Gear shift patterns in uncertain terrestrial locomotion systems. - In: Applied non-linear dynamical systems, (2014), S. 37-48
The paper focusses on various gear shift patterns in an uncertain terrestrial locomotion system, i.e., in a wormlike locomotion system (WLLS). A WLLS in this theory is understood as a system living in a straight line (one dominant linear dimension) with no active (i.e., driving) legs nor wheels. A mechanical model comprises a chain of discrete mass points (1) connected by viscoelastic force actuators and (2) having ground interaction via spikes which make the velocities unidirectional. A spike means any device which realizes this restriction. The distances between two consecutive mass points are changed by an adaptive controller. In combination with the ground contact spikes, this results in an undulatory locomotion of the system. Optimal gaits which achieve a defined number and succession of resting mass points as well as the resulting velocity are developed in numerical investigations. We present a gait shifting procedure incorporating a combination of speed adjustment and gait change that enables optimal crawling for predefined limits of actuator or spike force load.

This work is inspired and motivated by the sophisticated mammals sense organ of touch: vibrissa. Mammals, especially rodents, use their vibrissae, located in the snout region - mystacial vibrissae - to determine object contacts (passive mode) or to scan object surfaces (active mode). Here, we focus on the passive mode. In order to get hints for an artificial sensing prototype, we set up a mechanical model in form of a long slim beam which is one-sided clamped. We investigate in a purely analytical way a quasi-static sweep of the beam along a given profile, where we assume that the profile boundary is strictly convex. This sweeping procedure shows up in two phases, which have to be distinguished in profile contact with the tip and tangentially contact (between tip and base). The analysis eventuates in a phase decision criterion and in a formula for the contact point. These are the main results. Moreover, based on the observables of the problem, i.e. the clamping moment and the clamping forces, which are the only information the animal relies on, a reconstruction of the profile is possible - even with added uncertainty mimicking noise in experimental data.
