# BiBoard Preparation Plug in the battery and press the battery button for 3 seconds to power on the robot. There are two methods to connect to the computer: * The USB data cable connection must be made directly to **the BiBoard,** not to the battery's charging port. * You can also connect to the computer via [Bluetooth](https://guide.petoi.com/quick-reference/bluetooth-connection). For BiBoard, please ensure the program enters the [**regular startup mode**](https://guide.petoi.com/arduino-ide/upload-sketch-for-biboard#id-2.8-program-initialization)**.** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
