Automated liquid filling system with a robotic arm conveyor for small scale industries

Automated liquid filling system is a mechatronic system that has the ability to automatically fill number of container(s) with a liquid to a desired level. This paper presents design and development of an automatic filling system, with a robotic arm conveyor for small scale industries. The overall system is developed using robotic arm and Arduino controller. The movement of the robotic arm is managed by gear motors. An IR proximity sensor has been used to sense the presence of the bottle. However, an ultrasonic sensor was used to sense the level of liquid in the bottle. The control of the system is achieved using an Arduino micro-controller, Arduino Mega 2560. The overall system was tested under various conditions and its working was found satisfactory. In future the IR proximity sensor can be replaced by a limit switch to eliminate errors associated with solid state devices and again a solenoid valve may be used instead of electric pump.
