Battle Bots 2018

Dear Bloggers,

December 2018 was the time for the annual Battle Bot Challenge.  Needless to say the children were very excited all trying to build and program the ultimate robot.

The challenge was to design and build a robot with a downward facing light sensor, a movable arm and some defensive stucture/s.  The robots had to start facing away from each other, turn 180 degrees and use the light sensor to stay within the black line.  The winner pushed the other robot over or out of the ring.

The video is taken from above so it’s orientation really is correct.

Stopping at the black line

Dear Bloggers,

Years 5 and 6 programmed their robot to move forwards over a white ground and stop at the black line.  This involved finding a threshold value of % light reflected.  This was done using the view menu and measing the amount of reflected light that came from white and black.  These values were averaged and this value was used in the program. Here is video.

Follow That LIne

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.
