Project Description: The Land Vehicle for Education, or LVE, is a vehicular robotic platform that is connected to the Modular Student Attachment (MSA). This project was originally under the name of the Land Vehicle series but has since shifted focus to developing an educational device for Mechanical Engineering Freshmen of the incoming 2013 class. This project is designed to teach Mechanical Engineering principles and design concepts to the students by incorporating various components of the MSA, which they will design, model, manufacture and assemble. The design and production of the LVE is divided into three groups: Chassis/Power, Controls, and MSA.

Problem Statement: Create a vehicular robotic platform that can be attached to an MSA. The design must be cost effective and have the ability to be produced in large quantities. The MSA must also be developed to teach various aspects of the Mechanical Engineering.

Mission Profile: A Typical LVE Run CycleThe LVE will travel across a classroom, pick up a foam block off of a shelf. The LVE will then travel back across the room and place the block on another shelf. This

process will be repeated 2 additional time, for a total of 3 moved blocks. The following charts describe the movements of the LVE during these repetitions.

Customer Needs1. LVE must be able to move about freely through the

use of wireless controls.2. LVE must be cost effective enough to be produced

in larger quantities. 3. LVE must be well constructed and able to withstand

repeated use.4. LVE must be reliable, requiring minimal repairs and

debugging.5. MSA must provide educational value to freshman

Mechanical Engineering students.6. MSA must incorporate design aspects from

preexisting courses (Engineering Design Graphics & Materials Processing).

7. MSA must be complex enough to support small groups of students working at once.

8. MSA must build off of preexisting knowledge and be easily learned by students.

In order to meet the mass production cost requirements,the following component breakdown was used:

10 LVEs (chassis and controls) 10 MSA control boards 30 MSA assemblies

This breakdown provides enough LVEs and controls to support one single class of students, though there are enough MSA assemblies to support an entire quarter worth of students. Since the MSA was designed to be easily removedfrom the chassis, the LVEs can easily be used throughout multiple class sessions within the same quarter. The individual MSA assemblies will allow the students to keep their design intact from one class to another, reducing thebreakdown and start-up time for each class session.
