SURVEYOR is a pre-study (6-month) project aimed at improving the work space in foundries by using a
better ventilation surveying approach. While indoor ventilation is critical due to the health and
safety concerns associated with ambient air quality, current surveying techniques are overly
simplistic and do not provide plant operators and occupational health specialists with accurate
information regarding indoor airflow.

We present a system that addresses the need for better ventilation surveying techniques.
Rather than relying on sporadic measurements and simplistic models, the proof-of-concept
system in SURVEYOR addresses ventilation surveying using a mobile robot, static sensing
nodes and advanced statistical modelling algorithms. The robot and the sensing nodes provide
complementary view s of the airflow patterns inside the foundry at different temporal and
spatial resolutions. The “ventilation maps” produced by SURVEYOR are statistical models that
predict the airflow conditions (w ind speed and directions) over the entire foundry. Ventilation
studies at such level of detail are not produced by current characterization techniques.
SURVEYOR w ill be developed at Örebro University, which is a lead research institution in
environmental-monitoring robotics. Johnson Metall, Scandinavia’s largest manufacturer of
bronze bearings, and Global Castings Guldsmedshyttan, a global supplier of heavy cast-based
components for the w ind pow er industry w ill support the project from the standpoint of an

SURVEYOR is funded by the strategic innovation programme STRIM (Strategic innovation programme for the Swedish mining and metal producing industry), which is part of a joint investment in strategic innovation areas (SIP) by Vinnova, Formas and the Swedish Energy Agency.
