Robustus is out of Polyhex for a little drive around the nearby environs that are Decepticon held. He's not on the lookout for anything or anyone really. If he happened upon the Skorponoks, well he could try talking with them or at least observing them before radioing them in to someone that could handle them. Lifeline is out in the 'wilds' as well, though for a different reason from Robustus. She's still collecting raw materials for the part she has to reforge from scratch, and this is the most likely area to find the next metal on her shopping list: zinc.
