Here in Mikkeli they have a very interesting optical device that I have seen for the first time. This is a vehicle optical device that I have seen for the first time. They stick some plastic with dots on the tires of the vehicle and then the device reads the positions itself. The device is very tall and at the end it has two arms with cameras on them that read the optics. The whole thing is connected to a computer on which we read what is wrong and what needs to be fixed. The device also has a special lift that we can drive the vehicle onto. The vehicle can be a passenger car or a van.
