-Supported states are: ''​EarlyStance'',​ ''​LateStance'',​ ''​LiftOff'',​ ''​Swing'',​ ''​Landing''​. See the gait tutorial ​ for an example. ​+Supported states are: ''​EarlyStance'',​ ''​LateStance'',​ ''​LiftOff'',​ ''​Swing'',​ ''​Landing''​. 
 + 
 +The current state of a leg is defined through its current relative sagittal foot position (''​sagittal_pos''​) and the normalized load (''​leg_load''​). Transitions between states are defined as follows (see also public attributes below): 
 +  * ''​Landing''​ -> ''​EarlyStance''​ occurs if ''​leg_load''​ is above **stance_load_threshold**. 
 +  * ''​EarlyStance''​ -> ''​LateStance''​ occurs if ''​sagittal_pos''​ is below **late_stance_threshold**. 
 +  * ''​LateStance''​ -> ''​LiftOff''​ occurs if contralateral ''​leg_load''​ is above **stance_load_threshold** or ''​sagittal_pos''​ is below **liftoff_threshold**. 
 +  * ''​LiftOff''​ -> ''​Swing''​ occurs if ''​leg_load''​ is below **swing_load_threshold**. 
 +  * ''​Swing''​ -> ''​Landing''​ occurs if ''​sagittal_pos''​ is above **landing_threshold**.
