Lead-time notes from the package

  • Package caveat USD prices are the README's 2024 US figures (leader total $199, follower $278); EUR/GBP/CNY/JPY prices are kept as notes. Robotis prices and Amazon listings may have changed since the repo's last commit (Sep 2024).
  • Package caveat Leader and follower tables both list the Waveshare board, jumpers and a table clamp; the screwdriver and USB cable sets are listed twice upstream but the footnotes say buy once, so they appear once here.
  • Package caveat The leader board runs at 5 V although the Waveshare board is rated 9-12.6 V; the README says this is intended (footnote 14).
  • Package caveat The assembly video predates the screwed Leader_Platform and the LeRobot motor-setup order; follow the README and LeRobot notes where they differ.
