Weekly Robotics Newsletter Archive [2/15]
It’s our birthday! I started this project one year ago to organize the projects I was learning about and to spread interesting projects and articles. During this year I not only learned a lot about robotics and some fascinating projects but also about persistence and building habits. I hope that you too, dear readers, had learned something from some of the issues published so far. Finally, big thanks to Artur and Zack for sending me some of the articles that are featured in this issue.
2) Lights-out Pharma Factory: Why the Future of Pharma Production is Robotic.
INFO: Big thanks to Zack from Multiply Labs for forwarding me this article. The article is an interesting take on how Multiply Labs is using Robotics for creating personalized pharmaceutical prescriptions at scale. I highly recommend looking at the video embedded in the article showing Multiply Labs process.
3) Ball Balancing PID System.
INFO: This tutorial by Johan Link shows the steps to create a parallel platform capable of balancing a ping-pong ball. The system uses 3 servos, a camera, a custom PCB for servo control and custom software written in Python.
4) Suit up With a Robot to Walk AND Run More Easily.
INFO: Researchers had developed a lightweight exosuit assisting with gait-specific hip extension during both walking and running. The exosuits assists the wearer through a cable actuation system between the waist belt and thigh wraps. Weighing 5 kg the system is said to be able to reduce the metabolic cost of walking by 9.3% and running by 4%.
5) Disney Research Makes Dynamic Robots Less Wiggly, More Lifelike.
INFO: This article forwarded to me by Artur describes the work done by Disney research for retargeting animations onto lightweight physical robot characters while suppressing unwanted vibrations by using customized motor profiles. The video featured in the article is well worth a watch and if you would like to explore this topic further then the published paper is a great way to start.
6) A Miniature Stretchable Pump for the Next Generation of Soft Robots.
INFO: Scientists at EPFL had developed a miniature stretchable pump that can be used for soft robotics applications. Via linked article: “The pump has a tube-shaped channel, 1 mm in diameter, inside of which rows of electrodes are printed. The pump is filled with a dielectric liquid. When a voltage is applied, electrons jump from the electrodes to the liquid, giving some of the molecules an electrical charge. These molecules are subsequently attracted to other electrodes, pulling along the rest of the fluid through the tube with them.”
7) Publication of the Week - Soldered Electrical Connection: NASA Technical Standard (1997).
INFO: Have you ever wondered how NASA does its soldering for space flight hardware and mission critical ground support equipment? I didn’t until I came across this document in one of the issues of The Prepared. I found the standard to be quite exhaustive and full of good advice. If I ever need to set up a proper working station I’ll be heavily consulting it.
Being on holidays I don’t read as many articles as I normally would, still I found some time to read “All the best engineering advice I stole from non-technical people” by Marianne Bellotti and found it to be very insightful and a very good read. Next week’s issue of WR will be the last of my holiday edition, after which you can expect to see some improvements to this project.
1) Robots Can Play Key Roles in Repairing our Infrastructure.
The Robot Report
INFO: This Robot Report article from June is a great introduction on using robots for pipe inspection and maintenance.
2) How to Design For CNC Milling.
INFO: In this post Adam Bender gives quite useful advice on 3D part design for CNC milling. It’s interesting how a badly designed part can almost double the price of an element.
3) Spring-Loaded Drone Collapses Mid-Flight to Zip Through Windows.
INFO: UC Berkeley researchers created a spring loaded drone. The arms of this robot are spring loaded causing them to fold whenever the motor-propeller combination is not producing any thrust. If you are into drones then the video included in the article is quite worth a watch.
4) ROSCon 2019 Program is Out.
INFO: The program for ROSCon 2019 that will take place from 31st of October to 1st of November is out! Unsurprisingly, there is a lot of focus on ROS2 related presentations and I’m expecting to learn a ton! As soon as there is some information about livestream published I’ll let you know!
5) Underwater Drones Nearly Triple Data From the Ocean Floor.
INFO: From this Bloomberg article we can learn about Ocean Infinity, their seabed mapping business and successful shipwreck discoveries. All powered by Kongsberg Maritime AS submarines costing anywhere from $5-$10M.
6) Using a ‘Cave Rover,’ NASA Learns to Search for Life Underground.
INFO: BRAILLE (Biologic and Resource Analog Investigations in Low Light Environments) is a NASA’s project looking into detecting life on the walls of volcanic caves from afar. For this purpose NASA engineers are using the CaveR rover equipped with DSLR cameras and Velodyne LiDAR to perform its tasks.
7) Publication of the Week - Expecting the Unexpected - Radiation Hardened Software (PDF).
INFO: This week let’s learn about Single Event Upsets (SEUs) or bit-flips. Bit-flips can occur when a cosmic ray or other source of radiation hits a memory die and causes a single bit to change state from 0 to 1 or vice versa. The reason I thought it would be interesting to cover this topic was this article from The Register that tells us about an issue in Boeing 737 Max architecture where bit-flips can cause pilots to lose control of the aircraft. From the linked paper we can learn about the conventional and software based approaches for handling software in places where radiation is a concern. The core of the paper is about The Radiation Hardened Software Project (RHS), a software library that is resilient against probabilistic errors and handles error detection, recovery and reconfiguration (I quite like the idea of using checkpoints in software). If you like podcasts then Radiolab has an excellent episode on bit-flips that focuses on voting machines and cars.
1) The FPV Drone Racing VIO Competition.
INFO: University of Zurich Robot Perception Group is organizing an FPV Drone Racing Visual Inertial Odometry competition. The participants will work with UZH-FPV Drone Racing Dataset (you might know it from the awesome weekly robotics list) with the goal of estimating the drone position as well as possible. The author of the best solution will win $1,000 and a chance to present their approach at the IROS 2019 Workshop “Challenges in Vision-based Drone Navigation”. The deadline to submit estimated trajectories is 1st of October 2019.
I’m sending out this issue from a picturesque Norwegian island Andøya, where 5 years ago at Andøya Space Center I took part in sounding rocket campaign. That campaign is probably one of the reason why you are reading so much about space robots in this newsletter!
1) ROS Sensor Fusion Tutorial.
INFO: This 2 part tutorial by methylDragon covers all the basics on doing sensor fusion in ROS using the robot_localization package, AMCL and Marvelmind Robotics beacons.
2) Swiss Post Suspends Drone Delivery Service After Second Crash.
INFO: Back in January the first Swiss Post delivery drone made by Matternet suffered a short circuit that interrupted GPS and caused the drone to parachute into Lake Zurich. Back in May, one of the drones suffered another failure but this time the parachute tether was severed by the sharp elements of the drone causing the 10 kg drone to crash uncontrollably, prompting Swiss Post to suspend any further tests until all issues are resolved.
3) 15 European Robotics Startups to Watch.
The Robot Report
INFO: This post in The Robot Report showcases 15 EU startups chosen by The Robot Union (we are proud to be their community partner!) in their second project call. I think it’s a very interesting set of companies to check out and follow.
4) Meet Aquanaut, the Underwater Transformer.
INFO: Houston Mechatronics Inc. had created Aquanaut - an interesting underwater submarine that can transform itself into a half-humanoid robot. From the article and the linked video it looks like a solid piece of engineering that I recommend to go through, especially if you are interested in underwater robots.
5) 3D-Printable Robot With Mecanum Wheels.
INFO: Teukkaniikka is working on a 3D printed mobile robot with mecanum wheels. Some of the files are already available on Thingiverse. If you find the project interesting please consider supporting the author on Patreon.
6) Meet the Robots Toyota is Bringing to the 2020 Tokyo Olympic Games.
INFO: This article presents 5 robots that Toyota prepared for the 2020 Olympic Games. When we watch the Olympic Games are we going to cheer for the athletes or the fetching robots? Time will tell and I’ll be here to cover it!
7) Publication of the Week - An Information Model for Modular Robots: the Hardware Robot Information Model (HRIM) (2018).
INFO: In memory of Acutronic Robotics let’s revisit the HRIM paper that I featured in Weekly Robotics #7. The thing I liked about HRIM was the promise of Plug’n’Play hardware that can be seamlessly integrated into robots. I hope that we will be able to build something on top of the foundations provided by Acutronic Robotics.
8) H+ Weekly.
INFO: H+ Weekly is a weekly newsletter about new technologies (AI, transhumanism and robotics) that takes a more pop-sci angle than Weekly Robotics. I’ve been subscribed to H+ for couple of months now and can fully recommend it!

This week in the newsletter we feature a header image from Bossa Nova Robotics. If you would like to work on retail robots then you will find some more information about them in the careers section. Since yesterday I’m on holidays and since I’ll be spending most of my time in the wilderness and hiking I won’t be able to dedicate the usual amount of time to the project. It’s quite likely that some of the readers will take over the Publication of the week part of the newsletter for the next 3 weeks. Stay tuned!
1) Acutronic Robotics Closes After Financing Plans Fall Through.
INFO: Sad news from Spain. Acutronic Robotics, a company behind ROS2 ready MARA arms and H-ROS will be closing its doors at the end of July. The reason cited in the above blog post are issues with financing and acquisitions. Acutronic Robotics was also part of the Ofera Consortium working on micro-ROS project that I was really looking forward to see grow.
2) Mauled by Lions, Trampled by Elephants, Stolen by Cubs: 10 Years of Adventures with BeetleCam.
INFO: Happy Birthday! Earlier this month BeetleCam turned 10. In this video Will Burrard-Lucas shares some of the stories about this mobile robot platform. I found the video to be quite entertaining and the stories captivating. The video also features many of the wildlife photos taken throughout the years.
3) Cable Robot.
INFO: I really liked this cable robot by Tom from Hackaday. The robot is running G-code (similarly to 3D printers or milling machines) and has 3 cable hoists actuators controlled by EMC2 software.
4) Lyft Level 5 Autonomous Vehicle Dataset.
INFO: Lyft is providing access to their Level 5 autonomous driving dataset. The dataset contains raw sensor camera and LiDAR inputs, human-labelled 3D bounding boxes of traffic agents and underlying spatial semantic map. Each vehicle was equipped with: 3 LiDARs (one on the roof and 2 on the bumper, all firing at the same direction at any time), 6 wide field of view cameras covering 360 FOV around the car, one long focal length camera pointing up. On the linked website you can find a dataset sample that you can play in your browser.
5) Automated System Generates Robotic Parts for Novel Tasks.
INFO: MIT researchers created a system for fabricating actuators to an enormous number of specifications. An example of the developed actuator is a portrait of Vincent Van Gogh when actuator is laid flat but when titled and activated it shows “The Scream” painting by Edvard Munch. The actuators are made of 3 different materials with various properties (colours, flexibility, magnetization). The software developed by the researchers breaks down the design into millions of voxels and then performs millions of simulations to achieve the specification.
6) LightSail 2 Successfully Deploys Solar Sail.
The Planetary Society
INFO: LightSail is a crowdsourced project (I really recommend the Kickstarter video featuring Bill Nye) that is aiming to prove that a cubesat can use a 32 square meters sail as a propulsion method. The satellite is expected to keep rising the orbit for one month. It is also expected to reenter the atmosphere in about 1 year. I also recommend having a peek at the mission control.
7) Publication of the Week - ROS Navigation Tuning Guide (2016).
INFO: This guide by Kaiyu Zheng is a useful resource for tuning a wheeled robot navigation using move_base package in ROS. The guide offers a good practical approach to tuning the platform parameters, global and local planners, costmap and robot localization with AMCL.
1) Airbus, Project Vahana (Santa Clara, CA, US) - Flight Controls and Dynamics Engineer.
