2019/3 ~ 6, we had class 'Basic Mobile Project 1". Here, we have done a project which contains a robot that detects collision and changes direction.

AVR

Function Main is a code for collision detection. The function init sets up the pin of each registers which take care of motor, interrupt, PWM ... etc. In Direction, functions fix data by changing each pin separately. In Sound, it stores sound functions for each action such as forward, backward ... etc

Short summary for the main code

• Interrupt

  • If blink_led = 1, then TekBot turns led on for 1 sec.

• If both buttons are pushed at the same time (in the beginning)

  • Alerts StartSound() .
  • Enables both EN_Pins of motors.
  • EN++ --> EN is the variable that makes a distinction between beginnig and after it.

• After EN++

  • If both buttons are not cllicked

    • Go forward

  • If right button is clicked

    • Stop
    • Alerts LeftSound()
    • Go backward
    • Turn left for 90 degree (approximately)
    • blink_led++ --> variable that controls the led in timer interrupt

  • If left button is cliked

    • Stop
    • Alerts RightSound()
    • Go backward
    • Turn right for 90 degree (approximately)
    • blink_led++

  • If both buttons are clicked

    • Stop
    • Alerts BothSound()
    • Go backward
    • Turn right for 180 degree (approximately)
    • blink_led++

Testing

After testing, TekBot worked well. Thanks for everbody for helping us to finish this project.

Start TekBot by pushing both button

When left button is clicked

When right button is clicked

When both buttons are clicked
