With the continuous development of science and technology, the intensity of industrial automation is higher and higher, and the manufacturing develops into a trend towards more flexible direction, and the robot is the flexible arm of multiaxis linkage, collects flexibility, precision, intellectuality in an organic whole, needs very high positioning accuracy. The robot needs to detect the position precision before working, so as to ensure the working precision of the robot. The traditional robot precision verification process is extremely complex, is easily influenced by human factors, and is not high in accuracy. Therefore, an efficient and accurate robot precision verification method is needed.
In this embodiment, a robot precision verification system is provided, fig. 1 is a schematic structural diagram of a robot precision verification system according to an embodiment of the present application, and as shown in fig. 1, the robot precision verification system includes an execution module 100, a verification module 200, and a judgment module 200, where the execution module 100 is disposed at a terminal of a robot, where: the verification module 200 is provided with an analog path; the execution module 100 is configured to receive a control instruction, and move to a position corresponding to the simulation path based on the control instruction; the judging module 200 is configured to judge whether the executing module 100 can pass through the simulation path, and determine the precision of the robot based on the judgment result.
Specifically, in an actual application scenario of the robot, various different tools, such as a welding gun of an industrial robot, a surgical instrument of a surgical robot, etc., may be installed at the end of the robot according to business requirements, and after the tool is replaced or adjusted, the position of the actual working point of the robot relative to the end of the robot may change. Therefore, the execution module 100 is disposed at the end of the robot to simulate the position of the actual working point when the robot works. The verification module 200 is configured to simulate a working object of the robot, where the simulation path simulates an entire path through which the working object is to be processed in an actual working process of the robot, and the robot needs to adjust its pose when passing through the path. For example, in a surgical robot application scenario in the field of medical instruments, the verification module 200 is to verify the precision of an execution path of a surgical robot during a working process, and both the position and the posture of a surgical robot tip may affect the precision. The simulation path set by the verification module 200 is not only used for confirming the space position of the tail end of the surgical robot, but also used for simulating the focus of different positions of a patient in the surgery. The determination module 200 determines the accuracy of the robot by performing the simulated path-through of the module 100 in the verification module 200. Furthermore, the execution module 100 of the robot may simulate the path by a physical mechanical component penetrating the simulated path, for example, a probe penetrating the simulated path to the bottom of the verification module 200; it may also be that a non-physical mechanical structure traverses the analog path, such as the execution module 100 emitting a laser and the laser tube beam traversing the analog path to the bottom of the verification module 200.
Through the device, the robot precision verification system of the embodiment of the application controls the execution module 100 to enter the simulated aperture in the verification module 200 by setting the execution module 100, the verification module 200 and the judgment module 300, and determines the precision of the surgical robot by acquiring the passing condition of the execution module 100 in the simulated aperture through the judgment module 300, so that the verification efficiency and the verification accuracy of the robot precision are improved.
In some of these embodiments, the simulated path includes holes of different diameters, different angles, and different depths. Specifically, the robot executes corresponding actions based on the acquired control commands during the working process. Since the jig is generally disposed at the end of the robot, the robot needs to adjust the position and posture of the end when performing an operation. The fixture is used as a tool to assist in controlling position and/or motion. The holes with different diameters, different angles and different depths are arranged in the verification module, and the execution modules of the robot, such as jigs and the like, are controlled to enter the holes, so that whether the pose of the jig meets the precision standard or not in the process of executing different control instructions of the robot can be judged, and the precision of the robot is determined.
In one embodiment, the simulated path may be provided with different levels of precision, each level of precision corresponding to one or more diameters, angles, and depths of the holes. When each precision level corresponds to a hole with a diameter, an angle and a depth, the diameter of the hole represents the current verification precision. When each precision grade corresponds to holes with the same diameter and various angles and depths, the precision of the current robot is corresponding to the precision grade of the hole only when the execution module can pass through all the holes with the same diameter. The robot precision verification process can be verified in the sequence from high precision grade to low precision grade, and can also be verified in the sequence from low precision grade to high precision grade. Taking the sequence from low to high according to the precision grade, namely the sequence from large to small according to the diameter of the hole as an example, the precision verification process of the robot is as follows: when the execution module passes through all holes of the current precision grade, the current robot precision grade is determined to be the first precision grade, the execution module is controlled to enter the holes corresponding to the second precision grade, wherein the second precision grade is higher than the first precision grade, and the higher the grade is, the higher the robot precision is. And if the execution module fails to pass through a certain hole in the second precision grade, determining that the precision grade of the robot is the first precision grade. And if the execution module can pass through all holes corresponding to the second precision grade, determining that the current robot precision grade is the second precision grade, controlling the execution module to enter the holes corresponding to the higher precision grade, and determining the precision grade of the robot again according to the passing condition of the execution module until the execution module cannot pass through one hole. By setting the method for setting various holes under the same precision grade, the robot can complete various specified actions under the same precision verification condition, and the accuracy of precision verification is ensured. The robot precision verification method has the advantages that the robot precision verification efficiency is guaranteed by automatically verifying to a higher precision grade after the control execution equipment reaches a certain precision standard.
In one embodiment, when the robot precision verification method is applied to a surgical robot scene, the near end of the hole, namely the entrance of the hole corresponding to the execution equipment, can be used for simulating a craniotomy point of a patient in a surgical process; the distal end of the aperture, i.e., the exit of the aperture corresponding to the performing device, may be used to simulate a target site during a surgical procedure, i.e., a location of a lesion at a target site on a patient. The holes with different diameters are used for verifying the precision of the surgical robot, and the holes with different depths and different angles are used for simulating target points and surgical paths of different positions of a patient. The precision verification of the surgical robot in the medical scene is realized.
In one embodiment, the execution module includes a laser transmitter configured to transmit laser light to a set hole along a set angle based on the control instruction.
In one embodiment, the determining module includes a laser receiver for receiving the laser light passing through the hole and determining the accuracy of the robot based on the laser light receiving condition.

Holes with different diameters, different angles and different depths are arranged on the precision verification tool, and the holes are simulation paths. And a laser receiver is fixed at the bottom of each hole. The laser receiver is a judging module for judging whether the laser penetrates the verification module. The surgical robot obtains the position of each hole through positioning, then the surgical robot automatically moves the laser emitter, verification is carried out according to the diameter of the hole from small to large, the diameter of the hole corresponds to the precision grade of the robot, and the smaller the diameter of the hole is, the higher the precision of the robot is. Whether the precision verification passes or not can be judged by judging whether the laser receiver receives light, for example, if the light beam emitted by the laser emitter can pass through all holes with different angles and different depths of a certain diameter d, the verification precision of the surgical robot is represented to be less than or equal to d. When other non-entity precision verification modes are adopted, the judgment module is correspondingly adjusted to be adaptive to the non-entity mode adopted by the execution module.
In one embodiment, the execution module comprises a probe, and the probe is used for penetrating through a set hole along a set angle based on the control command.

Through the steps, the robot precision verification system provided by the embodiment of the application adopts the precision verification tool to simulate focuses and operation paths at different positions of a human body, realizes automatic verification of the precision of the surgical robot through the laser sensor, and improves the efficiency and accuracy of precision verification of the surgical robot.
In one embodiment, the present application provides a method for verifying the accuracy of a surgical robot. The method is realized based on the surgical robot precision verification device of the embodiment of the application. Specifically, this surgical robot precision verifying attachment includes: the device comprises a surgical robot, a tail end tool, a sensor structural part, a laser transmitter, a slit plate, a precision verification tool and precision verification work. The end tool is arranged at the tail end of the mechanical arm of the surgical robot and can be used for installing and replacing the surgical tool according to actual needs. The laser emitter is fixed on the end tool of the surgical robot through a sensor structural part, and the sensor structural part has a fine adjustment function and can adjust the position and the direction of a laser emitter beam. The fine adjustment function can be manually adjusted through a knob on a sensor structural member, and can also be adjusted through other control equipment such as computer equipment or a single chip microcomputer. Preferably, the laser transmitter may employ a fiber laser. The slit plate is disposed in a beam propagation direction of the laser transmitter to limit a diameter of the laser beam. The precision verification tool is provided with holes with different diameters, different angles and different depths, one end of each hole, which is far away from the laser transmitter, is provided with a laser receiver, and when the laser receiver receives an optical signal, the laser beam is determined to pass through the current hole. The laser receiver can adopt a photoelectric detector such as a photomultiplier tube to convert a received optical signal into an electric signal, and a laser receiving result is represented by the change of the electric signal. Furthermore, the laser receiver is realized in the form of a detection circuit comprising a photo resistor. The specific connection relationship of the detection circuit is not particularly limited in this application.
In the precision verification process of the surgical robot, the surgical robot controls the end tool to finely adjust the position and the posture of the laser emitter by adjusting the structural part of the sensor according to the received precision verification instruction. Specifically, the laser transmitter is moved to a preset position and the posture of the laser transmitter is adjusted according to a control instruction, so that the laser transmitter is adapted to the angle and the depth of the current hole of the precision verification tool. And after the pose of the laser emitter is adjusted, emitting a laser beam, and injecting the laser beam into the current corresponding hole through the slit plate. The diameter of the hole represents the precision, and the angle and the depth of the hole are used for better simulating the position of the focus of the patient in the actual operation process. The laser receiver is arranged at the bottom of the hole of the precision verification tool, if the laser beam is received by the laser receiver of the current hole, the fact that the laser beam penetrates through the current hole is indicated, the precision requirement is met, and then the laser receiver is controlled to move to the position of the next hole and the pose is adjusted to conduct precision detection. If the laser beam is not received by the laser receiver of the current hole, the precision of the surgical robot does not reach the precision requirement corresponding to the current hole diameter. If the laser beam can pass through all holes with the same diameter and different depths and different angles, the precision of the surgical robot can meet the requirement of the precision corresponding to the diameter of the current hole. The precision verification process can be used for verifying from high precision to low precision and also can be used for verifying from low precision to high precision. For example, in the process of verifying from high precision to low precision, the laser emitter is controlled to emit a laser beam to the hole with the smallest diameter, if the laser receiver receives an optical signal at the moment, the laser penetrates through the hole, the precision of the surgical robot is the same as the precision of the mark of the hole with the smallest diameter at the moment, and the precision verification process is stopped; if the laser receiver does not receive the optical signal at the moment, the laser does not penetrate through the hole, the precision of the surgical robot is smaller than the precision marked by the hole, the laser transmitter is controlled to move to the position above the hole with the larger diameter, the position and the posture of the laser transmitter are adjusted, and the laser beam is transmitted again to carry out precision verification until the laser beam passes through all holes with the same diameter and different depths and different angles. By adopting the method of verifying from high precision to low precision, the higher precision verification speed can be obtained. For another example, in the process of verifying from low precision to high precision, the laser transmitter is controlled to transmit a laser beam to the hole with the largest diameter, if the laser receiver receives an optical signal at this time, it is stated that the laser penetrates through the hole, at this time, the precision of the surgical robot can reach the precision of marking the hole with the largest diameter, then the laser transmitter is controlled to move to the upper side of the hole with the smaller diameter, the position and the posture of the laser transmitter are adjusted, the laser beam is transmitted again for precision verification, until the laser receiver receives the optical signal, it is stated that the laser beam cannot penetrate through the hole with the current diameter at this time, and the precision of the surgical robot is the same as the precision of marking the hole with the previous diameter. By adopting the method from low precision to high precision verification, the situations that the laser cannot penetrate through the hole and the precision verification tool is ablated can be effectively reduced, the service life of the precision verification tool is prolonged, and the precision verification cost is reduced. In one embodiment, the precision verification step length can be set, and when the precision verification level is selected, the precision level span with a larger step length is adopted first, and then the precision level span with a smaller step length is adopted, so that the quick and accurate selection of the precision verification level is realized. By setting the precision verification step length, the precision verification speed is increased, and the service life of the precision verification tool is prolonged.
