The position - force curve of ICF400 elastomer and its constructed equivalent
In the second experiment, two materials with very similar mechanical properties (H1N
and ICF400) were simulated by the tactile display (Table 11.3). This time, the results of
the simulation showed some discrepancies in recognition.
The reason is that this test required the subject to distinguish between two materials
with similar mechanical properties, as shown in Figure 11.26, without visual feedback.
11.10 Summary and Conclusion
A system for displaying the softness of different materials, and which could potentially
be used for telerobotic surgery and virtual reality, was proposed and tested and comprised
a linear actuator, a force sensor, a data acquisition card, and processing software.
