How it works?
PiCrawler should take appropriate action based on the keyboard characters read. The lower() function converts
upper case characters into lower case characters, so that the letter remains valid regardless of case.
while True:
key = readchar.readkey()
key = key.lower()
if key in('wsad'):
if 'w' == key:
crawler.do_action('forward',1,speed)
elif 's' == key:
crawler.do_action('backward',1,speed)
elif 'a' == key:
crawler.do_action('turn left',1,speed)
elif 'd' == key:
crawler.do_action('turn right',1,speed)
sleep(0.05)
show_info()
elif key == readchar.key.CTRL_C or key in readchar.key.ESCAPE_SEQUENCES:
print("\n Quit")
break
