#=========================== YOUR CODE HERE ===========================
# Instructions: construct the state machine by adding the states that
# you have implemented.
# Below is an example how to add a state:
#
# smach.StateMachine.add('SEARCH',
# PreemptableState(search,
# input_keys=['front_min', 'clearance'],
# output_keys=['velocity'],
# outcomes=['found_obstacle']),
# transitions={'found_obstacle': 'ANOTHER_STATE'})
#
# First argument is the state label, an arbitrary string
# (by convention should be uppercase). Second argument is
# an object that implements the state. In our case an
# instance of the helper class PreemptableState is
# created, and the state function in passed. Moreover,
# we have to specify which keys in the userdata the
# function will need to access for reading (input_keys)
# and for writing (output_keys), and the list of possible
# outcomes of the state. Finally, the transitions are
# specified. Normally you would have one transition per
# state outcome.
#
# Note: The first state that you add will become the initial state of
# the state machine.

#=========================== YOUR CODE HERE ===========================
# Instructions: construct the state machine by adding the states that
# you have implemented.
# Below is an example how to add a state:
#
# smach.StateMachine.add('SEARCH',
# PreemptableState(search,
# input_keys=['front_min', 'clearance'],
# output_keys=['velocity'],
# outcomes=['found_obstacle']),
# transitions={'found_obstacle': 'ANOTHER_STATE'})
#
# First argument is the state label, an arbitrary string
# (by convention should be uppercase). Second argument is
# an object that implements the state. In our case an
# instance of the helper class PreemptableState is
# created, and the state function in passed. Moreover,
# we have to specify which keys in the userdata the
# function will need to access for reading (input_keys)
# and for writing (output_keys), and the list of possible
# outcomes of the state. Finally, the transitions are
# specified. Normally you would have one transition per
# state outcome.
#
# Note: The first state that you add will become the initial state of
# the state machine.
