ABSTRACT
Features of the cerebellar neuronal circuit in vetebrates are implemented in this bio-inspired model of movement command and control. The model was designed as a heuristic validation test of motor control by oscillatory neurons. At the core of the design are the intrinsic electrical properties of central neurons and the dynamics of the network they generate. Specifically, the basis for this model of vertebrate CNS motor control is the dynamics of the olivo-cerebellar system, which is known to support internal motor coordination timing. This model is applied to the control of the motor plant (the mechanical properties) of an underwater vehicle. The internal representation of the geometrical properties of the motor plant gives context to the incoming sensory information that organizes motor control by resetting the phase of inferior olive neuron oscillations, in a feedback mode. In the present model, the direction of the vehicle displacement is captured by a camera, and transformed into the phase shift modulation of a set of oscillatory elements that embody a dynamic internal geometry, providing the control variables for the underwater vehicle in three dimensions.
