This paper present a framework called the Stack Of Tasks (SoT) implementing a Generalized Inverted Kinematics. This particular implementation provides a run-time graph of computational nodes. It can be modified through a specifically targeted scripting language. It allows hybrid control scheme necessary for complex robot applications such as a HRP-2 humanoid robot in a collaborative working environment. We also show through a case study that this framework allows an efficient integration in nowadays middleware such as CORBA.
