Hi, I want to ask if there is a Forward/Inverse Dynamics Library for a robot model

Thanks in advance for your help!

the recent openrave versions (0.7.x) have inverse dynamics which can be used as :

robot.SetDOFValues(dofvalues)
robot.SetDOFVelocities(dofvelocities)
torques = robot.ComputeInverseDynamics(dofaccelerations)

you can also split the contributions

torqueconfiguration, torquecoriolis, torquegravity = robot.ComputeInverseDynamics(dofaccelerations,None,returncomponents=True)

I suppose you mean forward and inverse kinematics, not dynamics? The easiest option is probably the package arm_kinematics_constraint_aware, although there are other options (such as OpenRAVE's ikfast module).

Thank you, this package seems to be one solution. However, my needs are not only kinematics but also dynamics.
