Bio-medical engineering is a field that requires all STEM Components to create an end product that can benefit the human population. It is observing surrounding and making an adaption of something. How do you think helicopters were invented? By observing the flights of dragon flies of course. The shape and design of a helicopter is based on the body of dragonflies. Adaptions are to be made in things, so that we could put this "new" technology to work for us.
The motivation to design the Robotic hand came to me after my teacher told me how muscles worked. I was able to take this simple idea and transform it into the "technology" language. The engineering process is all about finding the problem and then finding ideas that could potentially solve the problem. The problem here was to make a "prosthetic hand" that could be used in many objectives like; replacement hand for people that have lost hands, hand that can treat and deal with radioactive materials for humans, and an education tool to clearly show how our muscles work. Well, of course the hand that i have built is not perfect to work in these situations, but I attribute that to the limitation of time and resources.
Taking a human hand and evolving it to mechanical applications, building giant arms in the industry world is already in movement. An example would be Those giant mechanical hands that are used to build cars. Mechanical hands are the doctors of the future, because these robots will be programmed to even fix cars or maybe even give medical operations to men. Virtual Video games are slowly becoming reality, because people build robots that could analyze, and then build them so that it makes a job easier. We may even have robot waitresses serving our food in 20 years.
