The project is aimed to design a land rover for which, 2D movements can becontrolled using a mobile phone. To practically implement the same, DTMF (Dual Tone Multi Frequency) technology is used where the frequencies of the mobile keypad are decoded, each button on the keypad has unique inputs. By using an ATMEGA IC we can program the outputs for respective inputs. Thus, we can move the robot in all four directions (2-dimensional) using two motors.
