	When the gumstix extension is mounted on the e-puck2 robot, the same I2C bus is shared by all the devices (camera, IMU, distance sensor, others extensions), the main microcontroller and the overo; since there is only one master (the overo), these devices will not be anymore reachable directly from the e-puck2 main microcontroller that will act instead as I2C slave.<br/>		When the gumstix extension is mounted on the e-puck2 robot, the same I2C bus is shared by all the devices (camera, IMU, distance sensor, others extensions), the main microcontroller and the overo; since there is only one master (the overo), these devices will not be anymore reachable directly from the e-puck2 main microcontroller that will act instead as I2C slave.<br/>
