Arduino Shield Bot 1.1 not working...

Hello

I'm curently using an Arduino Shield Bot 1.1 in order to make a line follower robot.
To test it and make sure it works, I just made a little program making the robot going forward.

#include <Shieldbot.h>

Shieldbot shieldbot = Shieldbot();

void setup(){
Serial.begin(9600);
shieldbot.setMaxSpeed(255);
}

void loop(){
shieldbot.drive(127,127);
}

I took this program from the examples of the library of the Shieldbot and made sure it was working, but when I transfer it on the card, the Shield Bot doesn't go forward as it was ordered.

I looked up the Arduino Uno to verify if the program was well transfered and it was. I also checked the battery and the motors and they both worked. I did the same test on the inputs of the Shield Bot and it worked aswell.

But still, the robot is not going forward. I don't think it's broken because I just bought it but I don't know how to find out the problem.

So I'm now curently looking for some help in order to make this Shield Bot work, I didn't find anything anywhere.

I hope the problem is well explained and that you will be able to help me.

Did you ever get your Shield Bot working? I've having the same problem with a pair of Shield Bot v1.2.
