The intended use of our robotic system is for an arm to draw lines on a piece of paper coming from a Python GUI as user input. It also incorporates horizontal, vertical and diagonal lines. The SD-Card bot was built with 2 servo motors and an Arduino nano. It takes in three inputs mainly in terms of buttons; these include the start and pause buttons. The other user input is the sd card which takes a moves.txt file containing all the G-code commands from the graphic user interface. One accomplishment was the GUI interface which allowed the user to use a sketchpad to draw the robotic arm output. This was very intriguing as we were still able to pass G-code commands through. We also created a PCB to handle the dcpwr module which was impressive given our knowledge from JD1. A main challenge was getting the Arduino Nano to understand the parsed G-code in the .txt file. Sometimes, the robotic arm system wasn't able to draw a straight line or 4 inches per second due to issues with the .txt->parser->servos communication.
