An Automatic multi-tasking chemical spraying robot is an assembly of multiple tools with various kinds of sensors. Tools and sensors are controlled by microcontroller and microspores. By using mobile remote or voice commands robot operates. Microcontroller converts the voice commands and remote commands into untestable language of tools. Humidity sensor, temperature sensors are inside the sensor box and both work for detecting the humidity and temperature respectively. Tool box consist of camera, DC motor, chemical sprayer, color sprayer and wheels which help to monitoring, controlling and running the robot. Tank is given for filling the chemical of color. As per requirement of chemical spraying sprayer will active with the help of microcontroller and it will start spraying the chemical. Power supply is for giving the potential to robot.
