Mobile industrial measuring robot based on SLAM technology
Technical Field
The utility model belongs to the technical field of the robot and specifically relates to mobile industrial measurement robot based on SLAM technique.
Background
The traditional industrial measurement method is mainly divided into an on-line measurement method and an off-line measurement method, wherein the on-line measurement method is to carry out direct measurement on an industrial production line; the off-line measurement means that after the production operation is finished, the part is transferred to a special measuring device for measurement. The on-line measurement has the advantages of high measurement efficiency and capability of carrying out real-time measurement under the condition of not influencing production. However, the online measurement has the following disadvantages:
1. because the environment during measurement can not be guaranteed and the measurement result needs to be generated quickly, the measurement precision of online measurement is not high, and the method is only suitable for occasions requiring low measurement precision;
2. production equipment of many factories does not leave an interface for on-line measurement when being purchased, so that a new measuring device can be additionally arranged on the basis of the original equipment at a higher cost;
3. the on-line measuring equipment can only be used for one production equipment, so that when the measuring requirement changes dynamically, the waste of measuring resources is caused.
Although the off-line measurement can be more accurate, the off-line measurement also has the following disadvantages:
1. in order to ensure the stability of the measuring environment, the offline measurement needs to firstly transfer the parts from the space of the production equipment to the space of the measuring equipment, and the measuring efficiency is low;
2. in addition, during the transferring process of the parts, the parts are often transferred manually, and for many parts with strict measurement requirements, manual participation can bring uncertain factors to the measurement, or in the case that some production environments are not suitable for people to enter, a robot is required to replace the manual work.
