I'll guess...

Using mtx...

mtx -f /dev/sg<robotic control device> load <slot number> /dev/<tape device>

You'll have a generic scsi interface to the robotic mechanism
and a SCSI tape device (possibly more than one depending on the unit).

Unloading is similar, you unload to an empty tape slot.

mtx -f /dev/sg/<robotic control device> unload <slot number> /dev/<tape device>

You can get a status using:

mtx -f /dev/sg<robotic control device> status

and there's an inquiry and inventory commands (intead of status above).
