Overview Design process Cost efficiency Power efficiency Methods of Improvement Obstacles

AEV DESIGN PROCESS Efficiency Light weight and energy efficient Low cost Simplicity/Functionality of design Incorporate different aspects of each member's design

Initial DesignIntermediate Design

DESIGN OF AEV T shaped base used to house all aspects of AEV Holds Arduino, battery, propellers Reduce parts More stability on turns Pusher configuration for propellers L shaped arm Houses wheels and sensors Stability on track--spreads out weight of base Balance front to back

COST EFFICIENCY Simplistic Design– reduces cost of materials and weight of the AEV Different designs tested– OSWALD Model proved most efficient in cost, weight of AEV, and energy efficiency Bill of Materials Total Cost -- $ Bulk of expense from Arduino and Battery

PERFORMANCE ENERGY Construction of Code Completion of task Base code to retrieve R2D2 and return to starting position Revise code to cut down energy use Examined phase chart of energy consumption More coasting Optimal speed to maximize distance traveled and minimize energy output Final Energy Use: 209 J

METHODS FOR IMPROVING EFFICIENCY Incorporate Celerate Command Start and end with a motorSpeed command to have consisted runs. Gradually accelerate the motors to a higher percentage of power to minimize waste of energy and maximize the effectiveness of the motors. The motors will run for a shorter amount of time. AEV will coast for a longer amount of time saving energy usage.

METHODS FOR IMPROVING EFFICIENCY Optimizing AEV Coasting Allow the AEV to coast as long as possible without reversing the motor to have consisted stops. The longer the AEV is coasting, means less time that the motors are on.

OBSTACLES THE TEAM FACED AEV Stopping at the gate inconsistently Getting rid of brake commands to save energy Connecting the to the R2D2 unit properly Inconsistencies in runs Sensor Issues Having a bad sensor that didn’t connect fully. Connecting the sensors incorrectly.
