Typedef Documentation

◆ JerkSigns

◆ Limits

Enumeration Type Documentation

◆ ControlInterface

enum class ruckig::ControlInterface
strong
Enumerator
Position 

Position-control: Full control over the entire kinematic state (Default)

Velocity 

Velocity-control: Ignores the current position, target position, and velocity limits.

◆ DurationDiscretization

enum class ruckig::DurationDiscretization
strong
Enumerator
Continuous 

Every trajectory synchronization duration is allowed (Default)

Discrete 

The trajectory synchronization duration must be a multiple of the control cycle.

◆ Result

Result type of Ruckig's update function.

Enumerator
Working 

The trajectory is calculated normally.

Finished 

Trajectory has reached its final position.

Error 

Unclassified error.

ErrorInvalidInput 

Error in the input parameter.

ErrorTrajectoryDuration 

The trajectory duration exceeds its numerical limits.

ErrorPositionalLimits 

The trajectory exceeds the given positional limits (only in Ruckig Pro)

ErrorExecutionTimeCalculation 

Error during the extremel time calculation (Step 1)

ErrorSynchronizationCalculation 

Error during the synchronization calculation (Step 2)

◆ Synchronization

enum class ruckig::Synchronization
strong
Enumerator
Time 

Always synchronize the DoFs to reach the target at the same time (Default)

TimeIfNecessary 

Synchronize only when necessary (e.g. for non-zero target velocity or acceleration)

Phase 

Phase synchronize the DoFs when possible, else fallback to "Time" strategy.

None 

Calculate every DoF independently.
