  • Electric-controlled operator
    Patent number: 8556318
    Abstract: An electric-controlled operator includes, in part, a first group of grippers and a second group of grippers which are coupled to a base. Grippers in the first group of grippers are adapted to cooperatively grip an object and cooperatively release the object. Grippers in the second group of grippers are adapted to cooperatively grip an object and cooperatively release the object. When the first (or the second) group of grippers cooperatively grips an object, the second (or the first) group of grippers is in a state in which the object is released. The first and second groups of grippers are adapted to put in and take out objects from the same surface of the base thus eliminating the need for turning of the base during the operation.
