These are the traditional giant fighting robots. They tend to be humanoid in shape. They are all capable of moving in 'walk' mode, and some have hoverjets or wheels installed to allow them to 'skim' or 'roll' as well. Battroids are the 'base' to which other types of mecha are compared. Most mecha in the game are Battroids.
+1 MV, +1 TR. (The game's been written in favor of Battroids...) Your basic walking mecha. Can wield shields.
