How do I generate /odom from BLDC hub motor hall sensors?(reddit.com)
I'm building an autonomous rover using ROS2. For mapping, I'm using SLAM Toolbox, and my goal is to navigate the rover autonomously. My rover uses BLDC hub motors (the type of wheel in the picture) that have built-in hall sensors. However, I'm confused about how to generate the /odom topic required by SLAM Toolbox using these hall sensors. From what I understand, SLAM Toolbox needs odometry data, but I'm not sure: How to convert hall sensor readings into wheel odometry. How to calculate wheel position, velocity, and robot pose from the hall sensor data. Whether hall sensors alone are accurate enough for odometry. If there are any ROS2 packages or existing solutions that can help with this. Has anyone implemented odometry using BLDC hub motor hall sensors in ROS2? Any examples, tutorials, or advice would be greatly appreciated. submitted by /u/Organic-Author9297 [link] [Kommentare]
AI Piano Tutor on the Way...(reddit.com)

Instead of just watching videos or apps, this system uses a dual-arm gantry with five-finger robotic hands that: - Precisely control each finger’s position and pressure on the keys - Use compliant (flexible) actuators for natural-feeling guidance instead of stiff pushing - Start with strong support and gradually reduce assistance as you build real muscle memory It turns passive learning into active, embodied practice — helping you feel the correct movements directly.
