Interface for inverse kinematics algorithms.
The InvKinSolver interface provides an interface for calculating the inverse kinematics of a device. That is to calculate such that .
By default it solves the problem beginning at the robot base and ending with the frame defined as the end of the devices, and which is accessible through the Device::getEnd() method.

pure virtual 
Returns the Tool Center Point (TCP) used when solving the IK problem.
Implemented in ParallelIKSolver, JacobianIKSolver, IKMetaSolver, PieperSolver, CCDSolver, ClosedFormIKSolverKukaIIWA, AmbiguityResolver, and ClosedFormIKSolverUR.

pure virtual 
Specifies whether to check joint limits before returning a solution.
check  [in] If true the method should perform a check that joints are within bounds. 
Implemented in ParallelIKSolver, JacobianIKSolver, IKMetaSolver, PieperSolver, CCDSolver, IKQPSolver, ClosedFormIKSolverKukaIIWA, AmbiguityResolver, and ClosedFormIKSolverUR.

pure virtual 
Calculates the inverse kinematics.
Given a desired and the current state, the method solves the inverse kinematics problem.
If the algorithm is able to identify multiple solutions (e.g. elbow up and down) it will return all of these. Before returning a solution, they may be checked to be within the bounds of the configuration space. (See setCheckJointLimits(bool) )
baseTend  [in] Desired base to end transformation 
state  [in] State of the device from which to start the iterations
