Work attachment mechanism/work attachment fixture

A system for mechanically and electrically coupling two bodies, comprising:

• a first body comprising a work attachment mechanism including first type spline connecting means selectively located thereon;
• a second body comprising a work attachment fixture, second type spline connecting means positioned thereon to mate with said first type spline connecting means;
• first type alignment mean exteriorally located on said first body for berthing with said second body;
• second type alignment means exteriorally located on said second body for receiving said first type alignment means;
• said second type spline connecting means including a threaded bolt member having a captured nut member located thereon which can translate up and down the bolt but is constrained from rotation thereabout;
• said nut member having a mounting surface;
• at least one first type electrical connector located on said mounting surface for translating to and from said first body;
• at least one complementary second type electrical connector on said first body for mating with said at least one first type electrical connector on the mounting surface of said nut member,
• whereby when said first type spline connecting means mates with said second type connecting means and is driven, both said spline connecting means lock together and said nut member translates up the threaded bolt member carrying said first type electrical connector up to said complementary second type connector for interconnection therewith;
• and
• said first type alignment means comprises a set of roller members located at the side of said first body and said second type alignment means comprises a set of members at the side of said second body having complementary seating surfaces for said roller member.
