Title: Preprocessing method for fuzzy inference
Inventor: USHIDA HIROHIDE
IPC: G06F9/44
Filed: 1991-11-22
Abstract: PURPOSE:To reduce memory capacity to be required and to attain fuzzy inference with a high processing speed by separating a category based upon a decision function obtained from category distribution formed from sample data. CONSTITUTION:Decision analysis is applied to plural category distributions formed from sample data X to find out a decision function C1 and a membership function K is formed from the frequency distribution of the sample data X. Preferably plural obtained decision functions C1 are mutually compared, a required function out of similar decision functions is deleted and the membership function K is formed from the frequency distribution of sample data X corresponding to the remaining functions. A fuzzy rule K' indicating which category distribution includes the function K may be formed based upon the function K. Since each category is divided by a few dividing faces (decision functions), the number of membership functions and the number of fuzzy rules formed based upon the divided categories can be reduced.

Title: Leg-type moving robot and operation control method for the same
Inventor: HATTORI YUICHI
IPC: B25J13/00
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a leg-type moving robot capable of autonomously and smoothly standing up from its various overturning postures such as falling on its face, falling on its back, falling on its side or the like. SOLUTION: This leg-type moving robot has a degree of freedom on each roll, pitch and yaw shaft of a body part. The robot can smoothly stand up from an arbitrary overturning posture by using the degree of freedom of the body parts. The concentration of the load to a specific part can be prevented by reducing the load and the required torque to each movable part excluding the body part, and dispersing and averaging the load among the movable parts. As a result, the reliability in the operation of the robot can be improved, and the energy efficiency in a period of the standing-up operation can be improved.

At this time, the difference is set to the threshold voltage, so the error voltage due to an analog switch which biases the input and output of the inverting amplifier exert a large influence on the offset voltage of a comparator.
