A robotic cell enables a robotic station to be downsized and both high maintainability and high rigidity to be attained. To this end, the robotic cell for assembling parts by using multiple robots includes multiple booths for housing multiple trestles, on each of which a pair of robotic arms are mounted, with the trestles adjoining one another. Each trestle has an opening portion on one side surface thereof, through which a power controller box is carried in and out. To compensate for a decrease in rigidity of the trestle due to the opening portion, a connecting member is used for coupling two trestles adjacent to each other across the respective booths. Both end portions of each connecting member are fastened to the both trestles with screws, respectively.
