In the science fiction movies I watched when I was a child, the robots in my eyes have hands and feet just like us humans, and can do some tasks that humans cannot complete. I just stepped into the school and heard that there was no Robot Association. I felt extremely happy and felt that the world of robots was only one step away from me. After joining the Robot Association, my senior explained the concept of robots to us. A robot is a kind of robot that can run and move, can run pre-programmed programs, and can also be designed based on artificial intelligence technologySierra Leoneans Escort‘s basic actions, the robots they showed us turned out to be two Sierra Leoneans Escort A wheeled car. The car can also be called “RobSL Escortsot”. Various sensors can be added to the car to make it look like us. Sierra Leone Sugar also avoids obstacles and can handle urgent incidents in a timely manner Sierra Leoneans Sugardaddysettings.
This semester we offer the course “AVR Single Chip Sierra Leone Sugar Daddy Machine and Small Robot Production”, Sierra Leoneans Sugardaddy gives me more opportunities to interact with robots. Although Sierra Leone Sugar Daddy had eaten and participated in the Chinese educational robot competition before taking this course, it was nothing like the one we took. There are still certain differences in the programming methods used in each course. The difference is that the chips used are different. Sierra Leone Sugar The microcontroller is AT89S52, and the microcontroller used in class is atmega8. first classThe teacher taught us how to install the software, Sierra Leone Sugar driver, and how to create a makefile. The important thing is to configure the device before programming the chipSierra Leone Sugar DaddyThe fuse is (EF, C9), if the installation is not set SL Escorts equipment equipped with fuses, SL Escorts will eventually cause the fuse to lock up. So I started writing a program to display on the serial port according to the internal affairs taught by the teacher. After that, the teacher taught us about using the I/O interface to control the servo motor, servo adjustment Sierra Leoneans Sugardaddy zero, and pulse width to control the speed of the motor. Basic internal matters such as direction and direction.
With the basic knowledge behind, I have a new understanding of robots, Sierra Leone Sugar Daddy Then, the teacher Start by arranging some small tasks for usSierra Leoneans Sugardaddy. The first task is to use function calling to move the square and array to move the square. It seems that this task is super simple, but it involves a lot of knowledge. First, the servo motor must be zero-adjusted, Sierra Leone Sugar Daddy so that the robot can walk 50cm straight.
The second task is robot tactile navigation. We use whisker-shaped metal wires as the beards of the robot, so that the robot has the ability to determine the surrounding conditions through contact, just like a kitten relying on its whiskers. Perceive the surrounding conditions to achieve the goal of avoiding obstacles. There are several things to do before completing the second task: First: First, ensure thatProve that our SL Escorts circuit is correct; second, write the program according to the teacher’s task requirements; third: write the program, Download it to the microcontroller, vibrate the tentacles to see if it is consistent with the written program; fourth: let the robot run on the spot, according to the actual situation, Sierra Leone Sugar DaddyModify the parameters until they meet the tasks assigned by the teacher.
The third task is to use photoresistor for navigation (Sierra Leone Sugar photosensitive for square, photosensitive for circular). Before this task, I understood the working principle of the photoresistor by reading a bookSL Escorts. Real things are imaginary. Only after actual operation can we understand the gap between reality and Sierra Leoneans Sugardaddy reality. First build the circuit, adjust the potentiometer according to the actual intensity of light, and adjust Sierra Leoneans Escort in order to increase the photoresistorSierra Leone Sugar‘s acumen. Then observe whether the robot can determine the black line, constantly modify the program, and finally achieve the effect of the robot tracking along the black line. Sierra Leoneans Escort
The fourth task is robot infrared navigation (infrared maze, infrared circle), this time The task was very difficult. I built the circuit several times and kept checking Sierra Leoneans Escort the circuit, and finally Sierra Leoneans EscortJi saw a little bit of hope.After taking this course, I gained a lot from it. Not only did I gain knowledge, but it also taught me a kind of independent programming Sierra Leone Sugar. What’s more, as long as you have Sierra Leoneans Sugardaddy patience and perseverance, you can tame the robot in your hands!
