Silicon Valley Conducts Successful X-SCAV Flight Test
On September 29, 2009, Carnegie Mellon Silicon Valley, in collaboration
with NASA Ames Research Center, successfully conducted its first series
of flight tests of an 20-foot wingspan unmanned aerial vehicle (UAV)
called the eXperimental Sensor Controlled Aerial Vehicle (X-SCAV) at
Crows Landing, CA. The X-SCAV, which can support up to 50kg of
payload, is the latest result of ongoing collaboration between the NASA
Ames Research Center and the Carnegie Mellon Innovations Laboratory. Carnegie Mellon scientists Ritchie Lee, Yoo-Hsiu Yeh, and Khalid Al-Ali
worked with NASA Ames Research Center scientists on the platform for
this unique unmanned aerial system designed to carry large payloads for
short range deployment.
The X-SCAV is a small ultra-low-cost unmanned vehicle testbed used for
experimental control systems research, development, and
experimentation. The X-SCAV is unique in its class, providing ample
carrying capacity that rivals large UAVs but at a fraction of the cost
and complexity. The XSCAV uses the NASA Reflection Architecture, a
central component-based plug-and-play software infrastructure. This
successful series of flights paves the way for continued X-SCAV flights
at Moffett Airfield, demonstrates the operational status of the
platform to support control system research experiments, and
demonstrates agile concepts for robust low-cost UAV design. The X-SCAV
is built on a commercial airframe manufactured by Bill Hempel.
"The X-SCAV platform is unique in its size and cost versus carrying
capacity. Very few UAVs at this size and price point can support the
amount of payload capacity that this airframe can support. In support
of disaster response such as wildfire response, this aircraft has the
advantage of being able to be deployed and retrieved on-site, which
obviates the need for complex FAA approvals that hampers large UAV
deployments," explained Corey Ippolito, the Project Lead for the team,
and a NASA Ames Scientist who also just started his Ph.D. in Electrical and Computer Engineering at Carnegie Mellon.
Lee, Yeh and Al-Ali from the Carnegie Mellon Innovations Laboratory
(CMIL), worked together on the design and construction of the vehicle. Ritchie Lee, who served as the Systems Engineering Lead for the team,
describes how his research involved converting a remote-controlled (RC)
aircraft kit into a UAV. "Our work focuses on developing flexible
software and hardware platforms that optimize the scientific return of
a payload sensor by adjusting parameters such as flight path and flight
controllers. The X-SCAV was developed as a testbed for this research
and others. This successful flight test, in remote-control mode, marks
the aircraft's first flight, and is validation of the design and
implementation of the airframe and avionics."
CMIL, located at Carnegie Mellon Silicon Valley, has established itself
as one of the world's leading ground and aerospace technology research
centers since its founding in 2003. CMIL focuses on identifying,
researching, testing, and maturing forward-looking ground and aerospace
technologies with applications to mobile vehicles. Leveraging its
location at the NASA Ames Research Center, CMIL brings together the
best and brightest aerospace research professionals from both Carnegie
Mellon and NASA to explore new possibilities for micro vehicle
platforms, aircraft, spacecraft, and associated technologies. Dr.
Khalid Al-Ali, Director of CMIL, serves as Principal Investigator for
this on-going project. "This collaboration is a clear example of the
long list of CMIL successes, where Carnegie Mellon innovation is
coupled with NASA resources, producing work with significant impact,"
says Al-Ali.
