The paradigm of 21st century is clearly different from 20th century. This is shift from mass production based on standardization to small number and wide variety of production. To take the paradigm shift, any production system should have force control providing high adaptability inside. This gives the difficulty to the motion controller where the position control with very high stiffness and the force control with zero stiffness exist at the same time. This paper introduces a solution using coordinate transformation which connects velocity source and force source in the functional space. The simplest case is the function of transmittal of force between slave and master. This is known as the acceleration-based bilateral control in real world haptics. If such functions will be installed, the production system will have more direct and convenient teaching system. Some examples will be introduced.
