Title:
LEG-TYPE MOVING ROBOT AND FLOOR REACTION FORCE DETECTION DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2003/057421
Kind Code:
A1
Abstract:
A displacement sensor (70) for producing an output showing the displacement of the ground-contact end of a foot unit (22) with respect to a second joint (18, 20) is provided inside or in the vicinity of an elastic element (382), and a floor reaction force acting on a foot unit based on an output from the displacement sensor is calculated by using a model that describes the relation between displacement and stress produced at an elastic element according to the displacement of the sensor, whereby it is possible to calculate a floor reaction force accurately and let a leg-type moving robot (1) walk further more constantly. In addition, dissimilar detection means are combined to form a dual system of sensors for an improved reliability in detection. A reliability in detection is further improved by a displacement sensor or the like that self-diagnoses whether or not it is deteriorated or abnormal and by temperature compensation without the provision of a temperature sensor.
