Autonom dryckesautomat
Sammanfattning: Since the 1970s the technology within autonomous systemshas been a fast-growing subject, the main reasons beingan increased interest in automation and decreased pricesof sensors and hardware components.There is a wide range of different complexities withindifferent autonomous systems, but this thesis will contributeto an understanding of the basic principles in an autonomoussystem and its components. This is made by constructingan autonomous beverage dispenser that will fill a glass, regardlessof its size, with a certain level of liquid. The purposeof this thesis is therefore to construct a demonstratorthat illustrates how individual components can create anautonomous system.To make it possible, an ultrasonic sensor and a peristalticpump will fill the glass with a certain level of liquid.Another ultrasonic sensor together with a linear actuatorare used to make the system adaptable to different sizesof glasses. With this setup and combining them through amicrocontroller the two modules will act as an autonomoussystem.The performance of the demonstrator was evaluated bymeasuring the errors of the registered liquid level in the differentglasses. Two other experiments were conducted, buton each module individually. The experiments conductedon this system showed results that were within the scope,but there are future improvements that can be made andexpansions to support the knowledge of autonomous systemseven more.
