• Looking for an accupack with a XH2.54 powerport, to power the RoArm-M2-Pro which is harder to find than expected.
• Details on the control-board of waveshare.
• Most accupacks have another connector system, on Conrad I could only find one pack with XH2.54 output: Pichler EgoBatt.
• A good option seems to be 6400mAh pack, although it is not clear how much Ampere can be provided, nor how it will be charged.
• Another could be this 8000mAh pack (same problem).

• In Chapter 7 reference is made to the 2014 CMU lecture notes of Statistical Techniques in Robotics, which is still given in 2022: Introduction to Robot Learning, based on Reinforcement Learning: An Introduction by Richard Sutton.
• For SfM he points to this short overview paper from 2017.
• At the end he chooses for a FloorFinding algorithm, inspired by RoboRealm.
• For navigation it used a nine-layer CNN (LeNet architecture), to learn forward, left turn, right turn.

• Chapter 6 covers NLP. The code is based on MyCroft project, which is no longer maintained (since 2022). Instead, they recomment OpenVoiceOS or NeonCore.

• Continue with Chapter 1 of Artificial Intelligence for Robotics. As good Packt book on ROS Govers recomments Effective Robotics Programming with ROS, but the accomponying github is 9 years old (and Ubuntu 16.04 based).
• The ROS2 version used in the book is ROS foxy. Used 2to3 to convert the python2 scripts of Chapter1.
• Found 30 images on roboflow called toydetector, which is clearly from Govers playroom.
• Another roboflow toydetector has 48 images, which is the one used in the book. li>The code should also run under Gazebo, as described in Arm Developer blog (ROS Kinetic). The blog uses the katana-arm.
• After installing quite a number of packages, I tried yolo task=detect mode=predict model=yolov8n.pt source="test.jpg" with as test-image the picture from Chapter 3.
• At the end of Chapter 7, Goover comes with some alternatives to Q-learning and Genetic algorithms, such as Google's SAC-X.

• The ebook A Concise Introduction to Robot Programming with ROS 2 is already on the Vital bookshelf.
• Yet, the books on the MIT bookshelf will be gone.
• Downloaded accillaries of Murphy's Introduction to AI robotica (Aug 2020).
• Waveshare also has an outdoor base with a payload of 12kg: the Cobra Flex. Strong enough to carry a robot-arm:
  
• The UGV02 has a payload of 4kg, and the robot arm is mounted off-center:
  
• There are 4 robot-arms:
  • Hugging Face's SO-ARM100 / 101 (6 DOF):
    
  • Waveshare's RoArm-M2 (4 DOF), which is suitable for various Mobile Robot Chassis (including sinking installation):
    
  • Waveshare's RoArm-M1 (5 DOF).
  • Waveshare's Robot arm for PI.
• Started with the first chapter of Artificial Intelligence for Robotics. Nice promise: 'We will be trying out several forms of AI on our journey, including supervised and unsupervised learning, reinforcement learnign, neural networks, and genetic algorithms'.
• The robot from the book has omnidirectional wheels, while the Cobra doesn't.
