=**Activity One**=
 * 50 cm and no more**

1.a) **For this activity we will need to learn how to program the robot to travel an exact distance using the measurement details provided.**

1.b) **The factors which will effect the success/failure of this misson are:**
 * - the surface on which the robot is travelling**
 * - the speed the robot is travelling**
 * - the size of the wheels**

1. e) Task 1: media type="file" key="reflection-1mp3.mp3" width="240" height="20"

In this task, we had to program our robot to move exactly 50 cm from the start line to the finish. To complete this task, we used the measurement of the radius of the NXT robot wheel, and divided it by the distance we needed it to travel. This was a successful way to complete the task, and we completed to the best of our ability and in an appropriate amount of time.

=**Activity Two**=

**There and back again.**

 * 2.a)** To complete this task, we need to learn how to make our robot turn at an axis for a certain amount of degrees. We also need to use the knowledge from the first task about the exact length that the Robot travels.

- the surface of the floor on which the robot is driving - the degrees by which the robot turns - the length by which the robot must travel
 * 2.b)** The factors which will effect the success/failure of this mission are:

 * .e) Audio reflection**

Task 2: In this task, we had to program our robot to drive straight, turn around and return to its starting position. This task required some trial and error to allow the robot to complete the activity. We used the skills we learnt in the first task to assist us in the successful completion of this task. The programming was fairly easy, but we had to be sure of the placement of the robot.

=** Activity Three ** = ===** Brace, Brace, Brace ** ===

**3.a)** For this task, we need to learn how to program an ultrasonic sensor so our robot doesnt collide with another robot. We also need to learn how to build the robot to add a sensor that will work effectively. We also need to know how to adjust the distance that the sensor will pick up objects in range.
 * 3.b)** The factors which will effect the success/failure of this mission are:- the placement of the sensor- the surface that the robot is driving on- the distance of the objects from the robot

 * 3.e) Audio reflection**

media type="file" key="reflection-3mp3.mp3" width="240" height="20"  Task 3: In this task, we had to use the ultra sonic sensor to avoid collisions with other robots and objects. We had to use a simple loop program and correctly program the sensor. The construction of the sensor was quite simple and worked were effectively After some practice, we were able to successfully ensure that the robot did not collide with other objects

**Activity Four**

** Edge Finder **

 * 4.a)** For this task, we need to know how to build and program a light sensor. We need to know how to use a loop system and how to view the levels of light on and off the desk to set the sensor.
 * 4.b)** The factors which will effect the success/failure of this mission are:- correct programming of the sensor- light levels in the room at the time of output- the surface on which the robot is driving- the size of the table

Task 4:

In this task, we had to use the light sensor and a simple loop program to safely navigate our robot around a table top. We had to use the level of light reflection on and off the desk to program our light sensor correctly We had a few problems in the beginning and our robot fell off and broke, but after a few adjustments to the program, we were able to make it navigate successfully. =** Activity Five **=

** Walls and edges **

 * 5.a)** For this task, we need to know how to build and program a touch sensor so that the robot can navigate around a room/obstacle course by sence of feel. We also need to make sure the robot doesn't get stuck while trying to avoid an object.

- the building and sensor program - the object being tall enough for the robot to hit - the surface on which the robot is travelling
 * 5.b)** The factors which will effect the success/failure of this mission are:

media type="file" key="reflection-5amp3.mp3" width="240" height="20" Task 5:

In our final task, we had to use the touch sensor to move our robot around a room and negotiate collisions. We programmed our robot so that when the sensor is activated, it reverses away from contact, turns, and continues its journey. This task worked quite successfully on our first try, and only a few small adjustments were needed to make it 100% effective ** Portfolio: Hardcopy **
