TASK 1: 50 cm and no more I need to know how far one wheel rotation goes so that i can calculate how many rotations the robot will have to complete in order to move as close as possible to the lego man and not knock him over.
 * 1. What do you need to learn in order to complete the task? (eg how a touch sensor works)**

The factors which will effect the robot's performance are the placement of the back wheel. It has to be straight otherwise when the robot starts moving forward it will turn slightly which will change its course and will not give us optimum results. Other factors are the friction of the carpet against the robot's wheels.
 * 2. Asses the factors which will affect the success/failure to each mission. (eg the floor covering on which the robot will be run, size of the wheels etc)**


 * 3. A screen shot/capture of the program for the activity:**

 * 4. An edited video (embedded) of your robot attempting/accomplishing the activity. (eg should include an opening title- activity one)**

media type="file" key="audio_reflection1.mp3" width="240" height="20"
 * 5. An audio reflection about the process of completing the Activity. (eg in Activity three, we thought it was fairly straight forward, however we didn't realize that we had to use a loop. Record this is audacity and save as an Mp3 file)**

TASK 2: There and back again

You need to learn how to make a robot stop and turn and move forward again. You need to learn how the degrees work in the programming.
 * 1. What do you need to learn in order to complete the task? (eg how a touch sensor works) **

A factor that will affect the success/failure of this mission is the carpet, because the friction is causing the outcomes to be slightly different than what expected. The other factor is the back wheel. When the robot turns the back wheel is not pointing straight ahead so when the robot begins to move forward again its movement forward is affected slightly by the wheel which causes it to change direction slightly and as see in the video below.

TASK 3: Brace, Brace, Brace

You need to learn how an ultrasonic sensor works to be able to adjust it properly to serve its purpose.
 * 1. What do you need to learn in order to complete the task? (eg how a touch sensor works) **

The factors include the angle at which the robot meets the wall or object. If the robot is moving parallel to the wall with the slightest degree of movement towards the wall the robot will get confused before it figures out hot to get away from the objection completely. Other factors are the distance that you set the ultrasonic sensor to respond to when approaching and objection. If it is a bigger distance then the chances are the robot will not collide with the objection while turning around and away from it. The bigger the distances the better, but you don't want the distances to be too big either.
 * 2. Asses the factors which will affect the success/failure to each mission. (eg the floor covering on which the robot will be run, size of the wheels etc) **

TASK 4: Edge Finder

For this task i need to learn how a light sensor works and how you can use it to test light sensitivity.
 * 1. What do you need to learn in order to complete the task? (eg how a touch sensor works) **

The shades that happen to be there from the sun change the light sensitivity from one side of the table to the other which means the light sensitivity that you adjust your robot to has to be broad enough to cover any spaces on the surface area. This is because the robot will get confused when its own shade interferes with it while it's in motion. If you adjust your robot to turn at the last minute the robot might fall down while it tries to turn around, so it has to be programmed to move back turn and continue on.
 * 2. Asses the factors which will affect the success/failure to each mission. (eg the floor covering on which the robot will be run, size of the wheels etc) **

TASK 5: Walls and edges

I need to learn how to build an activator and how a touch sensor works.
 * 1. What do you need to learn in order to complete the task? (eg how a touch sensor works) **

The main factor of influence would be the carpet which won't allow the robot to turn comfortably when it tries to get away from the objection due to the friction. Others would be its programming to move away from the objection in a successful manner which includes getting away from the objection completely so it doesn't move into it again.
 * 2. Asses the factors which will affect the success/failure to each mission. (eg the floor covering on which the robot will be run, size of the wheels etc) **
