this robot is IC L293D to control the wheels. Here each dc
motor takes their control over their respective wheel.
Robot has some sensors like PIR, temperature, vibration,
sound. PIR sensor is kept to detect the human interruption.
Temperature sensor is used to sense the temperature in a new
environment. Vibration sensor is used to detect the vibrations
in an unidentified object. Sound sensor is used to capture
sound from different environment. These sensed collections of
data are sent to a human operator.
Wireless charging system is implemented here to avoid the
replacement of battery everytime. It will decrease the cost and
increase the efficiency of the robot. From a pair of rechargable
batteries, power supply is given to all the modules.
