exotica_core_task_maps

This package contains a selection of commonly used TaskMaps. These are either functions of configuration phi(q) or functions of the full state and control phi(x,u). They also implement partial derivatives (Jacobian / Hessian).

TaskMaps that support analytical Hessians

• ContinuousJointPose
• ControlRegularization
• Distance
• EffFrame
• EffOrientation
• EffPosition
• EffPositionXY
• JointLimit
• JointPose
• PointToPlane => Can also be interpreted as "EffPositionZ"

TaskMap that do not yet have analytical Hessians (and thus default to Gauss-Newton approximation)

• [ ] AvoidLookAtSphere
• [ ] CenterOfMass => also the first link ("base") mass is currently ignored :'(
• [ ] CollisionCheck
• [ ] CollisionDistance
• [ ] EffAxisAlignment
• [ ] EffBox
• [ ] EffVelocity
• [ ] GazeAtConstraint
• [ ] InteractionMesh
• [ ] JointAccelerationBackwardDifference
• [ ] JointJerkBackwardDifference
• [ ] JointTorqueMinimizationProxy
• [ ] JointVelocityBackwardDifference
• [ ] JointVelocityLimit
• [ ] JointVelocityLimitConstraint
• [ ] Manipulability
• [ ] PointToLine
• [ ] QuasiStatic
• [ ] SmoothCollisionDistance
• [ ] SphereCollision
• [ ] SumOfPenetrations

TaskMaps known to have discontinuous gradients for NLPs

Time-indexed task maps

• [ ] EffVelocity
• [ ] JointVelocityLimit
