Moderator note: I'm removed your second post since Science Buddies guidelines request that students not post more than once. Please be patient - the experts here are volunteers so they have other commitments. I did modify the title of your post so the experts can see more details about your project. Thank you and good luck with this fascinating project!

Hi Slinja,

We have a project about making a robotic hand, you might want to check this out: https://www.sciencebuddies.org/science- ... robot-hand

Hope that helps!
