With the continuous development of intelligent manufacturing and automation technology, industrial robots are widely used in automobile manufacturing, electronic assembly, medical equipment and other fields. However, traditional industrial robots mainly rely on position control to complete tasks, and lack the ability to perceive and control environmental interaction, so it is difficult to cope with work scenes that require precise force control, such as precision assembly, grinding and polishing, and flexible grasping. Therefore, force control technology has become an important research direction to improve the intelligent level of industrial robots.<\/p>\n

First, the basic concept of force control<\/p>\n

The so-called Force Control means that when the robot is in contact with the environment, it can sense and control the magnitude and direction of the force exerted on the environment, so as to achieve stable, safe and efficient operation. Different from traditional position control, force control pays more attention to the interaction between robot and external objects, thus achieving more flexible operation.<\/p>\n

\u3000\u3000Second, the technical realization offorce control<\/p>\n

There are usually the following ways for industrial robots to realize force control:<\/p>\n

\u3000\u30001. Method based onforce sensor<\/p>\n

Installing a six-axis force\/torque sensor at the end of the robot is the most direct way to realize force control. The sensor can detect the force and torque in X, Y and Z directions in real time, and adjust the trajectory of the robot through the feedback control algorithm, thus maintaining a constant contact force. This method has high precision and is suitable for force-sensitive tasks such as grinding and assembly.<\/p>\n

2. Indirect force control based on current feedback. <\/p>\n

The motor current of each joint of the robot is directly proportional to its output torque. By detecting the change of motor current, the external force on each joint of the robot can be estimated, and then force control can be realized. This method does not need additional sensors, and its cost is low, but its anti-interference ability is poor and its accuracy is limited.<\/p>\n

3. Model-based adaptive control method <\/p>\n

Using the robot dynamics model and the external environment model, the dynamic response to the external force is realized by calculating and adjusting the control strategy in real time. This method is suitable for complex and changeable working environment, and has strong adaptability and robustness.<\/p>\n

4. Hybrid control strategy: position\/force hybrid control. <\/p>\n

In many practical applications, simple position control or simple force control can not meet the demand. Therefore, the position\/force hybrid control strategy is often adopted, that is, the position control is maintained in some directions and the force control is carried out in other directions to achieve the best working effect. For example, in the process of surface grinding, the robot adopts position control along the direction of surface movement, while force control is adopted in the vertical direction to maintain constant pressure.<\/p>\n

Third, application scenarios and challenges<\/p>\n

Force control technology has been widely used in many industrial fields:<\/p>\n

-Parts assembly: The robot is required to control the appropriate contact force during the operations such as insertion and buckling to avoid parts damage.<\/p>\n

-Surface treatment: such as grinding, deburring, polishing, etc., it is necessary to maintain a constant pressure to improve the processing quality.<\/p>\n

-Flexible grasping: When grasping fragile or irregular objects, the clamping force should be adjusted through force feedback to avoid being pinched or slipping.<\/p>\n

Although the force control technology has made great progress, it still faces many challenges, such as the balance between sensor accuracy and cost, the difficulty of modeling in complex environment and the high real-time requirement.<\/p>\n

\u3000\u3000Fourth, the future developmentdirection<\/p>\n

\u3000\u3000With the development of artificial intelligence, sensing technology and new materials, the future industrial robots will develop in the direction of higher precision, greater flexibility and higher intelligence. The combination of deep learning and force control algorithm, the integration of new flexible sensors and the application of cloud collaborative control technology will further promote the in-depth application of control technology in frontier fields such as man-machine collaboration and intelligent manufacturing.<\/p>\n

In a word, force control technology not only expands the application boundary of industrial robots, but also significantly improves their flexibility and intelligence level, and is one of the key technologies to realize high-end manufacturing and intelligent manufacturing.<\/p>\n","protected":false},"excerpt":{"rendered":"
