Here is Anbarasi. I have constructed the schematics of the Human following robot. But while compiling the Arduino program, it is not get compiled. It is showing like there is AFMotor: No such file or folder and highlighting this comment "#include<AFMotor.h>"AF What should I do?? My mail id is gdjebaselvianbarasi16@gmail.com
