Intro
For this tutorial we will be using the Explore Robo kit. You may go ahead and download the schematics and other details from the link.
To give a brief the Robo Controller board has a CP2102 USB to UART(Serial) convertor. We give commands to the robot from the terminal and move it. This is a very simple type and you can easily hack it. The controller board also has a atmega8 MCU with Arduino bootloader, hence we can code it from the Arduino IDE
#include <Firmata.h> int MotorLeft[2] = {A0,A1}; int MotorRight[2] = {A2,A3}; void setup() { Serial.begin(9600); MotorInit(); Serial.print("*Explore Robo Mode Computer: Controlled*\n\r"); Serial.println("Commands:\n W->Forward \n S->Backwards \n A->Left \n D->Right"); } void loop() { int command; command = Serial.read(); switch(command) { case 'w': Robot_Forward(); delay(100); break; case 's': Robot_Backward(); delay(100); break; case 'a': Robot_Left(); delay(100); break; case 'd': Robot_Right(); delay(100); break; //in case the caps lock is ON case 'W': Robot_Forward(); delay(100); break; case 'S': Robot_Backward(); delay(100); break; case 'A': Robot_Left(); delay(100); break; case 'D': Robot_Right(); delay(100); break; default: break; } } //Intialize the motor void MotorInit() { int i; for(i=0 ; i<2; i++) { pinMode(MotorLeft[i],OUTPUT); pinMode(MotorRight[i],OUTPUT); } } //Robot Driving Functions void Robot_Forward() { digitalWrite(MotorLeft[0],0); digitalWrite(MotorLeft[1],1); digitalWrite(MotorRight[0],1); digitalWrite(MotorRight[1],0); } void Robot_Backward() { digitalWrite(MotorLeft[0],1); digitalWrite(MotorLeft[1],0); digitalWrite(MotorRight[0],0); digitalWrite(MotorRight[1],1); } void Robot_Left() { digitalWrite(MotorLeft[0],1); digitalWrite(MotorLeft[1],0); digitalWrite(MotorRight[0],1); digitalWrite(MotorRight[1],0); } void Robot_Right() { digitalWrite(MotorLeft[0],0); digitalWrite(MotorLeft[1],1); digitalWrite(MotorRight[0],0); digitalWrite(MotorRight[1],1); }
