Putting the Robotics in SHARP
2. The Motor Shield Kit and Servos
Servos are the easiest way to start making motion with an Arduino. Even though
they don't turn 360 degrees, you can use them to create all sorts of periodic or
reciprocating motions. In this project, potentiometer values are read in through an
'Analog In' pin. The values are then used to control the position of a servo motor.

To collect temperature, acceleration, and location
data, to trigger a servo at a predetermined
altitude on descent (parachute release on
SHARP-4).
Ardupilot Mega at DIY Drones
$250 kit
Convert any RC airplane into a fully-autonomous UAV!
Just add the ArduPilot Mega autopilot to any RC aircraft and it becomes a fully-programmable flying robot with a
powerful ground station and Mission Planner.
Features include:
Return to Launch with a flick of your RC toggle switch or a mouse click in the graphical Ground Station
Unlimited 3D GPS waypoints
Built-in camera control
Fully-scriptable missions
One-click software load, and easy point-and-click configuration in the powerful Mission Planner. NO programming
required!
Replay recorded missions and analyze all the data with a graphing interface
Supports two-way telemetry with Xbee wireless modules.
Point-and-click waypoint entry or real-time mission commands while the UAV is in the air
Fly with a joystick or gamepad via your PC--no need for RC control!
Built-in failsafe will bring your aircraft home in the case of radio loss
4. Stratospheric Heating
Experiment (SHE)
• SHARP-2 recorded a low external temperature of
-41 °C. SHARP-3 will place both Marathon DL
precision temperature sensors on the outside of
the payload box. One will be covered in aluminum
foil to reflect radiation from the sun and a
comparison of the temperatures recorded will
indicate whether heating is primarily by conduction
or radiation in the stratosphere.
• We can still log temperature inside the payload.
5. Improved Imaging

•
9 gram HD Video Camera!

_mode=1&safe=active
Two 808 #16 Keychain Cameras
will be used to capture HD video
of the Glider’s Release and the
Cut-Down of the Payload.
We can also use the cameras from
SHARP-1/2 (Canon A1200, GoPro
HD Video, Sony etc.)
New compartments will need to
be built. The SPOT Messenger
(GPS) will need to stand vertically.

6. RC Rocket Glider Drop
Glider dropping experience will be gained on
SHARP-3 for a SHARP-4 mission.

The ARCIE II Kit by Edmonds Aerospace
A Boost Rocket Glider
The ARCIE II comes complete with booster pod,
glider, Hitec 3 channel FM transmitter with
rechargeable battery pack, Hitec Feather receiver (w/
matching crystal), rechargeable battery pack (for
receiver), 1 servo and a battery charger that works for
both battery packs.

Wingspan: 18 in.
Equipment Fairing Diameter: 0.98 in.
Weight: Glider, raw parts: 2.3 oz. (approx.)
Glider, built, w/ RC gear: 3.5 oz. (approx.)
Booster + Glider (w/ RC gear, no engine): 5 oz.
(approx.)
Recommended Engines: C11-3, D12-3 and E9-4

“Dream Chaser”
Glider Release by Arduino/Servo inside
the Payload OR by RC Transmitter on
the Ground?
The Quanum R/C
bomb system can
be installed in
minutes and is
triggered by a
spare servo
channel in your
receiver. But we
will probably use
our Arduino
triggered servo as
primary glider
release.

SHARP-3 Jobs We Should DO NOW!
1. Pre-Launch, Launch and Chase Procedures/Checklists need
to be made and tested.
2. SHARP 1 and 2 data analysis – height and speed of
Jetstream in October.
3. Rebuild the Photographic module so that its deeper. No
overlap of UV filter onto the Science module.
4. Build small compartments in the photo and com modules
for the 808 keychain cameras. I have an old broken 808 for
fitting. Two new ones will arrive after the break.
5. Amateur Radio Course - underway
6. Arduino Course – Interested in programing Arduinos? A
quick course will start soon. Then you work/play on your own.
7. We can start cold testing servos almost any time.
8. 3D Modelling Anyone? Inventory? RC Glider and Lifting body
research?

This radio control airplane is
carrying a scale model of X-33 lifting
body and is taking part in NASA
research.
“On 28 October 2010, a team of
British space enthusiasts
launched a paper aeroplane into
space from a helium balloon at
an altitude of 89,591 feet
(27,307.39 m) above the earth’s
surface. The plane had a
wingspan of three feet, was
made of paper straws, covered in
paper and it took a year to
construct. The balloon was
equipped with two cameras and
tracker devices, and both plane
and balloon were retrieved intact
about 100 miles from the launch
site. The project cost £8,000
(approx. $12,700).”

GUINNESS WORLD RECORD FOR HIGHEST
ALTITUDE PAPER AIRPLANE
Max. Altitude SHARP-1 and SHARP-2
(Stratospheric Glider Recovery Area
West of Gladstone)
SHARP-1/2 data analysis is needed. What altitude was
the jet stream? What speeds were reached in the jet
stream? When will SHARP-3 reach the jet stream?
When will it leave the jet stream? We should watch for
these events during the SHARP-3 chase.
Cold tests will need to be run on the
servos to determine if they will work for
a payload cut-down at -60 C.
