Based on my professor’s suggestion I went with project proposal 3, a user experience for an implantable microrobot. I did a lot of talking to people in my network to get some ideas going and then I did some research based on those ideas and found some great news articles and links that helped me define what my microrobot experience would be about.
Here are some interesting related articles and links:
