Abstract
Recently, collaborative simulation environment is needed in the mechatoronics product design. In this research, a systematic collaborative simulation environment is proposed using HLA (High Level Architecture) which is the IEEE standard of a distributed simulation. In this report, an omni-directional electric wheelchair is joined to a federation as one federate, and the verification of acceleration control system is done. SILS (Software-in-the-loop) and HILS (Hardware-in-the-loop Simulation) using HLA can shorten the time until preparing the simulation and obtain more accurate simulation results.
