  • Automated Vending Machine

    Submitted by Peter Nines, New Jersey, USA

         The goal is to develop a robotic application where users place an order on a website. The order info is uploaded to a cloud database. The Stepper Bee Plus is connected to a Windows 10 computer which polls the cloud database, downloads order info, and processes the orders.

    The Stepper Bee Plus & stepper motors are controlled by a Microsoft Excel VBA application. Excel may not be an industry standard tool for controlling robots, but it has other capabilities that make it a great business tool. The app stores metrics on the number of vending cycles & steps, direction of the motor at any given part of the cycle, etc. The app will be extended to include metrics and charts pertaining to the products and inventory control.
    There were issues with the silo. The wood parts were assembled in the less humid winter months. As spring and summer came along, with increased humidity, some sanding was required to ensure that the product boxes would dispense without getting stuck. Wood partitions that separated the products were replaced with Plexiglas.
    I experimented with stepper motors of different sizes to find the right torque to dispense the products, which are stacked on each other. There’s certainly room for improved design.

    A belt drive moves the dispenser to the product silo. The screw-drive dispenser pushes the selected item out of the silo.
