Frequently Asked Questions About Universal Robots (4-6)

4. The function of dragging and teaching of Universal Robots is very practical, how is it realized?

One of the biggest features of Universal Robots as a collaborative human-robot robot is that it can be dragged and taught.

To realize the drag teaching, you first need to complete the initialization process in the teach pendant: in the "Set Robot" window, select "Initialize Robot", click the "On" and "Start" buttons, then press the black "Free Drive" button on the back of the teach pendant with your finger, and then pull the mechanical arm with your other hand to drag and teach.

When dragging and teaching, remember not to use too much force, if you feel a lot of resistance, do not deadlift, and check where there are obstacles.

We know that after the servo of the robotic arm motor is energized, it can maintain its position and attitude because of the action of electromagnetic force, and at this time, the robotic arm cannot be pulled. When the "free drive" button is pressed, the electromagnetic force of the joint is released, at this time, the robot will add an appropriate counter-driving force to balance the gravity according to the gravity of each joint at present, and the robotic arm is in a suspended state, and it can be dragged and taught.

5. Is there any permission setting or password protection for the use of Universal Robots Teach Pendant?

There are two functions in the Universal Robots Teach Pendant that allow you to set password protection: one is to set a security password, which is mandatory to view and modify security parameters. The new robot that the user gets does not have a secure password, and a new password needs to be set on the spot; The other is the system password, which is used to view or modify the program, this password is not mandatory and can be omitted.

Both passwords are set and modified in the "Set Password" window in the "Set Robot".

If you need to set it, you can connect to the robot control box through the host computer and complete it through the SetUserRole command of the Dashboard protocol.

6. What coordinate systems does Universal Robots have? How does it work?

Universal Robots are 6-jointed robots, so they conform to the Cartesian coordinate system and work with the right-hand rule.

Universal Robots comes with two coordinate systems, one is the base coordinate system and the other is the tool coordinate system, which is also called a feature within Universal Robots. The base and tool coordinate systems cannot be deleted or changed.

The base coordinate system is based on the center of the flange of the manipulator arm base as the origin, the flange is upward to the Z-axis positive direction, the direction of the flange out of the cable is the Y-axis positive direction, and the right-hand rule is used to determine the X-axis positive direction; The tool coordinate system is based on the center of the flange (or TCP) at the tool end as the origin, the outward direction of the flange is the positive direction of the Z axis, and the reverse direction of the signal line joint at the tool end is the positive direction of the Y axis, and the positive direction of the X axis is determined by the right-hand rule.

In addition to the above two coordinate systems, Universal Robots can customize the user's coordinate system using the three-point method in the "Features" option under the "Installation Settings" window. Under the Move window, use the Features option in the upper right corner to switch the use of coordinate systems.
