Yes, industrial handling robots typically have the ability to adjust the force they apply to the target object. This ability is crucial for ensuring the safety and integrity of objects during transportation, especially when handling fragile items or tasks that require meticulous handling.
The following are some methods and techniques for industrial handling robots to adjust the applied force:
Force/torque sensors: Industrial handling robots are often equipped with force/torque sensors, which can monitor the force and torque applied by the robot's end effectors (such as robotic arms or fixtures) on objects in real time. Through these sensors, robots can perceive the applied force and adjust it according to preset parameters to ensure that excessive force is not applied to objects.
Flexible fixtures: Robots can use flexible or adaptive fixtures designed to adapt to objects of different shapes and sizes, and can adjust clamping forces to protect objects from damage. Flexible fixtures can achieve force adjustment through pneumatic, hydraulic, or electric means.
Closed loop control system: The robot control system can use closed-loop control methods to dynamically adjust the applied force based on real-time feedback information. For example, when a robot grabs an object, it can gradually increase the clamping force until the force sensor detects the appropriate force. This method can ensure precise control of force and avoid applying too much or too little force to objects.
Force control algorithm: The robot control system can implement advanced force control algorithms, such as impedance control, stiffness control, etc. These algorithms allow robots to adjust their motion patterns and applied forces when in contact with objects, thereby achieving precise control of forces.
Pre set parameters and programming adjustments: During the programming phase, operators can set appropriate force parameters based on the characteristics of the object (such as weight, material, shape). These parameters can be stored in the robot's control system, and the robot will adjust the applied force based on these parameters when performing transportation tasks.
Through these methods, industrial handling robots can accurately adjust the force they apply to the target object to ensure the safety and integrity of the object during the handling process. This ability not only enhances the adaptability and flexibility of robots, but also expands their application range, enabling them to handle a wider range of materials and tasks.
