Design and working principle of the robot.

Caption

(A) The structure of the robot. (a) The robot includes the piezoelectric ceramics, metal body, power source, and control system. (b) The arrangement and structure of piezoelectric ceramics. (B) Signal distribution, spatial arrangement, and polarization directions of the piezoelectric ceramics (the positive and negative signs only indicate the polarization direction, independent of the electrode). (C) The 4 consecutive key states of the robot in one motion cycle. (D) Generation strategy of the multi-dimensional elliptical vibration trajectory at the foot end. (E) Series of optical images recording the linear motion process of the prototype robot. (F) A photo of the 2 robots’ metal bodies, alongside a 1-dollar coin.
