For my thesis project I have a female robot character that plays a mayor role. Designing her has been a challenge but fun. Got the idea to make her face a display that shows a real female face. That way she can show all range of emotions without looking to static or dead. I really want her to be a strong character. On top the display can show other things like status reports or maps and could even be a touch screen.
Here is a battlesuit concept. Since I would think that even in the future ground combat would always be necessary the question is how would it evolve. Would there even be humans inside these suits?
