Addressing 9 Common Questions and Concerns Regarding Force Sensing Technology

Integrating force sensing technology into robotic applications can be a decision that raises numerous uncertainties. It is crucial to thoroughly consider all aspects of the task at hand before making a final determination. In this blog post, we aim to address nine common doubts that often arise when contemplating the implementation of force sensing in robot design:

‍

Will force sensing be compatible with my specific application?

‍

It is natural to question whether force sensing is applicable to your particular task. While force sensors have a broad range of potential uses, it is essential to assess whether incorporating force sensing will truly provide measurable benefits. Consider if your application requires consistent force application, collision detection, or item weighing.

‍

Will the robot be limited to slow movements?

‍

Concerns may arise regarding the speed at which a robot can operate when utilizing force sensing. While it is true that some force sensors exhibit sensitivity to rapid movements, it is not a requirement for the robot to move slowly for force sensing to function effectively. Numerous applications exist where high accuracy is not necessary, allowing for faster robot movements.

‍

Can force sensing be employed for object detection?

‍

Object detection is often associated with vision sensors; however, force sensing can also serve as a reliable alternative. In certain scenarios, force sensors can outperform other sensing options, particularly when detecting the presence of an object, even in challenging lighting conditions or when objects are partially obstructed.

‍

Is deploying force sensing a complex process?

‍

Historically, integrating force sensing into robots involved intricate programming and a deep understanding of force control algorithms. Thankfully, with the advent of user-friendly force sensing technologies and intuitive programming options, the deployment process has become significantly simpler.

‍

Will force control implementation be necessary?

‍

Force control, a control algorithm enabling robots to utilize force sensor signals to influence their movements, is often associated with force sensing discussions. However, modern robots and software solutions like Force Copilot allow for the utilization of force sensing without requiring in-depth knowledge of force control principles.

‍

Will force sensing function reliably in my environment?

‍

The working environment's compatibility with force sensing is a valid concern, considering the sensitivity of certain force sensors. Factors such as dust or high humidity may impact performance. However, it is typically feasible to find a force sensor suitable for specific environmental conditions.

‍

Will noisy environments interfere with force sensing?

‍

In environments with substantial electrical noise, the potential interference with force sensors becomes a valid worry, especially for sensors utilizing strain-gauge technology. Fortunately, some sensing technologies are designed to mitigate the impact of noise.

‍

Can force sensors handle vibrations?

‍

Another common doubt is whether force sensors can effectively withstand vibrations. Excessive vibrations can indeed affect the accuracy of force sensor signals, but the level of vibration resistance varies among sensors. Force sensors generally have specified ratings beyond which vibrations may compromise their performance.

‍

Is force sensing too costly for my budget?

‍

Cost considerations play a vital role in deciding to adopt any new sensing technology. While some robots may already incorporate built-in force sensing capabilities, others might necessitate the acquisition of separate force sensors. Evaluating the return on investment is crucial, as demonstrating the measurable impact of force sensing on robot operations can justify the cost.

‍

By addressing these common doubts, we hope to provide a clearer understanding of the potential benefits and considerations surrounding the integration of force sensing technology in robotic applications.
