Member Data Documentation

boundaryVelocity

float boundaryVelocity = 150

Speed the profile is floored at [mm/s].

Needed at the start: a GlobalTrajectory assigns a velocity to a position, so v(s = 0) = 0 is a fixed point – the controller looks up zero at the pose it is standing in, commands zero, and the robot never leaves the start.

cornerLimit

float cornerLimit = 35

cornerVelocity

float cornerVelocity = 200

enableRampingCorners

bool enableRampingCorners = true

enableRampingEnd

bool enableRampingEnd = true

enableRampingStart

bool enableRampingStart = true

goalVelocity

float goalVelocity = 10

Speed the profile is allowed to fall to at the goal [mm/s].

The start's argument does not apply here: nothing has to get the robot moving again once it is at the goal, and a floor of boundaryVelocity there is precisely what it overshoots on. The feed-forward tracks the profile up to the last waypoint, so the robot arrives at the goal still commanded at that speed; the controller's final-segment law then steps the demand down in a single cycle and the command slew needs v^2 / (2 a) of run-out to absorb it – measured at 45-59 mm on ARMAR-7 with the historical 150 mm/s.

Kept above zero rather than at it, so the fixed-point argument cannot bite here either if the robot is nudged back onto the tail of the profile.

inCollisionDistanceThresholdForRecovery

float inCollisionDistanceThresholdForRecovery {100.0F}

Maximum distance [mm] to search for a valid recovery position when robot starts in collision.

maxVel

core::TwistLimits maxVel {.linear = 200.F, .angular = 0.2F}

max velocity

minVel

core::TwistLimits minVel {.linear = 0.F, .angular = 0.F}

navigateCloseAsPossible

bool navigateCloseAsPossible {false}

If true and the goal is not reachable, navigate to the closest reachable position instead of failing.

parametrization

TrajectoryParametrization parametrization {TrajectoryParametrization::Ramping}

How the planned velocity profile is (re-)assigned before execution.

rampLength

float rampLength {1000}
