AEV DESIGN PROCESS
◼Efficiency
◼ Light weight and energy efficient
◼ Low cost
◼Simplicity/Functionality of design
◼Incorporate different aspects of
each member's design
Initial Design
Intermediate 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 -- $203.98
◼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.
