A mobile robot comprising a body and at least six compliant legs each having only one actuator. The compliant legs are mounted to the body for movement relative thereto in a single degree of freedom. A controller is operably coupled to the actuator of each compliant leg, the controller selectively actuates the actuators to drive the compliant legs in an alternating tripod gait.

A method of machine control including the recreation of a tone reproduction curve by providing a look up table. The look up table incorporates a covariance matrix of elements containing n tone reproduction samples. A matrix multiplier responds to sensed developed patch samples and to the look up table to reproduce a complete tone reproduction curve. A control reacts to the reproduced tone reproduction curve to adjust machine quality.

Optimal reconstruction of tone reproduction curve

Fundamental machine functions such as the Tone Reproduction Curve need to be divided into regions of smaller units so that each unit can be interrelated to some aspects of the internal machine process. A first step toward that is by decomposing measured TRC in terms of what are known as 'orthogonal basis functions'. Two significant applications for orthogonal basis functions may be extensive use in color controls to maintain color consistency for every page, every time and all the time. The use of basis functions might also lead to a new soft sensor for use in certain machines.
