This mechanical project is about the construction of a segway. The Segway is a small footprint electrical vehicle designed by Dean Kamen to replace the car as a more environmentally friendly transportation method in metropolitan areas. The dynamics of the vehicle is similar to the classical control problem of an inverted pendulum, which means that it is unstable and prone to tip over. This is prevented by electronics sensing the pitch angle and its time derivative, controlling the motors to keep the vehicle balancing. Making this project would be an interesting job because it requires use of technology but in a way to make it environment friendly. This project is designed for energy efficient transportation industry. Global warming is one of the alarming issues that is being talked about. The main cause of global warming is the use of renewable energy sources. The way to prevent global warming is use of non-renewable energy sources or to design environment friendly vehicles that would cause negligible or no pollution. This project is example of environment friendly design. Hence, this is a useful and knowledgeable project from future perspectives.
