This part of GB 11291 specifies requirements and guidelines for the inherent safe design, protective measures and information for use of industrial robots, as defined in Clause 3. It describes basic hazards associated with robots and provides requirements to eliminate, or adequately reduce the risks associated with these hazards. Noise as a potential hazard is not dealt with in this part, but will be fully covered in Part 2 of GB 11291.
This part of GB 11291 does not apply to non-industrial robots although the safety principles established in "Robots for Industrial Environment-Safety Requirements" may be utilized for these other robots. Examples of non-industrial robot applications include, but are not limited to: undersea, military and space robots, tele-operated manipulators, prosthetics and other aids for the physically impaired, micro-robots (displacement<1mm), surgery or healthcare, and service or consumer products.
Notes: 1 Requirements for robot systems, integration, and installation are covered in Part 2.
2 Additional hazards may be created by specific applications (e.g. welding, laser cutting, machining). These hazards may need to be considered during robot design.

3.5 Collaborative workspace
Workspace within the safeguarded space of the robot work cell, where the robot and a human can perform tasks simultaneously during production operation.
3.6 Coordinated motion

3.15 Pendant, teach pendant
Hand-held unit linked to the control system with which a robot can be programmed or moved.
[GB/T 12643-1997, definition 6.8]
3.16 Programme
3.16.1 Control programme
Inherent set of instructions which defines the capabilities, actions, and responses of a robot system.
Note: this programme is fixed and usually not modified by the user.
[GB/T 12643-1997, definition 6.1.2]
3.16.2 Task programme
Set of instructions for motion and auxiliary functions that define the specific intended task of the robot system.
Notes: 1 This type of programme is normally generated by the user.
2 An application is a general area of work, a task is specific within the application.
[GB/T 12643-1997, definition 6.1.1]
3.16.3 Task programming
Act of providing the task programme.
[GB/T 12643-1997, definition 6.2.1]
