This workshop covers various concepts of mobile communication and microcontroller programming, necessary for the development of a mobile controlled robot. DTMF stands for “Dual tone multiple frequency”. We will be using a dedicated modem/mobile at the receiver module i.e. with the robot it self and send the commands using DTMF tones as per the required actions. Conventionally, Wireless-controlled robots use radio control, which have the drawbacks of limited working range, limited frequency range and the limited control. Use of a mobile phone for robotic control can overcome these limitations. Students would develop a robot that can be controlled by calling the mobile phone placed on the Robot and pressing the keys on their mobile phone.
