Chaz
Chaz discussed:
'The Open Source Robotics Corporation, the for-profit company behind Open Robotics' Robot Operating System (ROS), has announced its acquisition by Alphabet subsidiary Intrinsic' -- hackster.io
https://www.hackster.io/news/intrinsic-buys-open-robotics-commercial-arm-but-leaves-ros-and-gazebo-with-the-foundation-98db7ed2ddbf
This separates the commercial arm from the non-profit arm which will retain ROS, Gazebo, and Open-RMF.
Chaz feels that this move is beneficial as Intrinsic can apply a lot of resources to feed back into projects like Gazebo, which he feels needs some improvement.
Chaz also covered 'Robotics Transformer 1 (RT-1)' of which Google is a part:
'RT-1’s architecture: The model takes a text instruction and set of images as inputs, encodes them as tokens via a pre-trained FiLM EfficientNet model and compresses them via TokenLearner. These are then fed into the Transformer, which outputs action tokens.' -- Google Research

To wrap things up, Chaz hopes to present at a future meeting a ROS 2 demonstration as installed on his Linux box. This should prove to be quite exciting as few of us have seen ROS 2 in the wild!

Mike Soniat
Mike turned his Facial Recognition prowess towards the Zoom screen.
At the last meeting, he took a screenshot of the attendees and clipped out portraits for use in training his AI model.
This time around, he fed the current Zoom screen in to the model...and voila...it recognized everyone it should...and flagged as unknown those for which it had no training.
John did some on-the-fly testing by holding a phone displaying his image up to his camera...and that was recognized as well!

Once again, Mike is only using a single image of each person for training.

Spud, Soniat, and the Skoonies are going to meet up in Houston at the Ion soon and work on transferring this capability to Spud the Bot.

Hunter Schoonover
Hunter received the first batch of his AFE board from JLCPCB. It will be assembled over the next week. He is working on a test board with a Teensy 4.1 to be used in debugging.
Hunter also discussed Simplify3D's newly reversed version V5. Simplify3D is a commercial 3D printing slicer which he uses extensively. It looks like there are a lot of new features and we can expect to see some examples soon!
See the header photo for a pic of the board!

Spud
Spud is even more excited about ChatGPT...if that's possible!
One tester asked ChatGPT about a paper that the tester had written. ChatGPT wrongly informed him that he had authored no such paper. The tester told ChatGPT that it was wrong, and ChatGPT asked for evidence. The tester provided a link to such evidence and ChatGPT refused to verify or counter the info thereafter.
The assumption is that ChatGPT will eventually absorb the new info. The main point here is that it added new information during the conversation and incorporated that info into subsequent conversation.
Spud's Jetson Nano has been updated with the latest image from NVIDIA in preparation to begin using OpenCV face detection and recognition, following the lead of Mike Soniat.
This will only hurt a little bit...(see header photo)

Mike Schoonover offered the following Linux tip:
Add a file named .inputrc to your home directory with the following contents:
"\e[A":history-search-backward
"\e[B":history-search-forward
Close the command window and reopen.
Afterwards, you can type part of a command, such as 'python' and then the Up arrow and it will bring up the previous time you used that command...even if it was far back in history.
Using the Down arrow will search forwards in history.
This is a lifesaver!
Many times you will want to rerun a complex command which you executed many commands ago. Without this trick, you had to press the Up key many times to find that command. Now you can skip all those other commands.
