So I started to scavenge around for the \u00a0basic materials I would use to build it.<\/p>\n<p>I built the prototype from lots of random junk and added some stepper motors and drivers that would be used to move the gun. Additionally, there was a servo motor added to pull the trigger of the gun, though in the final product, the trigger is electronic, so we can actually fire that with an output from the GPIO pins on the development board.<\/p>\n<p>The below video shows how the turret works and provides a brief outline of the materials used to build it.<\/p>\n<\/div><\/section><\/div>\n<section  class='av_textblock_section av-av_textblock-0366cc7376be6c9e82a3e9cc8987b64f '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><div class='avia-iframe-wrap'><iframe loading=\"lazy\" width=\"1500\" height=\"844\" src=\"https:\/\/www.youtube.com\/embed\/cKjeoYmWycY?feature=oembed\" frameborder=\"0\" allow=\"autoplay; encrypted-media\" allowfullscreen><\/iframe><\/div>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_one_full-6126cab7d8fab8d08143dd2dacdf673c\">\n.flex_column.av-av_one_full-6126cab7d8fab8d08143dd2dacdf673c{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-av_one_full-6126cab7d8fab8d08143dd2dacdf673c av_one_full  avia-builder-el-4  el_after_av_textblock  el_before_av_hr  first flex_column_div av-zero-column-padding  column-top-margin'     ><section  class='av_textblock_section av-av_textblock-0366cc7376be6c9e82a3e9cc8987b64f '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><h1>Hardware:<\/h1>\n<ul>&#8211; Raspberry Pi 3<\/ul>\n<ul>&#8211; EazyDriver stepper motor drivers<\/ul>\n<ul>&#8211; 2 x NEMA 17 stepper motors<\/ul>\n<ul>&#8211; 1 x Roll of drive belt matching the stepper motors<\/ul>\n<p>The Raspberry Pi is running a Python script to read commands coming from AWS and when it receives new data, it parses this and feed the information to the desired control methods.<\/p>\n<p>Control messages are sent to AWS using an android application that contains a virtual joystick.
