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 Al–Zn–Mg–Cu alloy and an Al–Zn–Mg–Cu–Sc–Zr are used to study effects of co-addition minor Sc Zr on aging precipitates mechanical properties alloys. After solid solution treatment, almost complete recrystallization occurs in the alloy, while is significantly inhibited Al–Zn–Mg–Cu-Sc-Zr with a fraction 12.6%. The has remarkably higher strength than solution-treated water-quenched state, which due Orwan strengthening coherent Al3(Sc, Zr) particles grain boundary for finer grains. At...
For miniature piezoelectric robots, it is difficult to realize multi-degree-of-freedom motion with a simple structure. In this article, novel ring-shaped tripodal robot (RTPR) proposed solve the above difficulty. Multiple modes, based on propagation of mechanical waves rigid structure, are designed continuous/step linear and in-situ rotational motions. The prototype fabricated weight 2.2 g size 20 mm × 4.6 mm, performance tested. test results show that RTPR can achieve maximum speed 39.3...
Isothermal hot compression tests of Al–Mg–Si–Ce–B alloy at 623–823 K with strain rates 0.01–50 s−1 were carried out on a Gleeble 3500 thermal simulation tester. The flow behavior the during deformation was analyzed based true stress–strain curves. Arrhenius equations Zener-Hollomon (Z) parameter and processing maps under conditions various strains constructed. It is proved that prone to plastic instability relatively low temperature, optimized parameters 783–823 K/0.03–0.04 s−1. In addition,...
The changes of stress level for the ultra-high strength Al-Zn-Mg-Cu-Zr alloy were described by constitutive equation with considering lattice diffusion aluminum, zinc, magnesium and copper. Zener–Hollomon (Z) parameter expression based on was used to reflect microstructure. critical σc initiation dynamic recrystallization (DRX) introduced calculate Z parameter. Steady-state dislocation density ρsat ρc DRX decreased increase deformation temperature. dependence activation energy Q temperature...
Abstract A novel miniature biped piezoelectric robot (MBPR) was designed with a patch-type beam structure. The utilizes an asymmetric friction-inertial driving principle to realize linear motion. prominent feature is that it can move linearly under low frequency and voltage, which beneficial for untethered of the robot. In addition, has advantages simple structure, convenience multi-degree-of-freedom extension strong load capacity. effect different dimensional parameters on motion MBPR...
To study the application performances of new aluminum alloy conductors, dynamic mechanical analysis and microstructure observation were used to characterize heat resistance internal friction. Severe recrystallization occurred in Al Al–0.2Ce above 320 °C. The hardness electrical conductivity decreased from 40.3 22.2 HV 61.58 60.87 %IACS after temperature scanning 50 500 °C, which was mainly attributed enhancement electron scattering by recrystallized grain boundaries. co-addition Sc Y element...
