Detailed Description

Typedef Documentation

◆ Grippers_t

typedef std::vector<GripperPtr_t> hpp::manipulation::graph::helper::Grippers_t

◆ Handles_t

typedef std::vector<HandlePtr_t> hpp::manipulation::graph::helper::Handles_t

◆ Object_t

typedef std::tuple<PlacementConstraint_t, Handles_t, std::size_t> hpp::manipulation::graph::helper::Object_t

Tuple representing an object as follows:

  • PlacementConstraint_t constraint to place the object
  • Handles_t list of handles of the object
  • std::size_t the index of this tuple in Objects_t.
    Note
    the index must be unique, as object equallity is checked using this index.

◆ Objects_t

typedef std::vector<Object_t> hpp::manipulation::graph::helper::Objects_t

◆ PlacementConstraint_t

typedef std::tuple<ImplicitPtr_t, ImplicitPtr_t, LockedJoints_t> hpp::manipulation::graph::helper::PlacementConstraint_t

◆ Rules_t

typedef std::vector<Rule> hpp::manipulation::graph::helper::Rules_t

Function Documentation

◆ createEdges()

template<int gCase>
Edges_t hpp::manipulation::graph::helper::createEdges ( const std::string &  forwName,
const std::string &  backName,
const StatePtr_t &  from,
const StatePtr_t &  to,
const size_type &  wForw,
const size_type &  wBack,
const FoliatedManifold &  grasp,
const FoliatedManifold &  pregrasp,
const FoliatedManifold &  place,
const FoliatedManifold &  preplace,
const bool  levelSetGrasp,
const bool  levelSetPlace,
const FoliatedManifold &  submanifoldDef = FoliatedManifold() 
)

Create edges according to the case. gCase is a logical OR combination of GraspingCase and PlacementCase

When an argument is not relevant, use the default constructor of FoliatedManifold

◆ createLoopEdge()

EdgePtr_t hpp::manipulation::graph::helper::createLoopEdge ( const std::string &  loopName,
const StatePtr_t &  state,
const size_type &  w,
const bool  levelSet,
const FoliatedManifold &  submanifoldDef = FoliatedManifold() 
)

◆ graphBuilder() [1/2]

void hpp::manipulation::graph::helper::graphBuilder ( const ProblemSolverPtr_t &  ps,
const Objects_t &  objects,
const Grippers_t &  grippers,
GraphPtr_t  graph,
const Rules_t &  rules = Rules_t() 
)

Fill a Graph

Note
It is assumed that a gripper can grasp only one handle and each handle cannot be grasped by several grippers at the same time.
Parameters
[in,out]graphmust be an initialized empty Graph.

◆ graphBuilder() [2/2]

GraphPtr_t hpp::manipulation::graph::helper::graphBuilder ( const ProblemSolverPtr_t &  ps,
const std::string &  graphName,
const Strings_t &  griNames,
const std::vector< ObjectDef_t > &  objs,
const Strings_t &  envNames,
const Rules_t &  rules,
const value_type &  prePlaceWidth = 0.05 
)

◆ graspManifold()

void hpp::manipulation::graph::helper::graspManifold ( const GripperPtr_t &  gripper,
const HandlePtr_t &  handle,
FoliatedManifold &  grasp,
FoliatedManifold &  pregrasp 
)

Create a waypoint edge taking into account:

  • grasp
  • placement
  • preplacement Create a waypoint edge taking into account
  • grasp
  • pregrasp
  • placement

◆ merge_nc()

NumericalConstraints_t hpp::manipulation::graph::helper::merge_nc ( const NumericalConstraints_t &  a,
const NumericalConstraints_t &  b 
)

◆ relaxedPlacementManifold()

void hpp::manipulation::graph::helper::relaxedPlacementManifold ( const ImplicitPtr_t  placement,
const ImplicitPtr_t  preplacement,
const LockedJoints_t  objectLocks,
FoliatedManifold &  place,
FoliatedManifold &  preplace 
)

The placement foliation constraint is built locked joints It is faster than strictPlacementManifold but the foliation parametrisation is redundant.

◆ strictPlacementManifold()

void hpp::manipulation::graph::helper::strictPlacementManifold ( const ImplicitPtr_t  placement,
const ImplicitPtr_t  preplacement,
const ImplicitPtr_t  placementComplement,
FoliatedManifold &  place,
FoliatedManifold &  preplace 
)

The placement foliation constraint is built using hpp::constraints::ConvexShapeMatcherComplement
