Abstract

The present invention discloses a legged robot state sensing system based on a dual core processing technology, wherein a dual core system structure is adopted, and a SOPC technology is adopted to embed two RISC embedded processor NIOS II soft cores in a chip based on a FPGA core unit to achieve the structure. One soft core is used to establish a data acquisition kernel having a data acquisition function, and the other soft core is used to establish a data processing kernel having a data processing and communication function. Data interaction of the two kernels is achieved through a mailbox kernel Mailbox and a shared RAM memory. With the NIOS II B soft core, complete information acquisition can be achieved, while the NIOS IIA soft core performs a data fusion treatment based on the data acquired by the NIOS II B soft core. According to the present invention, a state sensing technology facing the complex legged robot is adopted, and characteristics of information completeness detection, high speed data parallel processing, real-time data communication, high reliability, and the like are provided.

Description

technical field [0001] The invention relates to a state perception system of a legged robot based on dual-core processing technology. Background technique [0002] With the development of the economy and the improvement of automation requirements in all walks of life, various robots have entered the field of human life and production to replace or imitate humans to perform various complex tasks. Among them, the footed robot has the characteristics of simple structure, flexible movement, strong carrying capacity, good stability and strong environmental adaptability. Therefore, the footed robot is especially suitable for the field of military border defense, and is used to accompany border guards to patrol and transport materials. Among the various technologies for controlling the activities of legged robots, one of the most critical technologies is the state perception technology of legged robots. [0003] At present, the state perception of footed robots at home and abroad ...
