Jeeves' specs, in Book 8 format:
JVZ114167 55202-A2-NP328-FD94 Cr394,150 212 kg
Fuel=62.4 L Duration=13 days TL=15
2 light arms
2 eyes (light intensification, passive IR), 2 ears, olfactory (extra sensitivity), taste, touch (extra sensitivity)
brain interface, power interface, radio (regional range), zero-G maneuver, 2 LT grav modules
emotion simulation, medical-2, ship’s boat-2, steward-2, valet-2, grav vehicle-1, rescue-1
Note that the grav modules are not sufficient to support his mass in 1G gravity—they just make him as light on his feet as a gentleman's personal gentleman is supposed to be.
EDIT: for those who don't have Book 8 and can't read those codes up there, Jeeves is a "contoured" robot, meaning that some effort has been made to give him the shape of a human being, but no one could mistake him for one except in a very dark alley. Anyone is welcome to look for a picture.
