Abstract
This paper introduces a systematic approach to design and implement a Real-time Voice Activated Programmable Multipurpose Robot. The robot’s architecture consists of the following subsystems, namely Electronics subsystem and Software subsystem. Electronics subsystem gets a set of commands from software subsystem and generates control signals for the entire system. Software subsystem which is usually a computer provides easy to use interface for users which may be accepting commands like natural language sentences and translates it to low level commands which could be understood by machine (microcontroller or microprocessor). A voice recording IC APR9600 of non-volatile storage and playback capability is deployed in the system. This IC can be used in visitor guiding mode and patient guiding mode to play the voices stored. APR9600 can store 8 voices as we are using voice recorder IC in random access mode. A photoelectric sensor through opto-coupler is connected to the microcontroller to sense the obstacles in front of the robot and to take appropriate decisions The robot is controlled wirelessly using DTMF Decoder by dual tone multi frequency technique (DTMF). Two cell phones are used here one as transmitter and another as a receiver .The signal from the receiver cell phone headset is given to the IC HT9170B which decodes the dual tones and gives a binary data according to the key pressed in the transmitter cell phone. The receiver cell phone is kept in the robot. First a call is made from a transmitter cell phone. After the call gets activated in the receiver end we can control the robot through the transmitter cell phone
