Current Projects
Unmanned Aerial Vehicle Design and Control
In
this project, we are building a team of UAVs with the
goals of studying formation flying, architectures for distributed control, and
methods for reliable control over communication links. All of the aircraft and
automation design has been done by us -- and we fly the vehicles at Moffett
Federal airfield next to NASA Ames. This work is supported by the DARPA Software Enabled Control program.
Flight test results can be seen here. More can be found
in the DragonFly website.
STARMAC project
STARMAC
is an outdoor testbed for testing and validating
multi-agent algorithms and control schemes. It comprises a set of autonomous quadrotor helicopters that can follow prescribed waypoint
trajectories. They are controlled by a central ground station through a
wireless communication link. This link carries GPS correction data and new
waypoint commands up to the flier, and flight data from the fliers to the ground
station. The trajectory generation may be performed by the ground station
computer or on another machine that supplies the waypoints to the ground
station computer. The basic aircraft is the Draganflier
III, an off-the-shelf radio-controlled X4 flyer with onboard stability augmentation.
We have completely replaced all of the manufacturer’s onboard electronics with
our own sensor suite, microcontrollers, bluetooth
wireless device and associated hardware. The current onboard sensor suite
includes a differential-capable GPS unit, an ultrasonic altimeter, and an off-the-shelf
IMU called the 3DM-G for attitude sensing. We currently have a single
autonomous helicopter that is capable of tracking a commanded waypoint
trajectory. The main goal is to have three or four aircraft that are capable of
demonstrating multi-vehicle coordination tasks. Another task is to enable the
aircraft to fly indoors, using vision-based navigation. Visit our website http://cherokee.stanford.edu/~starmac.
