Research funded by the U.S. Poultry & Egg Association studied the intelligent automated transfer of live birds to the shackle line.
-> The development of an overhead conveyor for transporting a number of equally spaced graspers, each of which consists of a pair of rotating hands, as well as the mechanism that grasps a bird from the moving conveyor. The mechanical hands continuously cradle the bird for the consequent processes.
-> The development of a vision-guided magnetic actuator to correct the orientation of the grasped bird, as well as improvements on the vision system.
-> A design to provide a means to render a mechanically cradled bird insensitive to pain before shackling its feet and inverting its body.
