As I started to slowly develop this DOCBOT world and comic book I would sketch of all types of things like environments, other characters, equipment, etc. Here are some early roughs of other robots the main character might interact with. These are quick pencil sketches. In the end I am not sure what might be used but I have them to refer to and build upon. This process will always be an ongoing one as I create new stories, pick up new influences, etc.
