The working principle of the invention is as follows:
when the machine is changed from conventional running to rolling running, the front and rear feet are divided into a front foot part and a rear foot part, the first worm 5-4 of the lower front foot 22 (lower rear foot 3-2) is driven by the lower limb motor to rotate, so that the first worm wheel 2-3 matched and connected with the first worm 2-4 drives the lower front foot 2-2 (lower rear foot 3-2) to rotate, the lower front foot 2-2 (lower rear foot 3-2) is rotated and folded relative to the upper front foot 2-1 (upper rear foot 3-1), the spherical outer edge of the lower front foot 2-2 (lower rear foot 3-2) is contacted with the ground, the spherical outer edges of the lower front foot 2-2 and the lower rear foot 3-2 form a rolling non-closed sphere, in addition, the lower body motor arranged on the main body 1 drives the upper front foot 2-1 (upper rear foot 3-1) to rotate, thereby adjusting the position of the forefoot and hindfoot portions to obtain a rolling-facilitating spherical structure, as shown in fig. 2; meanwhile, in the middle foot part, the rotating platform 5-1 is in matched transmission with the third worm 5-5 through the third worm wheel 5-3, so that the rotating platform rotates around a vertical shaft 5-6 on the main body 1, the rotating axis of the middle foot upper limb 4-1 is vertical to the rotating axis of the front foot upper limb 2-1 (the rear foot upper limb 3-1), the middle foot lower limb 4-2 can be symmetrically positioned at two sides of the main body 1, and meanwhile, the middle foot lower limb 4-2 is rotationally folded relative to the middle foot upper limb 4-1 (the same rotating folding mode as that of the front foot lower limb 2-2 relative to the front foot upper limb 2-1), so that the outer edge of the middle foot lower limb 4-2 forms a non-closed spherical lower part, as shown in fig. 2, and finally, the rolling state is completed through deformation. At the moment, the robot is powered by the extension and contraction of the lower power foot limbs of the power foot part, as shown in the figures 5-7, the two movable sliding blocks 6-5 are controlled by the screw rod motor to rotate through driving the screw rods 6-7 to move outwards or inwards symmetrically at the same time, so that the extension and contraction of the lower power foot limbs 6-3 are controlled by the upper power foot limbs 6-2, the upper power foot limbs 6-1 are driven by the upper power foot limb motor to rotate, and the lower power foot limbs 6-3 are controlled to rotate at a certain angle relative to the swing platform 6-4 by the upper power foot limbs 6-1.
In the invention, as shown in fig. 6, the left part and the right part of the screw rod 6-7 are provided with threads with different turning directions (the middle can be separated by a nut and other devices), one part is left-handed and the other part is right-handed, when the screw rod motor on the swing platform 6-4 drives the screw rod 6-7 to rotate, because the screw rod 6-7 can only rotate towards one direction, the two moving sliding blocks can simultaneously and symmetrically move outwards or inwards through the threads with different turning directions. As shown in fig. 7, the extension power foot 6 is on the left side, and the retraction power foot 6 is on the right side. After the power foot 6 extends out, a thrust force is given to the ground, and the machine obtains a reaction force and is pushed by the power foot to roll forwards, as shown in fig. 8.
During rolling, in the process that the power foot 6 extends out, the swing platform is not static relative to the main body, but swings at an opposite angular speed relative to the main body (the swing platform 6-4 is driven to rotate around the horizontal shaft 1-1 by the horizontal shaft driven by the motor arranged on the main body, which belongs to the conventional technical means and is not detailed), as shown in fig. 6, the power foot part swings around the horizontal shaft relative to the main body at an angle in the rolling process, so that the power foot can effectively and continuously push the ground when extending out every time, and the power foot can not be in short-time contact with the ground due to rolling of the machine, and the power foot part can continuously roll and move quickly.
The invention can realize conventional advancing and rolling advancing, and when the machine advances conventionally, the linear advancing and the rotary motion of the machine can be realized by utilizing the three pairs of feet of the front group, the rear foot and the middle foot to be matched with each other; when the robot rolls, the front foot, the rear foot and the middle foot are respectively folded and deformed, the arc-shaped outer edges of the lower limbs of the four pairs of feet form a non-closed sphere which is favorable for rolling, then a thrust force is exerted on the ground by the extension of the power foot in the rolling process to obtain a reaction force to push the robot to roll, and the power foot 6 can always effectively pedal the ground to obtain the reaction force to keep the robot continuously roll through the swing of the swing platform 6-4 in the rolling process of the robot.
In the invention, the installation positions of the motors are not shown in the attached drawings, and the connection relation and the installation mode between the output shafts of the motors and each part belong to the conventional technical means, so the detailed description is not provided.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
