Robot Arm Design for Coffee Maker Arduino


Coffee enthusiasts span a diverse demographic, transcending age and gender boundaries. While historically associated with a simple enjoyment of a cup of coffee to unwind, the coffee culture is undergoing a transformative shift influenced by changes in lifestyle, blending seamlessly with Western influences. In Indonesia, a country with a significant coffee following, the marketing landscape has evolved to include diverse approaches, with coffee cafes serving as a prime example. These cafes, characterized by modern, luxurious, ancient, or unique designs, not only offer a delightful taste but also curate an atmosphere to attract patrons.

Coffee consumption is influenced by factors such as the type of coffee, method of serving, and location. The method of serving varies based on the market and location, with manual brewing often associated with hangout spots in malls, while machine-served coffee finds its place in airports, supermarkets, and stations.

Innovation in the coffee experience is becoming increasingly apparent, and one intriguing avenue is the integration of robotics. Robots, defined as systematically designed tools from various scientific fields, are now making their mark in coffee making. The robotics technique involves hardware elements like microcontrollers, designs, input, and output, alongside software elements encompassing firmware and programs. The use of robotic arms in this context, designed systematically and mathematically, promises precise and balanced movements, especially when deployed in sophisticated industrial settings.

The evolution of Arduino, a microcontroller developed by Hernando Barragan, has facilitated advancements in robotics. Arduino, aiming to simplify design and interaction, has different series with varying capacities and functions. The widely utilized Arduino Uno, equipped with 14 digital pins and 6 analog pins, stands out for its familiarity and stability, making it a preferred choice for research endeavors.Robotic baristas streamline the coffee-making process through automated precision. The operational sequence involves:
