P11211, P11212, P11213 Land Vehicle for Education System Team: Michael Deyhim & Megan Ott 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. Mechanical Engineering Department Mission Profile: A Typical LVE Run Cycle The 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 Needs 1.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.

Since the MSA was designed to be easily removed from 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 the breakdown and start-up time for each class session.
