Goal of taskProvide localization and positioning in a mining environment
At three different levels:- Coarse (+/- 20m)- Intermediate (+/- 1m)- Fine (+/- 1cm)
Different levels of accuracy require different types of technology

LTU / Eistec- Intelligent rock bolt- Using Mulle platform- Every rock bolt has its own
IPv6 address and can establish a wireless mesh network in an ad-hoc manner
- Using triangulation i.c.w. multiple rock bolts a localization accuracy of 10cm can be achieved.

High Level Service Architecture (1/2)- RigidBodySensor (6DOF)
- Provides: - position - orientation
- InertialSensor (9DOF)- Provides:
- acceleration (g) - rotation (degrees/s)- magnetometer (uT)
- Data from InertialSensor can be integrated to act as a RigidBodySensor.

High Level Service Architecture (2/2)Combining the strengths of different sensors can increase the robustness and accuracy of the localization solutionSensorFusionService- Subscribes to the data from other RigidBodySensors and
InertialSensors to act as a virtual sensor
