Use a sturdy double-layer corrugated cardboard box slightly larger than the robot. Place foam padding at the bottom of the box for additional support. Secure the robot in the center using foam sleeves or boards to prevent movement. Protect fragile parts with foam sleeves or boards. Fill empty spaces with foam beads or pads to absorb vibrations. Seal the box securely with adhesive tape. Label the box with the delivery address, contact information, and cautionary signs.
