Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 5, a pig vaccine injection robot. The pig vaccine injection robot is used in animal husbandry places, particularly pig farms, and comprises a hand-eye system and a mobile platform 6 which are sequentially overlapped from top to bottom; the hand-eye system comprises a six-degree-of-freedom serial mechanical arm 4, a binocular depth camera 1, a control box body and a contact type high-pressure injection needle 2, wherein the high-pressure injection needle 2 is installed at the execution tail end of the six-degree-of-freedom serial mechanical arm 4, and the binocular depth camera 1 is installed between the high-pressure injection needle and the execution tail end through an annular connecting piece 3; the moving platform 6 comprises two driving wheels 61 and two driven wheels 62 supporting the whole moving platform, a storage battery 610 for providing energy for the whole pig vaccine injection robot, a control circuit board for controlling the chassis to move, a vision camera 64 for providing vision navigation and a turntable 5 for driving the bottom of the six-degree-of-freedom serial mechanical arm to rotate.

After the driving motor 68 obtains the energy of the storage battery 610, a larger driving force is obtained after the speed reduction of the speed reducer 67, the driving force is provided for the driving wheel 61 through the transmission shaft 65 erected on the bearing frame 66, the driving wheel 61 drives the driven wheel to rotate together through the chain 69, and under the synergistic effect of the four wheels, the moving platform 6 can complete linear motion and turning.

Before moving, the robot loads a two-dimensional map of the pig farm and then walks on a route obtained by mission planning. The visual cameras 64 fixed at the front and the rear of the mobile platform 6 can detect various obstacles on the robot stroke through visual information to avoid collision behaviors of the robot in the walking process.

In the moving process of the robot, part of postures cannot pass through a narrow channel, at this time, the turntable 5 needs to be used for rotating, and meanwhile, the six-degree-of-freedom serial mechanical arm 4 on the turntable 5 is driven to rotate, so that the width of the whole robot is adjusted to pass through the narrow channel. Moreover, the turntable 5 can realize high-freedom motion by matching with the six-freedom-degree series mechanical arm 4, and simultaneously, under the assistance of the binocular depth camera 1 arranged at the execution tail end of the mechanical arm, under the condition of not moving the moving platform 6, the high-pressure injection needle 2 at the execution tail end can be sent to any position within an accessible range in various postures, finally the high-pressure injection needle 2 is adjusted to the injection part of the pig, then contact type high-pressure injection is carried out, and the vaccine in the liquid medicine bottle is injected into the body of the pig.

The embodiments described in this specification are merely illustrative of implementations of the inventive concepts, which are intended for purposes of illustration only. The scope of the present invention should not be construed as being limited to the particular forms set forth in the examples, but rather as being defined by the claims and the equivalents thereof which can occur to those skilled in the art upon consideration of the present inventive concept.
