631 model B1 battle droid

The 631 model B1 battle droid served in the Clone Wars.

Characteristics
The 631s were known to be dumber and clumsier than other B1 models.

History
These droids fought in the Clone Wars, with some serving onboard the Skytop Station. A battle droid commander asked a 631 unit to carry an important item without dropping it, upon which the droid immediately tripped and dropped the box. This elicited a negative comment from the other droids about the 631 model in general.
