You have used your unique biology to bud off a biological drone you can more easily integrate with.
Drone class feature, adaptation or early stage adaptation racial trait.
Your drone has living components. You can use Medicine instead of Engineering to repair it, and your drone naturally heals to full Hit Points when you rest for 8 hours. A drone modified in this way is considered an aberration rather than a construct for the purpose of spells and effects targeting it. In addition, Life Science and Medicine become class skills for you.
