Detailed Description

template<typename ControlSignalType, typename TargetType>
class franky::VelocityWaypointMotion< ControlSignalType, TargetType >

A motion following multiple positional waypoints in a time-optimal way. Works with arbitrary initial conditions.

Template Parameters

ControlSignalType	The type of the control signal. Either franka::Torques, franka::JointVelocities, franka::CartesianVelocities, franka::JointPositions or franka::CartesianPose.
TargetType	The type of the target of the waypoints.

Constructor & Destructor Documentation

VelocityWaypointMotion()

template<typename ControlSignalType , typename TargetType >

franky::VelocityWaypointMotion< ControlSignalType, TargetType >::VelocityWaypointMotion ( std::vector< VelocityWaypoint< TargetType > >  waypoints, const RelativeDynamicsFactor &  relative_dynamics_factor = 1.0  )

inlineexplicit

Parameters

waypoints	The waypoints to follow.
relative_dynamics_factor	The relative dynamics factor for this motion. This factor will get multiplied with the robot's global dynamics factor to get the actual dynamics factor for this motion.
