Design Requirements• Structure and Payload

• Flight Mode

• Power and Propulsion

• Control

• Mission

• Cost

• Deliverables

Es 100 group 2 MAV project04/18/23

Structure and Payload• There is no size restriction.

• A quick mount should be provided for a 20-g micro DVR.

• The maximum weight of the vehicle including payload should be 450 g.

Es 100 group 2 MAV project04/18/23

Flight Mode

• Fixed wing, rotary wing, flapping wing, hovercraft, lighter-than-air, or any innovation is allowed.

• Ground takeoff and landing is required

Es 100 group 2 MAV project04/18/23

Power and Propulsion

• The use of internal combustion engines or open flame hot-air is prohibited.

• The vehicle must be able to fly for at least 5 minutes without replenishing or recharging its energy source.

Es 100 group 2 MAV project04/18/23

Control

• The vehicle must be controlled by a 2.4G Hz radio transmitter

• Must operate in a 100’x50’x30’ indoor/outdoor space.

Es 100 group 2 MAV project04/18/23

Mission

• Endurance - fly as many figure 8 paths around two pylons separated by 50’ in five minutes.

• Precision flight – survey a 100’x50’ground area and acquire a legible image of each of the four 1’x1’ targets.

Es 100 group 2 MAV project04/18/23

Cost• Total as-built replacement cost of the

vehicle and the trainer must be less than $250.

• The cost must be broken down in a Bill of Materials (BOM), in which the Fair Market Value (FMV) of each component must be listed along with the part number, description, and quantity.

Deliverables• The MAV.

• The preliminary design presentation (PowerPoint slide file)

• The final design presentation (PowerPoint slide file)

• The final printed design report

Es 100 group 2 MAV project04/18/23

Design Details• 3-channel GWS Slow Stick kit adopted as basic

platform

• Using recommended propulsion / control kit (Dynam brushless motor, 18A ESC, servos)

• Using recommended power source

• 8 x 4 propeller or similar to be used

Es 100 group 2 MAV project04/18/23

Yet To Solve

• LiPo battery charging

• Electrical/electronic component schematic

Procurement – Lessons Learned• Purchase earlier

a) Obtain better pricing on transmitter/ reciever

b) Combine shipping

• Source as many parts as possible through a single supplier

a) Reduce shipping
