A biomimetic starfish robot

This invention discloses a biomimetic starfish robot, relating to the field of simulation robots. The biomimetic starfish robot includes a biomimetic exoskeleton, which is obtained by folding a flat plate structure with creases; a shape memory alloy, which is disposed on the biomimetic exoskeleton and drives the biomimetic exoskeleton to deform through its own deformation; and a driving unit for driving the shape memory alloy to deform. The biomimetic starfish robot proposed in this invention uses an electric heating system attached around the shape memory alloy, which can transfer heat to the surrounding environment in a short time. Because the shape memory alloy at the arm-foot junction has a small volume and a low temperature of the austenite phase, the circuit system only needs a relatively weak electrical signal to generate enough heat to deform the shape memory alloy. Therefore, this invention will greatly reduce power consumption, reduce noise pollution, and simplify the design of the circuit system.

This utility model provides a hollow, one-time injection-molded composite fencing, relating to the field of fencing technology. It includes a fencing body and two sound-absorbing components, both fixedly installed on the exterior of the fencing body, for quickly absorbing noise generated during construction.

The remaining sound waves enter the cavity through the sound inlet holes and undergo multiple reflections under the action of a specially designed corrugated plate, significantly extending the propagation path and converting most of the sound energy into heat energy. Finally, the residual sound waves are completely absorbed by the sound-absorbing cotton and the inner wall sound-absorbing panel, achieving noise reduction across the entire frequency band. The structure adopts a multi-layer composite noise reduction design, achieving efficient sound energy absorption through a stepped noise reduction mechanism. This not only effectively reduces noise pollution and harms residents' health but also significantly improves the traffic environment and reduces the risk of accidents caused by noise interference for drivers.
