily accessible to everyone, even if they are not subscribed via email. In some weeks I saw quite a big spikes in the number of users visiting the site, even though I kept using the same channels for sharing the information about the new issues and we didn’t run any ad campaigns just yet.

    Website visits

    According to Google Analytics we had 6.8k users and 9.3 sessions in the last quarter, increasing the traffic by 125% compared to the last quarter.

    Time Spent on the Newsletter

    This quarter I started logging time spent on the Newsletter. This includes all the research for every issue, development of tools, writing reports etc. Basically I logged every minute spent on the work related to the newsletter and the total time I spent these months came to 80:49:36 and there was only one week in which I spent under 4 hours working on Weekly Robotics:

    Time spent on Weekly Robotics

    Upgrades and future plans

    There are 3 things we improved in the quarter and a day:

    • Introducing the announcement section in WR #32 (the last day of Q1!)
    • Adding header image starting with WR #37 (5th of May)
    • Creating Awesome Weekly Robotics database and hosting it on WR and GitHub (9th of June)

    The plan for Q3 2019

    There is a single goal for me for Q3: to automate the newsletter workflow and look into self-hosted email delivery platform.

    Long Term Goals

    Here are some of the long term goals that I’m hoping to achieve this calendar year with Weekly Robotics:

    • Website redesign - especially looking into the structure of the website menu and maybe adding a landing page (while keeping the newsletter archive intact)
    • Finding the first sponsor/contributor for the newsletter
    • Starting a discussion group - either some kind of forum or a Slack channel

    Thanks a lot for being part of Weekly Robotics. I hope that you continue enjoying this newsletter! If you have any thoughts on this report don’t hesitate to reach out.

    We are working on delivering some data for you. Next week we plan to share a Q2 2019 report! The numbers are already quite interesting, hope you are looking towards them as much as Mat is! In the meantime we are starting a call for header images, go to Announcements section for more information.

    1) PyRobot - an Open Source Robotics Research Platform.
    PyRobot
    INFO: PyRobot is an open source package for benchmarking and running experiments in robot learning that is developed by Facebook. According to the documentation the goal of this project is to abstract away the low-level controls of robots from high-level motion generation. Currently the package supports two robot platforms: LoCoBot and Sawyer. If you would like a longer read about PyRobot then you should check out this publication on arXiv.

    2) GSoC 2019: Integration of ArduPilot and VIO Tracking Camera for GPS-less Localization and Navigation.
    ArduPilot Forum
    INFO: As part of Google Summer of Code 2019 Thien Nguyen has developed multiple tutorials on interfacing Intel Realsense T265 tracking camera with ArduPilot. Currently there are 5 Labs available. You will find links to them in the above post.

    3) HoverBot.
    GitHub
    INFO: HoverBot is a self-balancing robot platform built with ODrive, hoverboard hub motors, Bosch BNO055 IMU and Arduino Mega. The project repository contains high quality information about the project, build instructions and some videos. If you like the self balancing robots then you might find this smaller robot that we covered in issue #39 interesting.

    4) Robotic Roadworks and Excavation System.
    YouTube
    INFO: The above video shows a roadwork and excavation system developed by ULC Robotics with collaboration from SGN. The robot is tracked and is carrying what seems to be an ABB IRB series robot manipulator. According to the information in the video the system is capable of performing below-ground sensing, road surface cutting and excavation.

    5) Inside Anki Shutdown: Who Owns IP, Assets Auction, Failed Partnership.
    The Robot Report
    INFO: This article from The Robot Report tells you why you shouldn’t get your hopes up about Anki coming up. We were quite sad looking through the pictures in the auctioned office listing and also surprised to find a Jibo robot being part of the auction.

    6) T-RHex Is a Hexapod Robot With Microspines on Its Feet.
    IEEE
    INFO: A student’s team called Team ScienceParrot from Carnegie Mellon University made an upgrade to RHex robot by fitting it with a tail and microspines. The microspines allow the robot to get a strong grip on surfaces such as bricks, wood and concrete. According to the article the highest angle of the wall the robot can climb is 55 degrees (but it can hang onto a wall with an angle of 135 degrees!).

    7) Publication of the Week - How Robots Change the World (2019).
    Oxford Economics
    INFO: We’ve read this publication (to get a full access to it you will need to request it via e-mail form on the website). The report talks about the growth of robotics (especially between 2010 and 2019) and how the increased adoption of Robotics can affect the GDP of some of the countries and regions and at the same time how it can cause job displacements.

    1) ROS Web Tutorial Part 1 - Rosbridge Server and Roslibjs.
    msadowski.github.io
    INFO: In this beginner’s tutorial Mat shows how to create a simple webpage that integrates with ROS through rosbridge and that uses a virtual joystick to send velocity commands to the robot.
