Title: Auto-balancing Bicycle
Description: The auto-balancing bicycle is modified from a hybrid electric bicycle. Using the steering control method, it can go forward, turn left and right flexibly at different velocities, providing a platform for unmanned bicycles.

The bicycle, as a widely used vehicle, and its driverless technology has become a research hotspot in recent years. Compared to driverless automobiles, bicycles have more flexibility due to their small size and more difficulties due to their two-wheel structure. Bicycles will fall down without any control, while automobiles don’t have this problem. Therefore, the major challenge faced by driverless bicycles is designing a control system to make the bicycle remain balanced and achieve flexible steering.
The dynamics of the bicycle is a complex nonlinear system, while the parameters of bicycles are difficult to obtain accurately and the disturbance of the environment is unknown. Thus, the control system we designed needs to be robust and stable enough to resist those internal and external disturbances.
For more information regarding the detailed bicycle dynamics model, control system and software-hardware descriptions, look at the attached document "Auto-Balancing Bicycle Technical Report".
