The main purpose of this research work is to propose a suitable IoT-based control method for a dosa-making robot. There are several IoT-based control methods: virtual reality, mobile phone, website, joystick, etc. We have used mobile phone-based control of cleaning, dosa batter flow, oil flow, speed and temperature using IoT, in the dosa-making robot. A simple android-based app was developed so that the users can easily control the robot. The robot is automated using the programmable logic controller. The mechanism used for heating is a slip ring mechanism in order to get rid of the need for gas or fire. The experiments and results show that mobile phone-based control of cleaning, dosa batter flow, oil flow, speed and temperature using IoT is one of the simple and easiest way to control the dosa-making robots.
