Task+4

Activity 4 a. In order to complete task four ‘Edge finder’ we are going to have to attach the light sensor to the robot. The aim of this task is for the robot to navigate safely around a square table top. It is going to need to roam around freely, measuring the level of reflection of light from the table top. When the light sensor goes over the edge the robot will then stop, reverse, turn around and move forward continuously until reaching another level of light reflection. Too perform this task accurately we are going to need to learn how to program, and build the light sensor onto the robot. With the knowledge from activity three we already know how to add a loop, stop, reverse and change direction, therefore making this activity easier.

b. Some factors that will contribute to this task is amount of area that takes up the table top, and the fall if the robot crashes of the table which may cause damage to the robot and can stop the robot from completing the task.
