The sensorimotor loop of simple robots simulated within the LPZRobots environment is investigated from the point of view of dynamical systems theory and several branches of motion types exist for the same parameters, in terms of the relative frequencies of the barrel and of the actuator.

Collaborative Robot Precision Task in Medical Microbiology Laboratory. This work has redefined optimality in terms of feedback control laws, and focused on the mechanisms that generate behavior online, allowing researchers to fit previously unrelated concepts and observations into what may become a unified theoretical framework for interpreting motor function. Abstracting from the sensorimotor loop, one may regard, from the point of view of dynamical system theory ( Beer, 2000 ), motions as organized sequences of movement primitives in terms of attractor dynamics ( Schaal et al., 2000 ), which the agent needs first to acquire by learning attractor landscapes ( Ijspeert et al., 2002, 2013 ). The essence of our approach is to start with a simple dynamical system, such as a set of linear differential equations, and transform those into a weakly nonlinear system with prescribed attractor dynamics by means of a learnable autonomous forcing term.
