Abstract: In this paper a control system is designed to operate a Humanoid Robot “Bioloid Premium” using DTMF (Dual-Tone Multiple- Frequency) technology of mobile phones for long range operations. The mobile phone with the operator acts as a transmitter and the one attached to the Robot acts as a receiver and hence no additional communication devices are required. The operator calls the mobile installed in the humanoid Robot which gets activated through auto answering mode. In the course of a call, if any button is pressed, a DTMF tone corresponding to the button pressed is heard at the other end of the call. The Humanoid Robot perceives this DTMF tone with the help of the phone placed on it. The received tone is processed by the Arduino microcontroller with the help of DTMF decoder. The decoder decodes the DTMF tone into its equivalent binary digit and the same is sent to the microcontroller. The microcontroller is programmed to take a decision for any given input and outputs its decision to the CM-530 controller through a Zigbee wireless interface. The output decision of the CM-530 processor is sent to motor driver in order to control the servo motors in required direction for human like moves. Auto answering video calling is done in order to control the humanoid very easily and precisely. Experiment based on the DTMF has been carried out which can be implemented in the humanoid robot for various applications like security or safety, defence, assistance in medical and environmental hazards and other humanitarian services.
