Hi, I have heard about the robot arm, that works just like the human arm. I think that must be the solution for my grandpa who has been having some problem with his paralytic arm. He was an army person, so he never likes to be a dependent on others. I think this kind of a robot arm will help him a lot with his daily activities. What do you guys think? Please tell me all about these kind of robot arms and also how they can be helpful for partially invalid people like my grandpa?
