Hello, my name is Devin and I am an engineering student at I

Hello, my name is Devin and I am an engineering student at Independence School District in the United States. I had an assignment where I had to find three problems and define them (research, possible solutions, etc). Anyway, I'm here on this site to ask you guys/gals what you would want in a prosthetic limb. It can be whatever limb but I'm trying to focus on just the hands for right now that way it doesn't bog me down if you know what I mean. Don't worry, there's no such thing as a bad idea here, feel free to respond with whatever you want.

Oh, and in case anyone was wondering, yes I will upload photos of the ideas I have already. However, I'm still finishing them up so it'll be a minute before I actually get them uploaded. Thanks again for your input, it's really appreciated.
