```
public class AutochangerTwoTrucks
extends MobileItem
implements org.lsst.ccs.framework.ClearAlertHandler
```
This is a model for autochanger trucks. Autochanger trucks move a filter from STANDBY position to ONLINE position or HANDOFF position. ONLINE position is just in front of the focal front. STANDBY position is where an exchange can be done with the carousel. HANDOFF position is a position an exchange can be done with the loader. The trucks are moved by 2 controllers, a master and a slave. Each controller has an absolute encoder.
