Introduction and Objectives
In Spring 2013, I worked with 3 people as a team in my Engineering 1182.01 class to develop an energy efficient Advanced Energy Vehicle. I was the Operations Specialist in the group and my job was to make sure the entire designing and developing progress go smooth without any trouble. My job was also to develop a systematic plan for the design process to meet the requirement given by the instructor. My primary role was the vehicle engineer. I am responsible to build the entire vehicle as well as repairing, fixing and also improving.
The objective of the project was to develop an energy efficient Advanced Energy Vehicle. The AEV will be tested on a track provided by the instructor. The AEV had to start at the end of the monorail track system and travels along the rail system. Then, the AEV will stop for 4 seconds 12 feet from the starting point and then travels slowly to tag the Caboose car which is 3 feet away from the stop. Then, the AEV will bring the Caboose back to the original place where the AEV first stopped. Throughout the journey, the team has to manage the energy consumption of the AEV to be as efficient as possible.
The first part of the project was to design the AEV prototype. Every member in the group had to come up with its own unique AEV design and fulfill every attributes given by the instructor. The design had to be compact, well balanced and most importantly, light weight for efficiency. Pictures below show some early stages of design process which includes the preliminary design of our AEV prototype.

During the developing process, several tests had been conducted on the AEV to determine the efficiency of the AEV. The data collected from the tests were then observed and analyzed. After, changes will be made on the AEV to improve its efficiency and performances after having meetings and discussions among group members.
Attachments below are some pictures of our prototype and sample lab reports produced by the lab team for the development process. The attachments contain tables and data of the total energy consumed by our AEV prototype.

Final Test Run
Finally, on the last day of the ENGR 1182.01 course, every lab team participated in the class will run it’s final design prototype of AEV to be evaluated. The AEV vehicle designed by the team was able to run on track smoothly and met all the requirements provided by the instructor. The lab team had successfully obtained full credit 50 points out of 50 points on the evaluation for the test run of this project.
Video below shows the test run evaluation of the AEV prototype designed by the team.
Conclusion and Reflections
In the process of completing this project, the group had to have group meeting at least 3 times a week in order to make sure everything functions smoothly. A lot of teamwork, compromise, tolerance and understanding were needed in this project in order to be successful. Works were assigned fairly among every members and all the members had to finish their job in the given amount of time. The overall experience working together as a team was enjoyable and challenging.
Finally, for the final evaluation day of AEV project, i was assigned to produce the AEV poster by myself for the group. The file attached below is the poster i made for my group and it contains detailed information about every part of the AEV project.
