Abstract:

Several end effector systems which regulate and distribute the loads generated in
handling structural elements during space assembly operations have been designed
and an and an evaluation of the concepts developed.  Current end effector designs
transmit concentrated loads to the structural members handled.  Current end effector
designs transmit concentrated loads to the structural members handled.  This may
not be acceptable for use in the assembly of structures in space, as the structural
elements may well be susceptible to damange resulting from concentracted loads induced
by end effectors or other handling mechanisms.  Therefore the feasibility of "soft
contact" end effectors and handling mechanisms has been determined.  Some preliminary
concepts developed under Phase l include end effectors with inflatable jaw faces,
where contact area is increased and contact pressure can be preset to an acceptable
level; end effectors which interface with preexisting attach points on the structural
element to be handled; inflatable slings and cradles for handling of large panels,
etc.
	The results of Phase l would identify those concepts which warrant further development
during Phase II, which should include development and testing of the candidate end
effector concepts and handling mechanism concepts as well as more detailed analysis.
