Erreur de compilation Arduino IDE

Bonjour,

Je suis étudiant en électronique depuis peu et j ai recu le magnifique “ALLBOT - Four legs” pour m aider a apprendre.
Je vous écris car lorsque je veux téléverser le programme Allbot vers l aduino du robot la console me signale des erreurs de compilations…

N’étant pas très fort en programation, je suis incapable de comprendre le problème seul et c est après des heures de recherches en vain sur internet que j implore votre aide.

voici donc le programme suivit des erreurs signalées par la console:

#include <Servo.h>
#include <ALLBOT.h>

ALLBOT BOT(8); //number of motors

enum MotorName {
hipFrontLeft,
hipFrontRight,
hipRearLeft,
hipRearRight,
kneeFrontLeft,
kneeFrontRight,
kneeRearLeft,
kneeRearRight
};

int sounderPin = 13;

String rawcommand; // Global variable that stores the raw received IR command
String command; // Global variable that stores part of the decoded IR command
int times; // Global variable that stores part the received IR command
int speedms; // Global variable that stores part the received IR command

boolean IRreceive = true; // Set this to true if you want to use the IR remote
boolean receivelog = false; // Set this to true if you want to see the serial messages for debugging the IR commands

void setup() {

//NAME.attach(motorname, pin, init-angle, flipped, offset-angle);
BOT.attach(hipFrontLeft, A1, 45, 0, 0);
BOT.attach(hipFrontRight, A0, 45, 1, 0);
BOT.attach(hipRearLeft, 9, 45, 1, 0);
BOT.attach(hipRearRight, 4, 45, 0, 0);

BOT.attach(kneeFrontLeft, 11, 45, 1, 0);
BOT.attach(kneeFrontRight, 2, 45, 0, 0);
BOT.attach(kneeRearLeft, 10, 45, 1, 0);

}

}

}
}

Hello,

I am a student of electronics recently and I received the magnificent “ALLBOT - Four legs” to help me learn.
I am writing to you because when I want to upload the program Allbot to the robot aduino the console informs me of compilation errors …

Not being very strong in programming, I am unable to understand the problem alone and it is after hours of searching in vain on the internet that I implore your help.

Here is the program followed by errors reported by the console: (see above)

The error is mainly to do with this:

sketch_dec07a.ino:107:20: error: ‘class String’ has no member named ‘remove’

It seems like your arduino installation is corrupt. Please try to reinstall the arduino IDE.
