[0033] As shown in the drawings,Figure 1 , Figure 4 , Figure 5 As shown, the kangaroo-like robot has a set of forearm mechanisms on each side. The two forearm mechanisms operate on the same principle and are symmetrical. Taking the right forearm mechanism as an example: the upper forearm 6 is a hollow structure with a horizontally arranged circular shaft 6.1 on its upper right side. The upper end of the upper forearm 6 is rotatably mounted on the right side of the main body 1.

[0034] Example 1: The power and control unit 9 integrates a lithium battery pack and a data processing system. The data processing system can process the motion parameters of the kangaroo robot in real time and control each power component. The gyroscope sensor 8 can detect the dynamic parameters of the kangaroo robot, such as pitch angle, acceleration, and spatial movement speed, in real time and feed the parameters back to the data processing system in real time.

[0035] Example 2: Standing method of a kangaroo-like robot: as follows Figure 6 As shown, the two supporting legs 5 support the ground, the tail 2 rotates downward and supports the ground, the transverse spindle 21 moves to the right so that the gear 16 extends to the left and meshes with the rack on the elastic rod 4, the clutch motor 13 drives the elastic rod 4 to move downward so that the main body 1 stands upright. At this time, the two supporting legs 5 and the tail 2 form a three-point support, realizing the stable standing of the kangaroo robot.

[0036] Example 3: Jumping method of a kangaroo-like robot: as follows Figure 7 , Figure 8As shown, first, the horizontal shaft 21 moves to the right, so that the gear 16 extends to the left and engages with the straight rack on the elastic rod 4. The clutch motor 13 drives the elastic rod 4 to move upward, so that the take-off spring 12 is compressed and stored. At this time, the main body 1 is tilted forward. In this process, the gyroscope sensor 8 can detect the tilt angle of the main body 1 in real time, and the two swing leg motors 10 control the angle of the two rear legs 3 to fine-tune the tilt angle of the main body 1 in real time. At the same time, the electric cylinder 15 controls the rotation angle of the tail 2 to make the kangaroo robot always keep balance. After the take-off spring 12 is stored, the electromagnet 20 is powered off, the horizontal shaft 21 moves to the left under the elastic force of the reset spring 19, and the gear 16 moves to the right under the action of the horizontal rod 22 and the horizontal rod 17. The gear 16 disengages with the straight rack, so that the elastic rod 4 moves downward under the elastic force of the take-off spring 12, and the two supporting feet 5 apply pressure to the ground, realizing the take-off action of the kangaroo robot.

[0037] After the kangaroo robot takes off, the gyroscope sensor 8 detects the tilt angle of the main body 1 in the air in real time, and the data processing system controls the two swing leg motors 10 to rotate according to the tilt angle of the main body 1 in the air, so that the two rear legs 3 rotate forward by an appropriate angle to prepare for the landing action of the kangaroo robot. In this process, the tilt angle of the main body 1 in the air can be adjusted by rotating the tail 2.

[0038] When the kangaroo robot lands, the two supporting feet 5 first contact the ground, and then the main body 1 continues to move downward and compresses the take-off spring 12. When the gyroscope sensor 8 detects that the downward movement speed of the main body 1 is zero, it means that the take-off spring 12 has been stored. At this time, the electromagnet 20 is powered off, the horizontal shaft 21 moves to the left under the elastic force of the reset spring 19, so that the gear 16 moves to the right and disengages with the straight rack. In this process, the tail 2 can rotate in real time, so that the main body 1 always maintains a balanced posture. Continuous take-off and landing actions can realize the continuous jumping of the kangaroo robot.

[0039] Example four: turning method of kangaroo robot: as shown, Figure 9 First, the gears 16 of the two clutch motors 13 engage with the straight racks on the corresponding elastic rods 4. The two swing leg motors 10 rotate to make the main body 1 tilt forward. At the same time, the center of gravity of the kangaroo robot is adjusted by rotating the tail 2. The two front arms 6 are driven by the two large arm motors 14 to swing forward, and the front small arm 7 is driven by the small arm motor 23 to swing downward, so that the two rollers 7.1 contact the ground and provide support for the kangaroo robot.

[0040] When turning left, first the right clutch motor 13 drives the right elastic rod 4 to move down, so that the front end of the right supporting leg 5 supports the ground, then the right leg swinging motor 10 drives the back leg 3 to swing back to a certain angle, then the clutch motor 13 drives the elastic rod 4 to move up, then the leg swinging motor 10 drives the back leg 3 to swing forward to the initial position, and the above actions are repeated several times, so that the kangaroo robot turns left;

[0041] When turning right, first the left clutch motor drives the left elastic rod to move down, so that the front end of the left supporting leg supports the ground, then the left leg swinging motor drives the left back leg to swing back to a certain angle, then the left clutch motor drives the left elastic rod to move up, then the left leg swinging motor drives the left back leg to swing forward to the initial position, and the above actions are repeated several times, so that the kangaroo robot turns right.
