Abstract: Various apparatus and methods include autonomous robot operations to perturb a current Bayesian equation and determining whether the perturbed Bayesian equation yields an improved probability of success of achieving a goal relative to the current Bayesian equation. In an illustrative example, the perturbation may modulate a coefficient of a parameter in the Bayesian equation. In some examples, the perturbation may include assessment of whether adding or removing a parameter may improve the probability of success of achieving the goal. The parameters of the Bayesian equation may include, for example, current state information, alone or in combination with sensor input values and/or historical information, for example. In some implementations, the robot may advantageously autonomously optimize its operations by perturbing a current Bayesian equation associated with, for example, a current goal, sub-goal, task, or probability of success criteria.

Abstract: Apparatus and associated methods relate to an endless-track drive wheel having axially-projecting roller cogs circumferentially distributed, the cogs configured to engage a lugged inner surface of an endless track at a radial distance from a wheel axis greater than a wheel radius. In an illustrative embodiment, an exemplary drive wheel may have cogs axially projecting from two opposing faces of the drive wheel. In some embodiments, each cog may include a roller bearing or bushing annularly coupled to a center post. In some embodiments, the cogs on each face may be periodically distributed at a radial distance from the axis of the drive wheel. The endless track may have a series of track lugs projecting from an interior surface. In some embodiments, the track lugs may be periodically arranged along the track to have a pitch corresponding to the pitch of the drive-wheel cogs. In some embodiments, the roller bearings may advantageously provide low-resistance drive coupling to the track.
