[waitwhat?]

Perhaps a good place to start would be the "First Behind the Design" books that were published a couple years ago. They include extensive overviews of successful robots from specific years. You could include some of these in your presentation or atleast use the books as a starting point for recomendations on robots that would be worth researching?

Here's the amazon links:
