Problems solved by technology

When the traditional telescopic four-bar linkage mechanism is hydraulically driven with the same power, the joints of the legged robot highlight the unbalanced shortcomings of output torque and rotational speed, which makes it more difficult to control the joint motion, which is not conducive to the realization of the legged robot's movement, and also hinders the hydraulic pressure. Design Thoughts of Driven Legged Robot Joints

Abstract

The invention relates to a hydraulically-driven four-foot robot which belongs to the field of robots. The robot comprises a machine body (1) and four legs arranged on the machine body, wherein each leg consists of a first hydraulic cylinder body (2), a first hydraulic cylinder telescopic rod (3), a first parallelogrammic I connecting rod (4), a first parallelogrammic II connecting rod (5), a pelvic part (6), a second hydraulic cylinder body (7), a second hydraulic cylinder telescopic rod (8), a second parallelogrammic I connecting rod (9), a second parallelogrammic II connecting rod (10), thighs (11), a third hydraulic cylinder body (12), a third hydraulic cylinder telescopic rod (13), a third parallelogrammic I connecting rod (14), a third parallelogrammic II connecting rod (15), a crus (16), a spring (17), telescopic feet (18) and a soles (19). A telescopic four-connecting-rod joint transmission mechanism based on a parallelogram is adopted by the joint design of the hydraulically-driven four-foot robot, the joint control is simplified, and the moving performance of the foot type robot joints is improved.

Description

technical field [0001] The invention belongs to the application field of robot technology, and in particular relates to a hydraulically driven quadruped robot. Background technique [0002] The legged robot adapted to the mountain environment is one of the most cutting-edge topics in the field of robot research today. It integrates many disciplines such as machinery, electronics, computers, materials, sensors, control technology and artificial intelligence, reflecting the intelligence of a country. It is also an important symbol of a country's high-tech strength, and various developed countries have invested heavily in research in this field. [0003] The footed robot can climb slopes on complex ground, and can adjust the combination of front and rear high and low body movements to meet the movement requirements of mountainous environments with larger slopes, enhance the adaptability of mountainous environment movements, and improve the mobility of footed robots. Different ...
