Abstract
This paper provides experimental evidence in support of the hypothesis that the Switching Four-bar Mechanism (SFM) model may serve as a template for miniature legged systems in quasi-static operation. The evidence suggests that the SFM captures salient motion behaviors of morphologically distinct centimeter-scale legged robots. Captured behaviors are then used for planning and control at small scales, thus demonstrating the practical utility of the SFM in navigation tasks.

Notes
- 1.
Due to symmetry, the above description holds for the left pair by replacing indices \(\text {1}\) and \(\text {2}\) with indices 3 and 4, respectively.
- 2.
In fact, a duration of 3 s turns out to be a good trade-off between path dispersion, and length which affects the overall computationally complexity; see [12].
- 3.
The number of steps has been chosen empirically to provide adequate resolution for the touchdown and liftoff configurations in 3 sec-long experimental data.
