Electric Self Balancing Uni-Cycle

This paper deals with the design and construction of a low cost electric vehicle aimed to demonstrate the possible alternative to the present personal electric transportation in India. The increasing rate of urbanization and increase in use of motor vehicles is the principal cause of energy invasion, greenhouse gas emissions and environmental downturn. As a unique and eye catching transportation device, Uni-Cycle may offer several problem minimizing solutions over the current environment decay issue. Uni-Cycle is aimed to feature the self-balancing mechanism similar to that of the ‘Seg Way’ but with single wheel. This self-balancing works on the principle of inverted pendulum. The computation of the sensor values is done in real time system. The traditional PID control implemented combines the result form sensor to the DC motor speed controller. The power source of Uni-Cycle is a lithium polymer battery, capable of working in short distance area. Bike riding gestures are used as the human input to the transporter. Leaning of the rider in forward or backward direction decides the direction of motion of the device.
