Hy ,
I am trying to build line follower for rescuejunior with my kid.
We made line following robot and one victim searcher that works with two ultrasonic sensors one for wall following in rescue zone and one for victim finder it works on distance change detection beacose where the victim is there is sudden change in distance. And now is problem in changing beatwin this two programs beacose on our competition there is no silver line in entrace to victim zone. So we decide to count eather doors or line gaps...
Any sggestions with this? And this is not for building robot for competition but just for play. If anybody have some example of working sketch i would apreciate it. We work with minibloq beacose i have litle knowlahe about c programing and my douther is 9year but i am learning now arduino couse she shows interes for programing
