Robot Arm

About the robot arm

The Joints, Ba,se, and Tool Flange are the main components of the robot arm. The controller coordinates joint motion to move the robot arm.

Attaching an end effector (tool) to the Tool Flange at the end of the roboarm allows the robot to manipulate a workpiece. Some tools have a specific purpose beyond manipulating a part, for example, QC inspection, applying adhesives, and welding.

• Base: where the robot arm is mounted.
• Shoulder and Elbow: make larger movements.
• Wrist 1 and Wrist 2: make finer movements.
• Wrist 3: where the tool is attached to the Tool Flange.

The robot is partly completed machinery; as such, a Declaration of Incorporation is provided. A risk assessment is required for each robot application.

Light Ring

Control Box

About the Control Box

The Control Box houses the connection ports and Controller Inputs and Outputs (I/O) used in robot arm programs and installations. The connection ports are used for external connections. The I/O is a group of electrical interfaces used for communication and configuration.

For detailed descriptions of the Control Box connection ports and the Controller I/O, see the Installation.

Teach Pendant with 3-Position Enabling Device

Description

Depending on the robot generation, your Teach Pendant can include a built-in 3PE device. This is called a 3-Position Enabling Teach Pendant (3PE TP). Higher payload robots can only use the 3PE TP.

If you are using a 3PE TP, the buttons are located on the underside of the Teach Pendant, as illustrated below. You can use either button, according to your preference.

If the Teach Pendant is disconnected, you are required to connect and configure an external 3PE device. The 3PE TP functionality extends to the PolyScope interface, where there are additional functions in the Header.

NOTICE

• If you have bought a UR15, UR20 o,, or UR30 robot, a Teach Pendant without the 3PE device will not work.
• Using a UR15, UR20, or UR30 robot requires an external enabling device or a 3PE Teach Pendant when programming or teaching, within the reach of the robot application. See ISO 10218-2.
• The 3PE Teach Pendant is not included with the purchase of the OEM Control Box, so enabling device functionality is not provided.

PolyScope Overview

Descriptio PolyScope is the Graphical User Interface (GUI) on the Teach Pendant that operates the robot arm via a touch screen. You create and execute programs for the robot in PolyScope. The PolyScope interface is divided as shown in the following illustration:

• A: Header with icons/tabs that make interactive screens available to you.
• B: Footer with buttons that control your loaded program/s.
• C: Screen with fields and options to manage and monitor robot actions.

Using the Touch Screen

The touch sensitivity is designed to avoid false selections on PolyScope and to prevent unexpected motion of the robot.
The Teach Pendant touch screen is optimized for use in industrial environments. Unlike consumer electronics, the Teach Pendant touch screen sensitivity is, by design, more resistant to environmental factors such as:

• water droplets and/or machine coolant droplets
• radio wave emissions
• other conducted noise from the operating environment.

For best results, use the tip of your finger to make a selection on the screen. In this manual, this is referred to as a “tap”. A commercially available stylus may be used to make selections on the screen if desired.
