Both species have raised, bumpy warts on their mantles (the rounded part that looks kind of like a head) and on their

bumps go further down their
arms and mantles.
The best you're going to do there is Luna, a human - size «robot» that will soon be widely available from a company called RoboDynamics in Santa Monica, California, for $ 3,000 — incredibly cheap for a humanoid, but incredibly expensive for a device that can't do much more
than try not to
bump into furniture and senior citizens as it desultorily wheels itself around your home, toting a tray of drinks you've carefully placed on its precarious, pipe - like «
arms.»
