The paper presents a visual application interface for modelling the inverse kinematics of a robot leg as part of a visual intelligent platform for virtual environment robotic simulation. The tracking reference for the angular joints is given using a trained neuro-fuzzy model instead of the usual inverse kinematic system. The validity of the model is checked in the Cartesian workspace. The visual application...
