I see I didn't get lucky with that description! How about something like this?
Well you know how it goes. Sometimes the dice are not in a generous mood.
This entity is obviously not a living creature, but a construct of some sort. Its body is human enough in shape, but it is metallic, rather than flesh, with clear crystal lenses for eyes.
Let's see...
This entity appears to be formed from some smooth, shiny material - possibly some kind of metal or enamel. Humanoid in form, its jointed limbs and inflexible torso make it resemble a tailor's mannequin or life-sized puppet more than a living being. Its face is an immobile mask set with clear crystal lenses for eyes.
A droid is an artificial creature manufactured by nonmagical technologies far more sophisticated than exist in most known worlds. The valet droid is a domestic model designed to work as a personal attendant or household servant. Valet droids come in many different shapes and appearances. The differences between them are mainly cosmetic - a valet droid that looks like a spider-centaur may have identical internal mechanisms to one that looks like a dwarf. A typical valet droid resembles a simplified image of its owner's race sculpted with an expression of benign attentiveness.
Valet droids have built-in safety codes that prevent them from attacking any member of the race or species that created them, as well as any being the droids' creators intended them to recognize as an "owner race". For example, a valet droid built by spacefaring elves might refuse to attack an elf or any living creature that is even vaguely elf-shaped, including most humanoids and fey.
These safety codes mean valet droids are normally incapable of combat, even in self defense, unless they recognizes their opponent as not being a "creator" or "owner". Unscrupulous owners occasionally reprogram their valet droids to fight, but their safety codes usually still prevent them from injuring members of the "creator race".
However, valet droids built by alien beings may not recognize standard humanoids as being sapients, let alone "owners", in which case they would have no safety codes against attacking them. Such alien valet droids might treat a dwarf or human no differently to how they would treat a wild animal.
Droids can speak a special language of buzzes and beeps called Code. There are many dialects of Code, most of which are mutually unintelligible. A valet droid speaks Code Standard (the droid equivalent of Common).
In addition, most droids are capable of normal humanoid speech. A standard valet droid speaks Common and one other language, such as Elven.
A valet droid's anthropomorphic body stands 5 and a half feet tall and it weighs 150 pounds.
COMBAT
Valet droids were never designed for combat. They will only fight to defend its owner or a "creator". If something attacks the droid itself, the machine tries to avoid the threat unless its orders specify otherwise (e.g. if it was forbidden from leaving its post, or instructed to kill or capture any "wild animals" that intrude upon the premises).
A valet droid is a inexpert combatant who unimaginatively follows whatever battle tactics its owner orders it to use (provided these do not breach its built-in safety codes). Despite these failings, they are fearless and implacable, continuing to fight until they are destroyed, immobilized, or their instructions change.
A valet droid's slam attack is treated as a secondary attack and adds only half the droid's Strength bonus to damage.
