Whiteboard Erasing Robot using Arduino
My entry for the Microcontroller contest is a whiteboard cleaning robot. The goal of this project was to create a robot which could erase written text on a whiteboard completely autonomously, i.e. no human interface. The processes involved in this project included devising a method for the robot to search a whiteboard for text, designing a way to physically move a robot to the text, and enabling a robot to erase the text.
Step 1: Parts/System Break Down
This project is made up of two main sections. The first section is the actual robot. The robot in theory is somewhat simple. It consists of a base with two wheels which rides on a whiteboard track. The base design allows the robot to cover the entire x-axis of the whiteboard. To move on the y-axis, the robot uses linear sliders to move an arm up and down. Attached to the end of the arm is a dry-eraser that does the actual erasing.
Building the robot is not hard. It just consists of 2 motors which each respectively drive 2 small VEX wheels.
Step 2: Computer Vision
*The code that is attached is a basic proof of concept code. It shows how the eraser would move to the text, no matter where it is on the whiteboard. Move your mouse to simulate where the text is written. In order to use the code, you need a copy of RoboRealm. The standard cost is $89, or you can download a 30-day free trial at http://www.roborealm.com/registration/index.php
