Description

Electrically-driven bionic quadruped robot
Technical Field
The present disclosure relates to a bionic quadruped robot, and more particularly, to an electrically driven bionic quadruped robot.
Background
The research of the four-footed bionic robot has been one of the hot spots of the research in the field of domestic and foreign robots for a long time. The robot can stably walk in a complex non-structural environment, can replace people to finish many dangerous operations, and has many potential application prospects in industries such as military affairs, mining, nuclear energy industry, celestial surface detection, fire control and rescue, building industry, agriculture and forestry felling, teaching and entertainment and the like. The research of the four-footed bionic robot started in the 60's of the 20 th century, and a plurality of representative robot prototypes are generated. In recent years, the design of a robot with high speed, high bearing capacity, low energy consumption and a power source becomes the research focus of a quadruped robot. At present, the famous research results at home and abroad comprise a BigDog, AlphaDog, LittleDog and Cheetah Cheetah which are researched and developed by the Boston dynamic company in America, a Hyperion 4 robot which is researched and developed by professor of Japan Qianye Faugua industry and Rice field, a hydraulically-driven four-footed bionic robot which is researched and developed by Shandong university, and the like. The leg mechanical structure of the existing quadruped robot is almost composed of serial mechanisms. The series structure is simple, control modeling is easy, and drivers are mostly arranged on legs, so that the lower-level drivers become loads of the upper-level drivers, and the requirement on driving capability is high. The parallel legged robot is mainly researched in the direction of a single-foot or double-foot walking robot at home and abroad. For example, the WL series walkers at early rice university in japan, the Para-Walker design at gargle research. The conception of the four-foot/two-foot reconfigurable walker proposed by Wanghoubo of Yanshan university is provided in China. The parallel leg structure has higher rigidity, can improve the load-weight ratio of the robot, but is limited in the working space of the mechanism, and is difficult to finish high-speed walking obstacle crossing operation.
The publication No. CN 101927793A discloses a variable structure quadruped robot structure interconverting creeping motion and vertical motion, which comprises a quadruped robot organism and four limbs fixed on the quadruped robot organism, wherein each limb is controlled by three steering engines, and the steering engines are in a series structure. Meanwhile, the machine body in the structure is a whole, so that the flexibility of movement is limited.
Publication No. CN 101811525 a discloses a "hydraulically driven four-legged robot moving mechanism with a centroid adjusting device", in which four legs are arranged under a trunk, all hydraulically driven, and each leg has redundant degrees of freedom, which increases the complexity of mechanism control. In addition, the hydraulic drive improves the volume and the weight of the whole mechanism, and the whole mechanism is inconvenient to carry, transport, disassemble and assemble.
Publication No. CN 101791994 a discloses "a walking mechanism of a cam-driven controlled quadruped robot", which is divided into a front and rear leg unit and a universal connection unit connecting the front and rear leg units. The gimbal assembly merely provides a passive form of motion that is not controlled manually, which is detrimental to the motion and balance control of the mechanism.
