Safety

2 Safety

The safety section describes general safety guidelines to be fol­lowed with this product, explanation of the notification found in this manual, and safety precaution that apply to the product. More specific notification are imbedded within the sections of the manual where they apply.
2.1 General Safety Guidelines
The customer should verify that the transducer selected is rated for maximum loads and torques expected during operation. Be­cause static forces are less than the dynamic forces from the accel­eration or declaration of the robot, be aware of the dynamic loads caused by the robot.
2.2 Safety Precautions
NOTICE
Material damage due to wrong up setting.
When initially setting up the Demo Programs, position the robot manually in order to avoid damaging parts, especially the sensor cable.

Overview

3 Overview

This manual explains how to install and operate the SCHUNK Uni­versal Robot(UR)Cap software and demo programs so that the UR robot can be used with an SCHUNK Force/Torque (F/T) Ethernet sensor rather than the UR robot’s calculated F/T readings. The SCHUNK URCap software is compatible with Ethernet protocol only.
F/T sensors convert sensed loads from forces and torques into electrical signals. The F/T sensor provides data to the robot. This data is the six degrees of freedom (DoF): Fx, Fy, Fz, Tx, Ty, and Tz. UR robots have algorithms to use force feedback to control the ro­bot motion. The SCHUNK URCap software provides a way to input data from an SCHUNK sensor into those algorithms by using plugin technology.
For more information on UR robots and the UR user interface, PolyScope, refer to https://www.universal-robots.com/support/. For more information on the SCHUNK F/T Ethernet sensors refer to the Ethernet AXIA manual for the FT-AXIA80 sensor and Net FT for all other SCHUNK Ethernet sensors.

URCap Software

4 URCap Software

URCap software is required to bypass the UR robot’s calculated F/T readings and program the robot to use a F/T sensor. URCap soft­ware is compatible with the FT-AXIA80 Ethernet sensor and other F/T Ethernet sensors. Contact SCHUNK for help in selecting the proper sensor for your application. Refer to Demo Programs [}34], for information about the simple and standard demo pro­grams available through the URCap software. The demo programs are included in the URCap software package that is downloaded from the website

4.3 Determining the Tooling Mass and Offset
NOTICE
Do not enter the following default values into the robot control­ler without accounting for the tooling mass by using the follow­ing equations.
Failure to account for the tooling mass and offset reduces the performance of the UR robot.
Properly account for the customer tooling, when setting up
the tool center point or TCP.
The SCHUNK-provided sensor and interface plate in the UR Kit have the following mass characteristics with no customer tooling installed:
• Mass = 0.558 kg
• Offset to the Center of Gravity in the Z direction = 22.8 mm
• Offset to the Center of Gravity in the X, Y directions = 0 mm
• Total Stack Height or Offset from the robot reference plane to the sensor reference plane = 46.4 mm
When the customer tooling is mounted to the sensor, these de­fault values change to account for both the mass of the tool and the mass of the sensor. Use the following equations to determine the values to enter in the fields of the “Setup for the Tool Center Point” screen; Refer to Figure "Setup for the Tool Center Point". The following diagram can be used as a reference for the equa­tions.

This should include the mass and location of all customer­provided fasteners and not SCHUNK-provided parts.
The location of a center of gravity can be found in most CAD packages used to design robot tooling.
Customer’s Tooling Mass The mass of the customer’s tooling that includes all fasteners
not provided by SCHUNK, in kilograms.
F/T Mass The mass of the F/T sensor including the interface plate and all
hardware required to connect the F/T sensor to the robot. The F/T mass does not include any hardware the customer uses
to mount their tooling to the F/T sensor.

5.3.1 Program Node Commands
There are three Program Node Commands that the user can select by clicking on the radio button on the “F/T Sensor Command” screen.
26
01.00 | SCHUNK Software Module for URCap | Software Manual | en | 1369443
5.3.1.1 Enable Command
The Enable command completes the following operations:
• streaming F/T data over the RDT interface on the sensor.
• forwarding the F/T data to the UR robot over the UR RTDE inter­face.
• using the F/T data in the UR program force feedback controls.
5.3.1.2 Disable Command
The Disable command completes the following operations:
• stops using F/T data from an F/T sensor.
• starts using the internal force sensing of the UR robot.
5.3.1.3 Bias Command
Biasing is useful for eliminating the effects of gravity (tool weight) or other acting forces from the force/torque data that is provided by the F/T sensor.
The bias command completes the following operations:
Operation of the URCap Software
• data collection for the forces and torques, which are currently acting on the sensor.
• use collected data as a reference for future data.
• future data has this reference subtracted, before the values are transmitted.
NOTE
When biasing, ensure the force and torque readings are steadys­tate. Biasing while the sensor is vibrating, accelerating, or deceler­ating can provide a poor reference for the user’s application.

the F/T sensor.
CAUTIONSteps 4 to 6, can use either the UR built-in F/T sensor data or the SCHUNK URCap data. The Demo Program uses the
SCHUNK URCap data through the Enable command. The Demo Program does not use the Disable command. Refer to section
Program Node Commands [}26] for more information on the
Enable, Disable, and Bias commands.
Operation
Ø The tool is moved straight down, until the sensor measures a
force greater than 2 N or the tool touches the surface.
Ø The tool is pressed against the surface with 10 N of force and
moved from the left side of the surface to the right. The robot adjusts the tool up and down to maintain 10 N of force as it travels across the surface.
Ø When the tool reaches the right side of the surface, it stops and
then moves up to its checkpoint position.
Ø The process repeats in reverse. The tool moves down until it
touches the surface, travels from the right side of the surface to the left at 10 N, and lifting up.
Ø This program loops until stopped.
NOTE
SCHUNK F/T Sensors provide status conditions to the robot. Refer to Acceptable Status Conditions [}32] for Acceptable Status Con­ditions that the user can set the URCap software to ignore so that the UR robot continuously operates.

Operation
7.2 Simple Demo
The Simple Demo consists of the following steps:
Ø The Simple Demo Program moves the end of the robot arm
straight up and down.
Ø If the sensor detects the force of the robot arm moving down
onto an object, the robot arm stops and moves upwards again.
NOTICE!The Simple Demo Program stops when the sensor de­tects a force greater than 2 N.
Ø This motion repeats until the program is stopped.
