When opting to incorporate force sensing into your robot application, whether for tactile feedback, enhanced flexibility, or maintaining a constant force on the workpiece, careful consideration must be given to ensure a smooth design phase. The market offers a range of force sensing options, each with its own advantages and suitability for robotic applications. However, selecting the right force sensing solution can be challenging, as different suppliers advertise varying features and complexities associated with force sensing in robotics.

Simplified Force Sensing Design: Streamlining the Process
To streamline the design phase and avoid unnecessary difficulties, it is essential to prioritize certain features when evaluating force sensing options. Here are some key considerations:
Compatibility: Look for force sensing technologies specifically designed for robotic applications. These sensors should seamlessly integrate with your robot's control system, allowing for straightforward communication and data exchange.
Robustness: Choose force sensors that are durable and capable of withstanding the rigors of industrial environments. They should be resistant to mechanical shocks, vibrations, and temperature variations, ensuring reliable and accurate measurements throughout the robot's operation.
Accuracy and Resolution: Prioritize force sensing solutions with high accuracy and resolution to capture precise force data. This ensures that the robot can perform tasks with the required precision, especially in applications that demand delicate force control.
Ease of Integration: Opt for force sensors that offer simple integration into your existing robot cell design. Look for standardized interfaces and compatibility with common robot models and control systems, reducing the complexity and time required for integration.
Calibration and Maintenance: Consider force sensing options that provide easy calibration procedures and minimal maintenance requirements. Sensors that offer self-calibration capabilities or automated calibration routines can significantly simplify the setup and ongoing maintenance of your robot cell.
Support and Documentation: Ensure that the force sensing solution you choose comes with comprehensive documentation, user guides, and technical support from the supplier. This will assist in troubleshooting and addressing any challenges that may arise during the design and implementation phases.
By prioritizing these features, you can simplify the design phase of your robot cell and ensure a smoother integration of force sensing capabilities. Collaborating with knowledgeable suppliers and seeking expert advice can also greatly assist in selecting the most suitable force sensing solution for your specific application, reducing complexity and enhancing the overall success of your robotic project.
Simplifying Force Sensing Design: Streamlining Complexity in Modern Robotics
To begin, it is crucial to determine the specific capabilities you require from your selected force sensing option. Analyze your robot application and identify the areas that would benefit from the addition of force sensing. Ask yourself the following questions to gain clarity:
- What is the primary task that the robot will be performing?
- Which particular steps within the task would benefit from force sensing?
- What type of force sensing is needed for each step? For example, force feedback for precise insertion, weight measurement, or consistent force application along a designated path.
- How precise does the force sensing need to be in order to accomplish the task effectively?
- Are there any other aspects of the task that could benefit from force sensing, even if they do not necessarily require it?
While you may not have a complete understanding of every aspect of the task at this point, it is beneficial to have a reasonably comprehensive understanding of how force sensing will impact your chosen task.
Fundamental force sensing needs
The three fundamental force sensing needs can generally be categorized as follows when seeking the optimal solution:
Ease of Use: Integrated Force Sensor
If your goal is to minimize integration time and effort, the most suitable option would likely be a collaborative robot equipped with an integrated force-torque sensor. While these were not widely available in the past, they are now both accessible and reliable.
Flexibility: 6-Axis Force-Torque Sensor
Many robots do not come with built-in force sensors. In such cases, the most common and versatile solution is to employ an external force-torque sensor. This option provides greater flexibility as you can mount the sensor in the most advantageous position for your specific task. Depending on the circumstances, it may be more practical to attach the sensor externally rather than at the robot's end. Incorporating a force-torque sensor does not have to be intricate, as certain sensors are designed to be user-friendly for various robot applications.
Customization: Tailored Force Sensing Solutions
In certain instances, the predefined options of integrated or external force sensors may not fully meet your requirements. In such cases, customized force sensing solutions can be developed to address your specific needs. These solutions involve designing and implementing specialized force sensing mechanisms, which may involve working closely with experts or manufacturers to tailor the sensor to your unique application.
By understanding these three basic force sensing needs, you can identify the most suitable approach for your particular application.
Integrating Force Sensing into Your Design: A Step-by-Step Approach
Once you have determined the type of force sensor required, incorporating it into your design can be approached with greater clarity. The steps to integrate force sensing will depend on the specific type of sensor chosen.
For integrated force sensors or external sensors with easy integration options, the additional components needed for your robot cell design are minimal. During integration, it is important to include the necessary programming options, but the complexities typically associated with force sensing are now handled by the robot's software. This streamlined approach simplifies the integration process.
In the case of less intuitive force-torque sensors and other sensing technologies, the design work may vary. You will need to plan for the cabling and connections leading to the force sensor. Additionally, designing interfaces in the programming stage will be necessary to ensure the sensor operates according to your intended functionality.
By considering the specific requirements of your chosen force sensor, you can effectively incorporate it into your design. Whether it involves minimal adjustments for integrated sensors or more intricate considerations for other sensing technologies, careful planning and programming will facilitate the successful integration of force sensing into your overall system.
Where to Find the Right Sensor: Discovering Suitable Force Sensing Options
Determining the ideal force sensing option for your specific situation requires a consideration of your application's requirements. It is advisable to search for a force sensor that aligns with your identified needs while offering intuitive functionality.
If your robot does not come equipped with an integrated force sensor, an excellent option to explore is the Nebula Robotics force-torque sensor.
