Weekly Robotics #327

Issue 327

The Open Source Summit in Amsterdam was a lot of fun. My next stop is ROSCon in Singapore (27-29th Oct) and Infoshare in Katowice (24-25th Nov). If you attend any of these and would like to catch up, please let me know! Next week, I'll be taking a short break from the newsletter, so see you in two weeks!

UR5 Inverse Kinematics

UR5 Inverse Kinematics cover

Alexander Elias created this fantastic write-up, which teaches you how to write an inverse kinematic solver based on IK-Geo. As you’d expect, the tutorial is making good use of maths, so make sure to load up on sugar and caffeine before doing a deep dive!

The Myth of the Planned Career

Joe Jones created another article for his Dancing with Roomba blog. This time, Joe is discussing his career path and how it has been changing over time. Sometimes travelling the world or landing a dream job does not help living a fulfilled life and you find your calling by chance.

Diffuse-CLoC: Guided Diffusion for Physics-based Character Look-ahead Control

Diffuse-CLoC: Guided Diffusion for Physics-based Character Look-ahead Control cover

There used to be a time, where every year I would go through all SIGGRAPH submissions and describe the robotic-related ones. This submission shows an interesting approach to character control that is not out of realm of possibility to be applied on robotics systems.

Building A Real Life Pixar Lamp Pt.2

Building A Real Life Pixar Lamp Pt.2 cover

A cool open-source robot arm that’s also an arm with an attached LLM. The team used the Feetech STS3215 servos, which can also be found in the SO100 project. For more information, check out the project repo.

Optimizing ROS 2 Communication for Wireless Robotic Systems

If you’ve used ROS 2 on a lossy wi-fi network, chances are you know how painful a process it can be. This paper by the Researchers from the Daegu Gyeongbuk Institute of Science and Technology presents their work on tuning DDS for this exact scenario. The output of this work is this GitHub project with a script that should help you tune your settings. If you happen to try it out, please let me know how it goes! I’m really curious how it works out.
