Sonic the Hedgehog (2006)
The robots make their first appearance in the 2006 game. They don't appear in cutscenes, only during the levels. They, and the walkers, attack the player until destroyed, or until the player gets too far away from it for it to attack. The robots are not as common as the Gunners and flyers in the game. The cannons don't play a much major role in the game, and they have a very much minor role in the game. They appear in levels where robots are. The robots are do not appear much during levels where Iblis's minions are the enemies, though. During the course of the game, the cannons and walkers will prove to be quite tough to defeat, due to their armor strength.

The robots appear even in Wave Ocean which, for Sonic, is one of the earliest stages he goes to, and these are robots that you would think would appear later on in the game. The Robots are seen in nearly all Sonic levels (except Crisis City). The cannons/walkers have not appeared in another game since the 2006 one.
