9、tion for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established

10、has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Th

The committ

15、ee responsible for this document is Technical Committee ISO/TC 299, Robots and robotic devices. This Technical Specification is relevant only in conjunction with the safety requirements for collaborative industrial robot operation described in ISO 10218-1 and ISO 10218-2.iv ISO 2016 All rights reser

16、ved ISO/TS 15066:2016(E) Introduction The objective of collaborative robots is to combine the repetitive performance of robots with the individual skills and ability of people. People have an excellent capability for solving imprecise exercises; robots exhibit precision, power and endurance. To achi

17、eve safety, robotic applications traditionally exclude operator access to the operations area while the robot is active. Therefore, a variety of operations requiring human intervention often cannot be automated using robot systems. This Technical Specification provides guidance for collaborative rob

18、ot operation where a robot system and people share the same workspace. In such operations, the integrity of the safety-related control system is of major importance, particularly when process parameters such as speed and force are being controlled. A comprehensive risk assessment is required to asse

19、ss not only the robot system itself, but also the environment in which it is placed, i.e. the workplace. When implementing applications in which people and robot systems collaborate, ergonomic advantages can also result, e.g. improvements of worker posture. This Technical Specification supplements a

20、nd supports the industrial robot safety standards ISO 10218-1 and ISO 10218-2, and provides additional guidance on the identified operational functions for collaborative robots. The collaborative operations described in this Technical Specification are dependent upon the use of robots meeting the re

21、quirements of ISO 10218-1 and their integration meeting the requirements of ISO 10218-2. NOTE Collaborative operation is a developing field. The values for power and force limiting stated in this Technical Specification are expected to evolve in future editions. ISO 2016 All rights reserved v Robots

33、O 10218-2:2011 describes safety requirements for the integration of industrial robots and robot systems, including collaborative robot systems. The operational characteristics of collaborative robot systems are significantly different from those of traditional robot system installations and other ma

34、chines and equipment. In collaborative robot operations, operators can work in close proximity to the robot system while power to the robots actuators is available, and physical contact between an operator and the robot system can occur within a collaborative workspace. See Figure 1.2 ISO 2016 All r

35、ights reserved ISO/TS 15066:2016(E) Key 1 operating space 2 collaborative workspace Figure 1 Example of a collaborative workspace Any collaborative robot system design requires protective measures to ensure the operators safety at all times during collaborative robot operation. A risk assessment is

36、necessary to identify the hazards and estimate the risks associated with a collaborative robot system application so that proper risk reduction measures can be selected. 4.2 Collaborative application design A key process in the design of the collaborative robot system and the associated cell layout

37、is the elimination of hazards and reduction of risks, and can include or influence the design of the working environment. The following factors shall be taken into consideration: a) the established limits (three dimensional) of the collaborative workspace; b) collaborative workspace, access and clea

38、rance: 1) delineation of the restricted space and collaborative workspaces; 2) influences on the collaborative workspace (e.g. material storage, work flow requirements, obstacles); 3) the need for clearances around obstacles such as fixtures, equipment and building supports; 4) accessibility for ope

39、rators; 5) the intended and reasonably foreseeable contact(s) between portions of the robot system and an operator; 6) access routes (e.g. paths taken by operators, material movement to the collaborative workspace); 7) hazards associated with slips, trips and falls (e.g. cable trays, cables, uneven

40、surfaces, carts); c) ergonomics and human interface with equipment: 1) clarity of controls; 2) possible stress, fatigue, or lack of concentration arising from the collaborative operation; 3) error or misuse (intentional or unintentional) by operator; 4) possible reflex behaviour of operator to opera

41、tion of the robot system and related equipment; 5) required training level and skills of the operator; ISO 2016 All rights reserved 3 ISO/TS 15066:2016(E) 6) acceptable biomechanical limits under intended operation and reasonably foreseeable misuse; 7) potential consequences of single or repetitive

42、contacts; d) use limits: 1) description of the tasks including the required training and skills of an operator; 2) identification of persons (groups) with access to the collaborative robot system; 3) potential intended and unintended contact situations; 4) restriction of access to authorized operato

43、rs only; e) transitions (time limits): 1) starting and ending of collaborative operation; 2) transitions from collaborative operations to other types of operation. 4.3 Hazar d identificati on and risk assessment 4.3.1 General The integrator shall conduct a risk assessment for the collaborative opera

44、tion as described in ISO 10218-2:2011, 4.3. Special consideration concerning potential intended or reasonably foreseeable unintended contact situations between an operator and the robot system, as well as the expected accessibility of an operator to interact in the collaborative workspace, shall be

45、taken into account. The user should participate in the risk assessment and design of the workspace. The integrator is responsible for coordinating this participation and for selecting the appropriate robot system components based on the requirements of the application. 4.3.2 Hazar d identification T

46、he list of significant hazards for robot and robot systems contained in ISO 10218-2:2011, Annex A, is the result of hazard identification carried out as described in ISO 12100. Additional hazards (e.g. fumes, gases, chemicals and hot materials) can be created by the specific collaborative applicatio

47、ns (e.g. welding, assembly, grinding, or milling). These hazards shall be addressed on an individual basis through a risk assessment for the specific collaborative application. The hazard identification process shall consider the following as a minimum: a) robot related hazards, including: 1) robot

48、characteristics (e.g. load, speed, force, momentum, torque, power, geometry, surface shape and material); 2) quasi-static contact conditions in the robot; 3) operator location with respect to proximity of the robot (e.g. working under the robot) ; b) hazards related to the robot system, including: 1

49、) end-effector and workpiece hazards, including lack of ergonomic design, sharp edges, loss of workpiece, protrusions, working with tool changer; 2) operator motion and location with respect to positioning of parts, orientation of structures (e.g. fixtures, building supports, walls) and location of hazards on fixtures; 3) fixture design, clamp placement and operation, other related hazards;4 ISO 2016 All rights reserved ISO/TS 15066:2016(E) 4) a determination as to whether contact would be transient or quasi-static, and
