An apparatus and method is provided for loading objects having a first degree of hardness onto a tray having a different degree of hardness where sliding contact between the objects and the tray would cause damage. The tray loading is accomplished by engaging and holding objects in a carrier. The carrier carries the objects to a position over the tray and lowers the objects onto the tray surface, avoiding abrasion between the objects and the tray. The carrier includes sensors for verifying the presence of the objects.
