Our Work

Abstract

The drawing robot is a mobile rover that can replicate user-submitted images on the ground using chalk

Problem Statement

Restaurants and coffee shops often advertise their special menu items on small blackboards to attract customers when they walk by. Our project will be used to substitute or complement other advertising by drawing images on the sidewalk outside the establishment.

Functional Analysis

The box diagram on the left represents the internal mechanism of our robot.

Code Decomposition

The gray box are the pseudocode. The table is the output of our code.

The reason we use g-code is that our robot is similar to a 3d printer, our robot requires coordinates and a judgment of whether the robot is going to print or not to print in the next step. G-code can provide all of that information.

Why do we need to convert from g-code to polar coordinates?

This conversion is required because unlike a 3D printer, our robot cannot move in horizontal positions. So simply providing the coordinate is not enough to control the robot.
