The speaker emphasized in his TED Talk that “A person can never be broken, and it is the technology that is broken”. I felt moved by these words, which convey the speaker’s belief that he and his fellows would definitely succeed in helping the disabled people feel not disabled anymore.
As a scientist in MIT, the speaker with his fellows intend to advance the technology to help the disabled people. He introduced many complicated theories and working process, in order to make the mechanical legs interact with the human body more like a real leg. One discovery is the “mirroring” theory, that is, the synthetic part becomes soft while the body becomes stiff, and vice versa. I think this discovery could be a breakthrough in the project, because it helps the mechanical leg “knows” how to react to the thigh’s reaction. As for the technical part to realize this “mirroring” effect, I can use the knowledge that I learned from the class to interpret it. The action of the thigh could be the “Input”. When the thigh is stiff, then the voltage becomes 0V, then the “output”, which is the mechanical leg, would be “compliant”.
Apart from helping disabled people, the great invention, exoskeleton also saved people’s effort and energy to run or do some hard movements. This achievement manifests that this interactive invention is not only make the mechanical leg be similar to the real leg and interact actively with the human body, but also take a step forward to improve people’s lives. In a word, the invention is not only for the disabled people, but is for all the people in the world.
