-    * The Khepera IV proximity ​sensor is a set of 8 infrared emitter/​receiver pairs distributed regularly in a ring around the robot. The sensors are numbered 0 to 7. Sensor 0 looks straight ahead, and the numbers increase counterclockwise when looking at the robot from above.+    * The Khepera IV light sensor is a set of 8 infrared emitter/​receiver pairs distributed regularly in a ring around the robot.
