    Visual differences with ROBOTIS OP


    Besides color it is almost impossible to differentiate between both robot types

    The only difference is the mini HDMI port connector from ROBOTIS OP2. Also, the location of the ports differ from ROBOTIS OP2 with respect to ROBOTIS OP. The Mode, Start and Reset buttons remain unchanged. ROBOTIS OP2 lacks the 3.5mm microphone and audio jacks. In practice these were not implemented with ROBOTIS OP so the losso of these ports from ROBOTIS OP2 will not affect robot operations.

    Differences 2

    Without careful close inspection it is difficult to tell the difference between both robots
