Two manipulators share a same global reference coordinate. The mission of Manipulator 1 is to position the fixed part of connection fittings and screw the bolts on it. Visual computing provides the approximately position for the end-effector of Manipulator 2, after which The Manipulator 2 carries the removable part of connection fittings to this position. Then, the assembly task could be completed with the posture of the Manipulator 2 adjusted following the guidance by force-position control.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Findings<\/jats:title>\n<jats:p>The dual manipulator system can position the target under different illumination conditions and complete fast assembly of connect fittings in 110-kV substation.

The system is able to achieve the connection fittings assembly task under energized simulation experimental system. Unlike other peg-in-hole assembly strategy, it does not require high stability of manipulator or plane contact surface around the hole.<\/jats:p>\n<\/jats:sec>","DOI":"10.1108\/ir-11-2016-0320","type":"journal-article","created":{"date-parts":[[2017,5,4]],"date-time":"2017-05-04T05:48:43Z","timestamp":1493876923000},"page":"479-490","source":"Crossref","is-referenced-by-count":6,"title":["Dual
