Abstract
The utility model relates to an auxiliary screen indication manipulator for teaching, and belongs to the technical field for development of teaching tools. A teacher can conveniently teach only by controlling an auxiliary handle on a platform to make the auxiliary screen indication manipulator move along with the handle to indicate a target position. The auxiliary screen indication manipulator is composed of a retractable indication portion, a mechanism movement portion and a control sensing portion. An ARDUINO electronic platform and a three-axis gyroscope sensor are utilized for cooperation with development, steering engines and a motor are controlled to rotate and the retractable indication portion is controlled to retract through movement of the auxiliary handle, and thus the follow-up auxiliary screen indication manipulator is enabled to move. A mechanism motion portion is formed by three steering engines and one motor, wherein the steering engines are used for driving an indication arm to rotate a certain angle to electrically drive up and down mobile devices to make the auxiliary screen indication manipulator move. The control sensing portion is formed by the ARDUINO electronic platform and the three-axis gyroscope sensor.
Description
Technical field
The utility model relates to a kind of teaching assist type screen instruction mechanical arm, belongs to the technical field of teaching aid exploitation.
Background technology
At present, the colleges and universities that China is nearly all and most of secondary school can use projector and carry out PPT teaching demonstration in daily teaching, because projection screen area is larger, average height is higher, and teacher will use the auxiliary explanation of the marking toolses such as teacher's pointer while needing explanation in detail.Marking tools such as tradition teacher's pointer etc. needs teacher tightly on giant-screen, to indicate one by one by holding, and operating process easily stops project content on screen, affects teacher's education informations transmission and affects student's efficiency of listening to the teacher; The marking toolses such as tradition teacher's pointer need teacher to have significantly hand motion, increase teacher's classroom amount of exercise, consume teacher's muscle power.
Aspect patent, retrieve with related keywords such as assist type screen instruction mechanical arms, not yet there is Patents.
Utility model content
In view of the deficiencies in the prior art, the object of the present invention is to provide a kind of assist type screen instruction mechanical arm, utilize ARDUINO e-platform and three-axis gyroscope sensor to coordinate exploitation, by stretching of the auxiliary motion control steering wheel of handle and the rotation of motor and instruction telescopic section, realize a kind of assist type screen instruction robot device motion of trailing type.
Assist type screen instruction mechanical arm of the present invention is made up of the indicating section that stretches, mechanism kinematic part and control sensing part three parts.Flexible indicating section is by syllogic electric expansion bar construction.Mechanism kinematic part is made up of three steering wheels and a motor, steering wheel is used for driving instruction arm to turn an angle, electronic drive moves up and down device and moves assist type screen instruction mechanical arm, controls sensing part and is made up of ARDUINO e-platform and three-axis gyroscope sensor.
Described syllogic electric expansion rod is by its telescopic of electric signal control.
The described steering wheel control assist type screen instruction mechanical arm pivot arm anglec of rotation.
Described mobile device is made up of motor, slide block, slide rail and pulley, drives assist type screen instruction mechanical arm to move up and down.
Described ARDUINO e-platform is used for writing control program and receives three-axis gyroscope sensor signal, controls the motion of steering wheel and motor.
Described three-axis gyroscope installation of sensors is on auxiliary handle.
Described auxiliary handle is fixed on support.
The invention solves all colleges and universities of China and most of secondary school in projector teaching process, with traditional teacher's pointer complex operation, affect the problems such as efficiency of teaching.Assist type screen instruction mechanical arm utilizes servo-actuated control principle, and accurately localizing objects position, raises the efficiency.
Brief description of the drawings
Fig. 1 assist type screen instruction of the present invention mechanical arm hardware unit schematic diagram
In figure, 1 is syllogic electric expansion rod, and 2 is steering wheel a, and 3 is steering wheel b, and 4 is steering wheel c, and 5 is slide block, and 6 is belt, and 7 is ARDUINO e-platform, and 8 is auxiliary handle, and 9 is support, and 10 is slide rail, and 11 is motor.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
Assist type screen instruction mechanical arm described in the utility model, as shown in Figure 1, concrete operational process is: after assist type screen instruction mechanical arm switches on power, ARDUINO e-platform 7 brings into operation.Teacher, in teaching process, controls the motion all around of auxiliary handle 8, realizes the control to assist type screen instruction mechanical arm.In the time that auxiliary handle 8 moves, ARDUINO e-platform 7 receives after the signal that the three-axis gyroscope sensor that is positioned on auxiliary handle 8 spreads out of, carry out internal processes operation by pre-set program, the operation of output signal drive motor 11, even if assist type screen instruction mechanical arm moves up and down at the slide block 5 of driven by motor mobile platform, after arrival assigned address, stop.Behind definite position, then utilize the pre-set program of ARDUINO to make mechanical arm rotation under steering wheel a2, steering wheel b3, steering wheel c4 drive, arrive target and stop.Behind definite position, by button, regulate the length of electric expansion rod by assisting the button on handle to control separately its collapsing length, finally determine the cooperatively interacted servo-actuated instruction of PPT in teaching of its assigned address, above action.Teacher only need control at dais auxiliary handle, and the servo-actuated target location that is indicated to of realizing assist type screen instruction mechanical arm, can conveniently impart knowledge to students.
