A Method of Determining the Separation Plane of a Knob-Shaped Measuring Handle for the Measurement of Hand-Arm-Impedances

Use of data-driven design for the development of knob-shaped handles in the context of impedance measurements

“…In the current state of research, there is no proper design for a knobshaped measuring handle. A main concern is the angular position of the separation plane that divides the measuring handle to place the force sensors for gripping measurement in between (Schroder et al, 2020). In (Schroder et al, 2020), a method for determining the angular position of this separation plane of a knob-shaped measuring handle is discussed.…”

For this purpose, Schroder et al (2020) use an optimization algorithm that extracts the angular position of the separation plane from experimental data. The algorithm transforms the 3D model of the orbital sander handle into a 2D projection.…”

“…The optimized angular position of the separation plane is then transformed back into the 3D model of the orbital sander handle. However, this transformation in (Schroder et al, 2020) only considers the back view of the handle, which is defined as the x-y plane. Consequently only the projection of the separation plane's edge in the x-y plane is calculated.…”
