Leo Boghozian built a robotic hand for his senior project which he is able to control with the movement of his own hand. The point of this project was to demonstrate why having engineering programs such as robotics is important for those students who want to major in engineering.
Students improve and develop their skills in handling pressure, teamwork, and communication in order to be prepared for upcoming challenging projects. The robotic-arm itself works by using nylon strings to manoeuvre hand-like digits.
It is made from a thermoplastic palm that translates movement from the student's wrist to the fingers. It was not perfect, the robotic arm had some pitfalls, like the inability to grasp anything unless it was "tightened" just right, but Boghozian was able to hold things like bottles or cans with the robotic arm.
He used a 3D Printer for the entire design and it was made functional by adding a nylon thread. Leo Boghozian has designed the next step of the robotic arm, which he calls the Gen 2. The purpose of this version is to help move a patient's wrist that has been damaged by an accident by pulling their hand inward and outward.
The Gen 2 was also more simple to design and to 3D Print:
