A multifunctional robot for multimedia teaching assistance in classrooms

Abstract

The invention discloses a multifunctional robot for assisting multimedia teaching in classrooms. The multifunctional robot structurally comprises movable ends, a fixed end, a supporting frame, travelling wheels and telescopic ends, wherein the movable ends movably cooperate with the fixed end through the telescopic ends which are arranged at the bottoms of the movable ends correspondingly, the supporting frame and the fixed end are welded together, the two travelling wheels are arranged at the bottom of the supporting frame, a telescopic air cylinder is arranged in each telescopic end, and a driving mechanism is arranged on each movable end. According to the multifunctional robot, a rotating motor and a swinging motor cooperate with each other in each driving mechanism, each rotating motorand the corresponding swing motor are both connected to a support shaft, and a rectangular plate completes rotating and swing operation through one corresponding support shaft. On one hand, the pulling function of movable rods can be realized, and on the other hand, a surface which is not stained with chalk dust can be exposed outside by utilizing the rotation, and the other surface is closed soas to prevent the problem that difficulty exists in later cleaning due to the fact that the other surface is in direct contact with wet air and then the chalk dust is affected with damp and solidified, and meanwhile, touched equipment can be prevented from polluted.

Description

technical field [0001] The invention relates to a learning type intelligent robot, in particular, it is a multifunctional robot used for classroom multimedia teaching assistance. Background technique [0002] The current inherent model of "blackboard, chalk, teachers, and students" can no longer meet the growing teaching needs. Strengthening the service function of the classroom not only reduces the workload of teachers, but also enriches and facilitates the learning and life of students. [0003] At present, the multi-functional robots used by teachers for multimedia teaching aids all have the function of wiping the blackboard. When the robot is wiping the blackboard, the chalk dust will fly around, but most of them are concentrated on the mechanical arm that wipes the blackboard. If it is not cleaned in time If so, the chalk dust will accumulate thick dust on the mechanical arm, causing the mechanical arm to be polluted, causing the robot to contaminate textbooks or desks ...

[0002] The current inherent model of "blackboard, chalk, teachers, and students" can no longer meet the growing teaching needs, and enhancing the service function of the classroom will not only reduce the workload of teachers, but also enrich and facilitate the learning and life of students

[0003] At present, the multi-functional robots used by teachers for multimedia teaching aids all have the function of wiping the blackboard. When the robot is wiping the blackboard, the chalk dust will fly around, but most of them are concentrated on the mechanical arm that wipes the blackboard. If it is not cleaned in time If so, the chalk dust will accumulate thick dust on the mechanical arm, causing the mechanical arm to be polluted, causing the robot to contaminate textbooks or desks and other equipment when it uses other functions (organizing textbooks). The chalk dust remaining on the mechanical arm exposed to the outside air is easy to be damp and solidified, forming a hard block, which is not conducive to later cleaning
