    1. Claude Code skills for ROS 2 Jazzy that route to official docs instead of guessing APIs (measured before/after included)
    2. I got an old Puma 500. Any advice for building your own DC motor servo drives?
    3. What information do hardware startups most often forget before sending a design to manufacturing?

    1. Bob (my robot) died 😢 I tried consolidating 2 LiPo batteries into a 1 larger one and fried its Raspberry Pi brains. I'm gonna rebuild him with a Nvidia Jetson brain and RealSense D457 GMSL camera.
    2. Playto Labs is a scam
    3. Updated my browser-based Obstacle Avoidance Robot Simulator—looking for feedback from the robotics community
