# In-depth Contents

During our four-year journey of building the Berkeley Humanoid Robot, we’ve encountered countless challenges—frustrating bugs, unexpected setbacks, and moments of doubt. 

While many great resources already exist, we felt compelled to document our learnings and discoveries here, hoping they might serve as a meaningful contribution to the robot DIY community. 

We sincerely wish you never have to battle the same stubborn issues we faced, while working on Berkeley Humanoid Lite and other projects. But if you do, may this guide save you time, ease your frustrations, and remind you that every challenge conquered brings you one step closer to creating something extraordinary.
