    Prefix
    Using the theory of forced vibration of continua, especially bending vibration of beams and plates, it is possible to create systems which are small, light and cheap with a relative simple design. Following the principle «intelligence in the mechanics»
    Exact

    Suffix
    robots are in the design process (figure 1), which are controllable by only one actuator to perform motion in three degrees of freedom. In the following figures four mobile robots for 2-dimensional locomotion on a flat surface are presented.

    Suffix
    – autonomous, programmable and remote controlled robot driven by a single piezo actuator using resonance characteristics of elastic continua Design issues In choosing the right actuator the most critical issue to consider is the speed to excite the resonance characteristics of small mechanical devices.

    [4]
    Suffix
    . The main disadvantages of SMA and IPMC are the slow speed, the small force and the relative high power consumption. By consuming a large amount of energy DC motors have the possibility to create a very large displacement with a high speed and a moderate force.
