An apparatus for performing emulation on a robotic application includes an emulation unit configured to perform emulation on a symbol and function corresponding to a control command of a robotic application. The image files include a plurality of streams such as a control stream, a data stream, a bitmap stream, and a cluster map stream. Accordingly, the processor that, for example, completes a current frame relay is stalled until the other processor has completed its rendering function for a particular odd line, even line, entire frame or partial frame as desired. Depending on the use, the color change agent may be reversible or irreversible. Also, this setup provides a stable configuration since the bicycle is pulling the trailer. The first type and the second type of chips are different from each other in position of the stripe-like waveguide structure with respect to a width direction of each chip and also in area ratio of the electrode pad to the main surface of the substrate.
