Hi @parsa07, the issue here is a mistake when the code was copied over from the course notebook to the move_bb8_square.py
file.
The error points to an unexpected indent, so check line 11. It should be in line with the previous publisher initialization, like this:
#!/usr/bin/env python
import rospy
from geometry_msgs.msg import Twist
import time
import math
class MoveBB8():
def __init__(self):
self.bb8_vel_publisher = rospy.Publisher('/cmd_vel', Twist, queue_size=1)
self.cmd = Twist()
self.ctrl_c = False
rospy.on_shutdown(self.shutdownhook)
self.rate = rospy.Rate(10)
I recommend simply deleting the contents and pasting them again making sure the alignment is correct.
