finishing up my blog 2

i did come across some problems of how to program the light sensor but to get the best result i positioned the light sensor in 3 different places and tested them to see which one worked the best for my robot. i stuck with the one at the center front (as you can see on the pics of my robot). because it obviously saw the white light and turned away.

 I also had trouble with the ultrasonic sensor working properly so i tested it in 2 different positions again to get the best result. the 1st position was on the top at the back which didn't work very well the 2nd position was at the front which was attached to the light sensor which was a problem because if the opponent attacked my light sensor then my ultrasonic sensor would be on a slight angle facing the ground which would be problem because then my robot would only see them if they were even closer and would hinder my chances of winning. so i reinforced the ultrasonic sensor to hopefully stop it from doing so but in a couple of the fights the reinforcement didn't work as planned and broke off a couple of times but i was already in the competition and it was to late to change it so i stuck with it.
