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.
