Dear Bloggers,

Years 5  and 6 programmed their robots to follow a black line using a light sensor.  The secret was to follow the edge of the line.  The student sued the view menu and maths to calculate the threshold value for the % of reflected light. The program used a switch to make the robot turn into the line when it sensed white and turn out when it sensed black. Have a look at the video.

Thanks for calling by
