9.+NXT+ROBOT+TASKS

__**50 cm And No More**__ -The length of the radius of the wheel (28mm) -The length of one revolution (17.2cm) -The length between the front of the wheel and the front part of the robot (2.1cm)
 * Before we could complete this task, we needed to know:**

**Factors that will affect the success/failure of the robot:** -Accuracy of the measurements -Friction between the carpet and the wheels -Size of wheels

__**There And Back Again**__

-We needed to know how to program the robot to do a point turn -We needed to know which ports to connect to -How to use the power controls and coast/brake buttons -We used trial and error
 * We needed to know a few things before we could start this task. They were:**

-The friction between the wheels of the car and the carpet -We had to make sure that the wheels were aligned with the line and that the robot was aligned properly to travel in a straight line -Using the correct controls
 * Factors that would influence the success/failure of the robot:**

**__Brace, Brace, Brace__** **Record of what you need to before completing this task:** -Knowing which port to connect the robot to -How to use the Loop control properly -How to use the sensor properties eg. Stopping distance
 * -**How to connect the ultrasonic sensor to the brick

-The set-up of the robot -Distance from obstacle eg. wall had to be correct -If the sensor works properly -If the area in which the robot was going to be tested in was too clustered, the robot would be too “confused” -The size of the objects could affect stopping eg. too small=undetected
 * Factors that would influence the success/failure of the robot:**

__**Edge Finder**__ **Record of what you need to before completing this task:** -Know how to connect the light sensor to the brick properly -How to measure the light level using the sensor -How to program the robot to respond properly to the light levels -Stopping, reversing and changing the direction of the robot

-Connected properly -Light levels on the different sides of the table -Correct calculations
 * Factors that would influence the success/failure of the robot:**

**__Walls And Edges:__** **Record of what you need to before completing this task:** -How to connect the touch sensor to the brick -Which ports to connect to -How to program the robot correctly -How the sensor worked -How to build the activator

**Factors that would influence the success/failure of the robot:** -Types of obstacles -Built properly -Programmed properly
