Embodiment 1
[0032] Please refer to Figure 1~3 , the present embodiment discloses a multi-joint spine 1100, the multi-joint spine 1100 includes a first spine 1110, a second spine 1120 and a third spine 1130 which are sequentially articulated to form a three-section main body joint structure, thereby simulating four The spine bending motion of the legged creature can improve the speed and flexibility of the quadruped robot.
[0033] Based on the hinge relationship, the first spine 1110 and the third spine 1130 can respectively rotate around the hinge axes of themselves and the second spine 1120 to realize the bending motion of the multi-joint spine 1100 . Under the foregoing structure, the multi-joint spine 1100 has a three-section basic configuration. The three-section basic configuration has a wide bending angle, which can achieve a large body bending, so as to effectively increase the running distance. At the same time, the motion law of the spine in the three-stage basic configuratio...
Embodiment 2
[0046] see Figure 4 , this embodiment discloses a spine-type quadruped robot 1000, the spine-type quadruped robot 1000 includes the multi-joint spine 1100 and robot lower limbs 1200 introduced in Embodiment 1. As mentioned above, the lower limbs 1200 of the robot are installed on the first spine 1110 and the third spine 1130 respectively, so that the robot has four limbs (which can be divided into front and rear limbs).
[0047] Among them, the front and rear limbs of the robot can be formed by a linear array of robot lower limbs 1200 with the same orientation, forming such structural forms as ">" shaped legs. Alternatively, the front and rear limbs of the robot have a symmetrical distribution relationship. Exemplarily, in the latter form, the robot lower limb 1200 located at the first spine 1110 and the robot lower limb 1200 located at the third spine 1130 are symmetrical about the second spine 1120 . In a symmetrical form, the front and rear limbs of the robot can adopt d...
