Computer Science Case

Computer science (known as computing) is a branch of engineering that studies (with the use of computers) computable processes and structures. Due to large scale processes that need to be undertaken with the highest form of accuracy as well as limited time consumption, computing has allowed the introduction of artificial intelligence through the use of robotics. A robot is an automatically guided machine that has been programmed to have the ability to carry out tasks on its own. These tasks range from movement between obstacles, to lifting objects. A common and basic concept of a robot is Lego’s NXT Mindstorm.

Sensors

The NXT Mindstorm robot has four sensors; sound, light, ultrasonic and a touch sensor.

Light sensor: detects the light level from one bearing. Using the integrated red LED the light sensor is capable of sensing either ambient light or reflected light values. There is a scale of 0 to 100 for sensor of light. This is for the intensity of light, on the scale of 100 being very bright and 0 being completely dark.

Sound sensor: measures volume altitude on a range of 0 to 100, 0 being absolutely silent and 100 being extremely loud. This sensor can also be programmed to control the activity of the robot depending on the level of volume.

Ultrasonic sensor: detects movement in addition to determine the distance from the sensor to an obstacle that is opposite to it. It can measure the distance between the robot and an obstacle by measuring the reflection of the light that is emitted. The ultrasonic sensor emits waves that reflect of an object and the sensor counts the time it takes for the wave to return back.

Touch sensor: detects if it is in contact with an object or not, the scale is either a 1 or a 0, 0 being the value given if it not in contact with an object and 1 being the
