Universal Robots – How many control methods are there for industrial robots?

Create Date: 2024-8-30 12:03:23|Source: Universal Robots/UR

1. Point-to-point control (PTP) controls the position and attitude of the industrial robot end-effector at certain specified discrete points in the workspace. Ability to move from one point to another. These locations will be recorded in the control storage device. PTP robots do not control the path from one point to the next. Common applications include component insertion, spot welding, drilling, machine loading and unloading, and rough assembly operations.

2. Continuous trajectory control (CP): The control mode realizes the continuous control of the terminal actuator of the industrial robot in the working space. The industrial robot adopts CP control on the control path, and the robot can stop at any specific point. The control memory of the gripper must clearly store all the points. Some continuous path control industrial robots can also follow a programmed smooth curved path. The programmer manually moves the industrial robot arm through the required path, and the control unit stores a large number of single-point locations along the memory path.

3. Torque control mode: when assembling and placing the workpiece, in addition to accurate positioning, it is also required to use appropriate force. This control method is basically the same as the principle of position servo control, but the feedback is not positional. Therefore, torque sensors must be used in the system. Adaptive control is sometimes achieved using sensor functions such as proximity and slip.

Universal Robots – a common fault with welding robots Universal Robots – a common fault with welding robots

1. Welding deviation problem: it may be that the welding position is incorrect or there is a problem when looking for the welding gun. In this case, it is necessary to consider whether the TCP (welding torch center point position) is accurate and adjust it. If this situation occurs frequently, it is necessary to check the zero position of each axis of the robot, and re-calibrate it to repair.
