Sounds pretty good, here's an idea of mine:

Clawbot

Movment type: Small wheels

Base Armor : Scout

Base Speed : 8/10

Basic Equipment : Two slash arms, tipped with razor blades, short range but powerful.

Appearance : Short, sort of like an upright lizard. It can attack in front and behind it.

Limitations : Unable to attack anything above or below it.

Terrain Favorablilities : Forest, Cramped areas, Flatlands

Terrain no no's : Mountains, Cliffside, Very Open Areas

Rarity : Common, but fading out in later game

Equipment : Upgrades are rarely avaliable.

Special Upgrades : Swivel arms, which allow it to target in a circle around the robot rather than just in front and back.
