Prosthetics are like small machines that help people. "Bionic" means using small machines to help us do things, so prosthetics do make us bionic. We see what people with prosthetic limbs can do, how to make a simple robotic hand, how prosthetics are made, prosthetics powered by electricity, 3D printing of prosthetics, prosthetics for animals, exoskeleton prosthetics for paralyzed people or construction workers, controlling prosthetics with your mind, and the future of prosthetics.
