Abstract
A location-force target path creator creates a smooth target path function from target values among values of location, position, force and moment given for a force control system. The target values are set as nodes together with times for which the target values are applied. The nodes are projected onto a time axis having a time region which is divided into a series of time regions. A target path function is calculated for an element motion by applying a boundary condition to each of the time regions.
