This is an epuck2 Robot which has
Kinematics & Orientation (IMU)
• Accelerometer: Measures 3D linear acceleration to detect movement and impact.
• Gyroscope: Measures 3D angular velocity to track rotational speed and orientation.
• Magnetometer: Acts as a 3D digital compass to detect magnetic fields and orientation relative to the Earth.
Environmental & Proximity
• Infrared (IR) Sensors: 8 proximity sensors distributed around the ring of the body to detect obstacles up to ~6 cm away.
• Ambient Light Sensors: The same 8 IR sensors can double as light intensity detectors to measure surrounding brightness.
Audio
• Microphones: 4 omnidirectional digital microphones arranged around the robot, allowing it to detect sound presence and perform sound source localizatio
