Analysis

STONES

When this equipment have been evaluated this will be used to match

curling stones by speed


Next step is to find or invent a machine that can measure the roughness of the running band and give you the curl

STONES

When we have this we can compare stones both on speed and curl and do the matching from that result


Development and testing in progress

Measuring stone positions automatically
