Coming from India, where two-wheelers form a major portion of the traffic, accidents due to loss of balance are common place. The self balancing two-wheeler project was initially started to decrease these accidents and as the project took shape it also grew into an intuitive trainer, helping the rider hone balanacing skills. This book, takes you through the basics of the principles involved in balancing a two-wheeler - contact polygon and gyroscopic effect. It explores the stability of a two-wheeler and also the previous attempts made to balance it. The combination of the concepts and the integration of the principles along with the proof of concepts are covered. It also guides you through the steps of building a basic system to realise the aforementioned goal. Both the construction and the problems involved are discussed and scope for future work defined. Two-wheeler manufacturers and university students looking for the next innovation and improvement in existing two-wheeler technology should find this work interesting.
