GradeMaster9000: Automatic Grading Robot! · 模型 256611
Final Project for Dr. Aaron Becker's ECE 6311 Introduction to Robotics class at University of Houston. Completed By: Andrew Smith Mohak Bhatia Israel Ilagan The projects goal was to create a robot that is capable of recognizing text through optical character recognition code, grade the free response questions (advantage over a "scantron"), and stamp the correct grade on the paper. Be sure to watch the linked YouTube video to see the Grademaster in action, as well as some recommendations we have for future work/improvements! All Printed parts printed with PLA, 3 Layer Wall Thickness, 18% infill. Code and wiring schematic are posted in "Documentation and Code" section, Additional Components Required: - 3X MG946R Servos - HAVIT HV-N5086 Camera and Webcam - 10K Potentiometer - 12V Rocker Switch - Momentary Push Button Switch - ExcelMark Ink Pad for Rubber Stamps 2-1/8" by 3-1/4" - Red - Educational Insights Alphabet Rubber Stamps - Uppercase 5/8" - Male to Male Jumpers - Sparkfun RedBoard (or Arduino Uno) - 6V Battery Source - 11X 2 Hole Mini Nutstrip (https://www.kitbots.com/product.sc;jsessionid=23092BF49296A6834DD0488C8BE2BB4C.p3plqscsfapp002?productId=32&categoryId=1) - 2X 3 Hole Mini Nutstrip (https://www.kitbots.com/product.sc;jsessionid=23092BF49296A6834DD0488C8BE2BB4C.p3plqscsfapp002?productId=33&categoryId=1) - 43X 6-32 Machine Screws - #4 Plastite Screws (https://www.mcmaster.com/92295a106) - Piano Wire to create linkage for Ink Tray - 3/4" PVC Piping to create camera stand (Left to viewer discretion based on webcam selection, we found a camera height of ~30 cm to work well)
