Abstract
The utility model relates to a robot, and especially relates to a robot capable of backing when approaching an obstacle. The robot comprises ultrasonic sensors, control circuits and a motor, and is characterized in that the ultrasonic sensors are connected with the control circuits and the motor; control switches are disposed between the control circuits and the motor; the control circuits are also provided with a power supply device; the power supply device is provide with a switch and a power supply indicating lamp; and the ultrasonic sensors detect whether an obstacle is positioned at the front, detected signals are sent to the control circuits, the control circuits receive the signals and control the control switches to operate, the motor reversely rotates after the control switches are closed, so that the robot can be prevented from impacting the obstacle. The robot is novel in design, low in cost, simple in operation, visual in demonstration and convenient to use, the problem that teaching demonstration instruments are lacking is well solved, teaching interests of students are developed, and teaching quality is improved.
Description
Technical field
The utility model has related to robot, has related in particular to a kind of robot that obstacle can retreat of meeting.
Background technology
Robot movable meets the active feature eager to learn of teenager, is deeply subject to numerous classmates' favor.Regular senior secondary school's current techique class is taken as an elective course textbook one Ben Shuzhuanjiang robot knowledge, and demonstration instrument lacks at present, and classmates can not be intuitively, the structure of overall understanding robot and just understanding the current techique of robot, cannot realize practical activity and impart knowledge to students.
Summary of the invention
The utility model aims to provide with low cost, simple to operate, and demonstrating visual a kind of meets the robot that obstacle can retreat.
Technical solution of the present utility model is:
Meet obstacle and can retreat robot, comprise ultrasonic sensor, control circuit and motor, it is characterized in that: ultrasonic sensor is connected with control circuit and motor; Between control circuit and motor, be provided with gauge tap, be also provided with electric supply installation on control circuit, described electric supply installation is provided with switch and power light.
Described ultrasonic sensor, control circuit and gauge tap are provided with several.
Described ultrasonic sensor, control circuit and gauge tap arrange two groups; Described ultrasonic sensor is HC-SR04 ultrasonic sensor, and control circuit is NE555 time base circuit, and gauge tap is electromagnetic relay.
Described ultrasonic sensor comprises ultrasonic sensor 1 and ultrasonic sensor 2; Control circuit comprises NE555
1and NE555
2, gauge tap comprises electromagnetic relay 1 and electromagnetic relay 2.
Described electric supply installation is No. 5 dry cells of 4 joint.
Described switch is button switch.
Described power light is light emitting diode.
The utility model has the advantage of:
Whether ultrasonic sensor described in the utility model detects the place ahead barrier, the signal of detection is sent to control circuit, control circuit makes gauge tap work after receiving signal, and the closed rear motor reversion of gauge tap work, makes robot avoid touching and rush barrier.Utility model of the present invention is novel in design, with low cost, simple to operate, and demonstrating visual is easy to use, solves preferably teaching demonstration instrument and lacks, and cultivates student's learning interest, has improved quality of instruction.
Accompanying drawing explanation
Fig. 1 the utility model workflow diagram.
Embodiment
Embodiment mono-
Meet obstacle and can retreat robot, comprise ultrasonic sensor, control circuit and motor, it is characterized in that: ultrasonic sensor is connected with control circuit and motor; Between control circuit and motor, be provided with gauge tap, be also provided with electric supply installation on control circuit, described electric supply installation is provided with switch and power light.
Specifically, chance obstacle can retreat the electric supply installation of robot and select No. 5 dry cells of 4 joint, and switch is selected button switch, and power work pilot lamp is selected light emitting diode; Ultrasonic sensor selects HC-SR04 ultrasonic sensor as the eyes of robot, and ultrasonic sensor comprises that ultrasonic sensor 1 and ultrasonic sensor 2 are as the front and back eyes of robot; Control circuit is selected NE555 time base circuit, comprises NE5551 and NE5552, as the brain of robot; Gauge tap is selected electromagnetic relay, and motor selects four-wheel electric toy car to make robot ambulation instrument (leg) to its process and remould (underspeeding).
Select two ultrasonic sensors to do the front and back eyes (identification has clear) of robot, design two ultrasonic sensor exchange work, the front eyes of robot have right of priority work, when power supply Kai Shi robot walks first forward, when robot walks forward, there is clear before the eyes ultrasonic sensor 1 detected activity place before robot, clear robot walks on, NE5551 exports high level, electromagnetic relay 1 work, and robot motor's energising is advanced; When having barrier above, the ultrasound wave that the ultrasound wave transmitter of ultrasonic sensor 1 sends is met barrier and is returned, and by the ultrasound wave receiving end of ultrasonic sensor 1, is received and makes NE5551 output low level, and electromagnetic relay 1 is not worked; Robot eyes ultrasonic sensor 2 is below in work, electromagnetic relay 2 work, after robot motor oppositely switches on, walking in the opposite direction, before (eyes) ultrasonic sensor 2 detected activity places in walking after robot, have clear, robot walks on, and NE5552 exports high level, electromagnetic relay 2 work, robot motor's energising is advanced; When robot walks while running into barrier in the other direction, the ultrasound wave that the ultrasound wave transmitter of ultrasonic sensor 2 sends is met barrier and is returned, ultrasound wave receiving end by ultrasonic sensor 2 receives, NE5552 output low level, electromagnetic relay 2 is not worked, robot walks and stops backward, and ultrasonic sensor 1 is started working again.At ultrasonic sensor, detecting back and forth robot movable place like this has clear to make two NE555 exchange output high level, two electromagnetic relay alternation robot motors rotating, robot is walked back and forth in its playground, form chance barrier and can retreat robot.
Briefly, at work, a march forward side work of ultrasonic sensor (two), do not work for contrary one, when the side's that advances ultrasonic sensor detects the place ahead and has barrier, another ultrasonic sensor is started working, and has completed robot and has seesawed, and can not touch and rush barrier.
