Weekly Robotics #97

Issue 97

Remeber the Gundam robot from Japan (#76 and #77)? It’s moving! In other news: it’s been a while since I’ve added more than one project to Awesome Weekly Robotics from one issue and this week there are two! The most clicked last week was AR 2 & AR 3 open plan robot arms with 13.1% opens.

1) Drone Helicopter Hybrid.
YouTube
INFO: Tom Stanton is at it again. This time he has built a helicopter that instead of using traditional swashplate slows the motor down at appropriate times to achieve a ‘virtual swashplate’. If you liked this video then you have to watch the follow up on Tom’s second channel that’s way more technical and covers what Tom had tried to get to the first working prototype.

2) Building & Flying an Exercise Ball RC Plane!
YouTube
INFO: While we are on the subject of custom UAVs FliteTest had created a remotely piloted fixed wing UAV that uses an exercise ball as an (under)carriage.

3) WireViz.
GitHub
INFO: ‘WireViz is a tool for easily documenting cables, wiring harnesses and connector pinouts. It takes plain text, YAML-formatted files as input and produces beautiful graphical output (SVG, PNG, …) thanks to GraphViz. It handles automatic BOM (Bill of Materials) creation and has a lot of extra features’.

4) ‘SlothBot in the Garden’ Demonstrates Hyper-Efficient Conservation Robot.
Georgia Tech
INFO: The SlothBot that was featured in issue #44 is getting a field test! It looks like the Robotics Engineers at Georgia Institute of Technology had updated the design quite a lot - I really like that the current design comes with a head! Having “slowness” as a design principle is an interesting idea for this kind of project. Looking forward to seeing how the first demonstrator goes!

5) An Open Torque-Controlled Modular Robot Architecture for Legged Locomotion Research.
Open Dynamic Robot Initiative
INFO: Quoting the linked website: ‘This website is the entry point to the resources of the Open Dynamic Robot Initiative. This project originated in an effort to build a low cost and low complexity actuator module using brushless motors that can be used to build different types of torque controlled robots with mostly 3D printed and off-the-shelves components. This module, and extensions, can be used to build legged robots or manipulators. A paper describing the actuator module and the quadruped design can be found here’.

6) CARMA 2.
University of Manchester
INFO: Continuous Autonomous Radiometric Monitoring Assistant (CARMA) is a Jackal based platform designed for automatic radiation monitoring and is developed by Robotics for Extreme Environments Group at The University of Manchester. The robot is equipped with 2 Hokuyo LidarS, an Orbec depth camera, and two radiation probes. Here you can see a recent video showing the robot operating in a controlled environment.

7) Publication of the Week - Event Cameras: Opportunities and the Road Ahead (CVPR 2020).
YouTube
INFO: Every now and then I like to check on the progress of event cameras and every time I do I end up looking at what UZH Robotics and Perception Group (RPG) is up to. In this talk, Davide Scaramuzza shares the current state of event cameras and shows some of the research done by his group. Compared to traditional cameras these cameras output a change of brightness of every pixel, resulting in a continuous sensor feed and low power consumption (as little as 1mW!). It looks like there are already 4 companies producing these sensors and the examples shown in this talk makes some very good points. I’ll be looking forward to seeing these sensors going more mainstream.

1) Ouster OS1 - First Impressions.
msadowski.github.io
INFO: Recently I had a chance to play with Ouster OS1-16, a 16 plane automotive grade LiDAR. The above blog post describes some of the setup steps I have performed, integration with Cartographer, and workflow for extracting localized point clouds from a bag file.

Announcements

1) The FPV Drone Racing VIO Competition.
RPG
INFO: The participants are required to run their VIO algorithms on sequences selected from the public UZH-FPV Drone Racing Dataset, which include images, IMU measurements, and event-based camera data recorded with an FPV drone racing quadrotor flown aggressively by an expert pilot. The goal is to estimate the quadrotor motion as accurately as possible, utilizing any desired sensor combinations. The winning entry can win up to $2k and the deadline for submissions is September 27th, 2020.
