Rowbot is used near the beginning of the game to help Niko reach the second area, the Glen. As it is not tamed, it has little personality, and strictly follows its code. Though, there are several times where it seems pleased to get assistance from Niko, likely due to it being able to follow its code again.

There isn't a lot to go on when it comes to Rowbot's voice, but I can't imagine it being too high or low. 

A robotic effect is optional, but if you do want to include it, please provide a take without it!
