hi, thanks for your reply , the problem is i bought just 4 sensors from the above one (single detector) and the rest bought that product http://www.lynxmotion.com/Product.as...7&CategoryID=8

it just uses schmitt trigger , i wonder , if it will work or not with this year surface

, im so scared really cuz we paied alot for that order.

also i've another problem , i tried to PWM the two motors to let the robot move in straight line , also it didnt work , there's also some steering to the right wheel and it bends to right , tried to tune the pwm delay , didnt work , is this a problem from the mechanical design or what ?

also i've seen many videos on youtube , i wonder how do you make the robot move fast and in straight line like that ?
also i noticed that you use small diâmeter of the wheels , it does affect ?

also do you use new motors or used motors for the driving wheel motors ?

also , how do you achieve PWM and at the same time on the motor and use line tracing ??
thanks alot .
