He,
Thank you for making some time for it.
Is this your code ?
I am also using python 3
I got an error with execute the scipt:
-----------------------------------------------------------------------
Enter command> Traceback (most recent call last):
File "test06.py", line 44, in <module>
for (dir, tm) in SEQUENCE:

import threading
set_right_speed(150)
set_left_speed(105)
def cmdHandler():
global notDone
while True:
cmd = raw_input("Enter command> ").lower()
if cmd.startswith("s"):
notDone = False
break
else:
print ("Unimplemented command: %s") % cmd
cmdThread = threading.Thread(target=cmdHandler)
cmdThread.start()
def move(drct, dly):
if drct == FORWARD:
fwd()
print ("Forward")
elif drct == BACKWARD:
bwd()
print ("Backward")
elif drct == LEFT:
left()
print ("Left")
elif drct == RIGHT:
right()
print ("Right")
else:
print ("Invalid command: %s") % drct
time.sleep(dly)
stop()
notDone = True
servo(90)
mindist = 80
while notDone:
if mindist > us_dist(15):
for (dir, tm) in SEQUENCE:
move(dir, tm)
