Abstract

This paper presents an engineering technology senior project: radio-controlled robot lawnmower. The lawnmower can go forward and reverse. It can also turn around. The speed of the lawnmower is comparable to a push lawnmower.

This project involved use of the student’s knowledge acquired from many major courses, which included Computer Assisted Drafting and Design (CADD), machine shop, strength and materials, electrical circuit analysis, electronics, electrical machines, and instrumentation and controls.

Introduction

At Middle Tennessee State University (MTSU), engineering technology students must take a project course in their senior year. In this course, engineering situations are solved by experimental means. Student must have experimental approach, gather data, interpret results, and prepare a formal technical written report and an oral presentation.

For the electro-mechanical engineering technology students at MTSU, most of their senior projects involve both electrical/electronics work and mechanical work. In the past years, many excellent projects were completed. Some of the projects were presented at professional conferences [1] [2]. Recently, developing a remote controlled robot lawnmower was selected as an electro-mechanical senior project. In this project, a radio-controlled lawnmower was designed, built, and tested. Figure 1 is the picture of the lawnmower.

Mowing lawn is less than fun for many people, especially if they have allergies or physical limitations. A ride mower requires a driver to ride on the mower. To operate a push mower, a person must walk and push behind the machine. Cutting grass is a good exercise, but not a lot of people like to do it in hot humid summer. It has been many people’s dream that they can stay in shadow or sit on a porch to operate a lawnmower. The remote controlled lawnmower developed in this project made the wish almost true.
