Before running the tasks ensure that all the files in the scripts folder are executable: $chmod +x * Also use catkin_make to build the packages and source setup the workspace after that

Tasks completed:

Task#1:

Youtube link: https://youtu.be/koBg9EcM_EM

To check this task, run these:

$roslaunch embedathon2021 task1.launch
$rosrun embedathon2021 task1.py

Task#2:

Youtube link: https://youtu.be/hUf_AHrWGKU

To check this task, run these:

$roslaunch embedathon2021 task2.launch
$rosrun embedathon2021 task2.py

Task#3:

$roslaunch embedathon2021 task3.launch
$rosrun teleop_twist_keyboard teleop_twist_keyboard.py

$roslaunch embedathon2021 temp.launch
$rosrun embedathon2021 task3-subtask1.py

  • 3.2.2: https://youtu.be/o9VWxZO8c6Y

    To check this task, there are 2 ways we tried:

    • Method 1 
      $roslaunch embedathon2021 task3.launch
$rosrun embedathon2021 task3.py
    • Method 2 
      $roslaunch embedathon2021 task3.launch
$roslaunch embedathon2021 bug2.launch
      The python files used in this method are: bug_algo_2.py , follow_wall.py and go_to_point.py

  • To integrate 3.2.1 and 3.2.2 (Method 1):

    • comment self.shutdown() and other statements that cause break in loop in task3-subtask1.py file
    • copy the libraries and class from task3.py to task3-subtask1.py
    • copy the line self.sub1 = rospy.Subscriber("/scan", LaserScan, self.callback) from init in task3.py to task3-subtask1.py
    • Copy these lines from main of task3.py to main of task3-subtask1.py file 
       rclass = Moving() 
 rclass.linear_vel = 0.1
 rclass.go_to_goal(-25)

  • NOTE: Task 3.3 can be done using 3.2.2 (Method 1 or 2), but the initial and final destination points need to be changed
