Indoor Mobile Robot Localization



The Robotics Institute released a
report recently titled Parrots:
A Range Measuring Sensor Network (PDF format) that describes a
wireless sensor network that can be used for localization by indoor
mobile robots. The network consists of nodes, called Parrots,
that measure the range to other nodes using ultrasonic sensors. Each
node includes a 16bit microcontroller, a wireless link, and a sensor
board with 4 ultrasonic sensor arrays. When lots of Parrots are placed
in an area, they automatically form a multi-hop ad-hoc wireless network.
The robot carries a Parrot node as well, allowing the network to accurately
map the location of the robot as it moves through the area. This research
was done by the CMU Field Robotics
Center.
