Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] Such as figure 1 and 2 As shown, the bionic jumping robot includes a frame, a front leg jumping mechanism, a rear leg jumping mechanism and a transmission mechanism. The front leg jumping mechanism comprises a front leg shaft 1, a front leg power rod 2, a small front leg spring 3, a front leg connecting rod 4, a large front leg spring 5 and a front leg sole bar 6. The front leg shaft 1 is supported on the frame. The two ends of the front leg shaft 1 are respectively fixed to the inner ends of the two front leg power rods 2; the middle parts of the two front leg power rods 2 are respectively hinged to one end of the two front leg connecting rods 4. The other ends of the two front leg connecting rods 4 are respectively hinged with the middle parts of the two front leg sole bars 6 . One end of the small spring 3 of the front leg and the big spring 5 of the front leg...

Abstract

The invention discloses a bionic hopping robot. The number of power source pieces of an existing hopping robot is large, the effective power density is low, the weight is large, and the hopping height and the distance are small. The bionic hopping robot comprises a rack, a front-leg hopping mechanism, a rear-leg hopping mechanism and a transmission mechanism. The front-leg hopping mechanism comprises a front-leg shaft, a front-leg power rod, a front-leg small spring, a front-leg connecting rod, a front-leg large spring and a front-leg sole rod. The rear-leg hopping mechanism comprises a rear-leg shaft, a rear-leg power rod, a rear-leg small spring, a rear-leg connecting rod, a rear-leg large spring and a rear-leg sole rod. The transmission mechanism comprises a motor, a pull roll wheel, a spring, a gear set, a second driven shaft, a first driven shaft, a power rod set and a steel cable. The gear set comprises three tooth-missing gears and three full-tooth gears. According to the bionic hopping robot, through collaborative operation of the front-leg hopping mechanism and the rear-leg hopping mechanism, stable and continuous hopping advance can be conducted.

Description

technical field [0001] The invention belongs to the field of bionic robots, in particular to a bionic jumping robot. Background technique [0002] Human beings currently have in-depth research mainly on the movement of animals, but there are still many issues in the field of bionics that are worthy of research by scientists. [0003] As early as 1980, Professor Raibert of the Massachusetts Institute of Technology had developed the world's first robot capable of jumping on one leg. Later, Professor Raibert studied the two-dimensional jumping leg model similar to kangaroo jumping. Raibert has developed a kind of three-dimensional jumping mechanism again. [0004] Case Western Reserve University in the United States also conducted research on bionic robots, and then in 1992 invented a mechanical cricket powered by artificial tendons. The thighs of this robot are made of artificial tendons, which are made of a kind of polymer fiber. When using them, you only need to inflate th...
