6、-Obb-ENGL 1995 Ob95534 0002099 3bL m Foreword Space Automation and Robotics has been identi- fied as an important area for precursor and human missions that will benefit from guides and stan- dardization. As the field continues to grow, stan- dardization of the terminology associated with this area

7、becomes desirable. This AIAA Standard Vocabulary for Space Au- tomation and Robotics has been prepared under the auspices of the American Institute of Aero- nautics and Astronautics Standards Program. Wherever possible, definitions in this vocabulary conform to those used by the National Aeronau- ti

8、cs and Space Administration (NASA), the Ameri- can Society of Mechanical Engineers (ASME), the Institute of Electrical and Electronics Engi- neers (IEEE), the American Society of Civil Engi- neers (ASCE), and the European Space Agency (ESA).

35、old-site so that, when the other arm attempts to extract an ORU, the reaction forces do not in undesir- able motions. standard - The consistent use of a specific approach (e.g., hardware, software, interface, configuration, etc.) to perform a given function. standard end effector (SEE) - Relative to

36、 the Space Shuttle RMS, the Standard End Ef- fector (SEE) is an interface and locking device on the end of the RMS arm that provides align- ment and mechanical attachment (grapple) for the transportation of objects, including a robot, when operating from the Shuttle payload bay. The SEE mates with t

Remote Task Environment active compliance - The property of compli- ance, as provided through force sensing and

42、feedback control of the robot, rather than pas- sive mechanical means. (See center of com- pliance, compliance, passive compli- ance, remote center of compliance.) align - To place an object such that its position and orientation correspond with a reference frame centered on a feature of another obj

43、ect, or to another specified reference frame, without moving the object from its current location (.e., through a combination of rotations of the object). alignment guide - A device used to provide increased position and orientation tolerances when mating two objects. Guide mechanisms can be externa

44、l to the objects or an integral part of the objects configuration. attach - To join one complementary object to another object (or feature), to make a physical connection (e.g., seating a tool on a fastener, or a fastener in a complementary opening); attach implies the presence of complementary shap

47、ector. center of compliance - For an object gripped by a compliant robot, the point, refer- enced to a gripper-fixed frame, about which that object tends to rotate when acted on by external forces. The location of this point, relative to the points of contact made during constrained mo- tion, is oft

48、en important since it can determine whether or not the positioning action will suc- ceed. (See active compliance, compli- ance, passive compliance, remote cen- ter of compliance). coarse alignment guide - A device or de- sign geometry (e.g., cones, tapers, chamfers) that provides increased tolerance

49、 on approach between mating objects. The guide forces the two objects into a specific position and orienta- tion relative to one another. compliance - The property of a robotic system that allows it to accommodate (Le., control or limit) external forces arising from contact with other objects in its working environment. For example, because the robot path-following accu- racy is limited by sensing and tolerance uncer- tainties, an attempt to position an object roboti- cally, when one or more degrees of freedom of movement are constrained through contact, would result in high forces
