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.

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: I found this paper through this article from the University of Cambridge. The system developed consists of an UR10 robot arm with custom end-effector, two cameras and a non-actuated mobile platform. The system is controlled using ROS and is using two convolutional neural networks (CNN): one for lettuce localization and the other for lettuce classification. I especially liked the notes about moving the system from the lab to the field and noticing a calibration is needed (it was achieved using Aruco markers). The average cycle time achieved by the team during trials was 31.7s, mainly due to the end-effector weight of 8 kg.

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.
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.
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.
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.
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.
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.
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).
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”.
