You want to be an engineer and the only application you are aware of for that field is robotics?
Engineering covers a variety of fields from chemical engineering to computer science, as well as game design. Based on your activities you seem way more interested in performing arts. Film and theater at USC are highly competitive. Admittance to Viterbi is also highly competitive, although not quite in ivy range as with film/theater. You do not have a strong application for engineering. Anyone reading your application would get the sense that you are picking a reputable major you think you might be able to get into, in the hopes that you can transfer into theater later on. Perhaps you ARE really interested in engineering, but if you want to apply for that major you should research engineering so you have a better understanding of its many different branches. You do have the option of applying undeclared to Dornsife, which you have a good shot at.
