A novel two-dimensional (2-D) linear piezoelectric stepping platform using two parallel longitudinal-bending hybrid actuators is proposed in this paper. The moved the X-direction by combing vertical and horizontal bending motions of actuators, whereas movement V-direction realized longitudinal motions. designed its operating principles orthogonal directions are described. finite-element method simulations performed to verify 2-D platform. Two fabricated a prototype assembled. measured...
Amphibious robots can undertake various tasks in terrestrial and aquatic environments for their superior environmental compatibility. However, the existing amphibious usually utilize multi-locomotion systems with transmission mechanisms, leading to complex bulky structures. Here, a miniature robot based on vibration-driven locomotion mechanism is developed. The has two unique rigid-flexible hybrid modules (RFH-modules), which soft foot flexible fin are arranged rigid leg conduct vibrations...
An inchworm type piezoelectric actuator with four driving feet is proposed and tested. The has merits of easy fabrication miniaturization structure by using a boned-type structure. Horizontal vibration mode vertical are produced synchronously certain temporal phase, their superimposition makes the produce elliptical movements. actuators can achieve bidirectional motion easily exchanging two signals. resonance frequencies modes tuned to be close at 41.35 kHz adjusting structural dimensions....
Some type of penetration into a subsurface is required in planetary sampling. Drilling and coring, due to its efficient penetrating cuttings removal characteristics, has been widely applied previous sampling missions. Given the complicated mechanical properties regolith, suitable drilling parameters should be matched with different formations properly. Otherwise, faults caused by overloads could easily happen. Hence, it necessary establish load model, which able reveal relationships among...
A novel U-shaped piezoelectric ultrasonic motor that mainly focused on miniaturization and high power density was proposed, fabricated, tested in this work. The longitudinal vibrations of the transducers were excited to form elliptical movements driving feet. Finite element method (FEM) used for design analysis. resonance frequencies selected vibration modes tuned be very close each other with modal analysis movement trajectories feet gained transient simulation. mechanical output abilities...
Inspired by a way of rowing, new piezoelectric driving quadruped micro-robot operating in bending-bending hybrid vibration modes was proposed and tested this work. The robot consisted steel base, four connecting pins similar legs, all legs were bonded ceramic plates. principle is discussed, which based on the first order vertical bending horizontal vibrations. motivated foot to form an elliptical trajectory space. vibrations used provide forces for motion. fabricated according principle....
Compared with conventional drill, an ultrasonic drill can break into rocks under lower weight on bit and power, which is more suitable to sample in low gravity environment for deep-space exploration. However, the cannot remove rock cuttings effectively when drilling a certain depth. This paper proposed rotary-percussive (RPUD), depends single piezoelectric transducer produce moment cuttings. The RPUD consists of four parts: piezo-ceramics, percussive unit, rotary tool. Percussive unit...
A novel ultrasonic levitating bearing excited by three piezoelectric transducers is presented in this work. The are circumferentially equispaced a housing, with their center lines going through the rotation of spindle. This noncontact has ability to self-align and carry radical axial loads simultaneously. finite element model built ANSYS, modal analysis harmonious response conducted investigate its characteristics driving parameters. Based on nonlinear acoustic theory thermodynamic ideal...
Drilling and coring, due to their efficient penetrating cutting removal characteristics, have been widely applied planetary sampling returning missions. In most autonomous drilling, there are not enough prior seismic surveys on sites' geological information. Sampling drills may encounter uncertain formations of significant differences in mechanical properties. Additionally, given limited orbital resources, a stuck fault under inappropriate drilling parameters. Hence, it is necessary develop...
