The invention discloses a rigidity-variable bionic robot foot based on a low-melting-point alloy. The invention relates to the technical field of robots. The bottom of a bionic robot shank is rotatably arranged in the middle of a bionic robot foot bottom through a first connecting shaft, and two connecting columns are rotatably arranged on the two sides of the middle of the bionic robot shank through second connecting shafts; the two variable elastic assemblies are rotatably arranged at the rear end of the foot bottom of the bionic robot through third connecting shafts; the variable elastic assembly comprises a base, a low-melting-point alloy variable rigidity layer, an elastic piece, a top plate and at least two guide columns. According to the invention, simulation work of human ankle and foot joints can be effectively realized, and good cushioning and supporting effects are provided for walking and movement of the robot. Wherein the elastic coefficient of the variable elastic component can be adjusted in real time by controlling the temperature of the low-melting-point alloy variable rigidity layer, so that the requirements under different working conditions are met.

    本发明公开了一种基于低熔点合金的可变刚度仿生机器人脚。本发明涉及机器人技术领域。本发明的仿生机器人小腿的底部通过第一连接轴可转动的设置在仿生机器人足底的中部,两个连接柱通过第二连接轴可转动的设置在仿生机器人小腿的中部两侧,两个可变弹性组件通过第三连接轴可转动的设置在仿生机器人足底的后端;可变弹性组件包括底座、低熔点合金可变刚度层、弹性件、顶板、至少两个导向柱。本发明可以有效实现对人类踝足关节的模仿工作,为机器人行走与运动提供良好的缓震与支撑作用。其中,通过控制低熔点合金可变刚度层的温度,可以实现对可变弹性组件的弹性系数进行实时调节,从而满足不同工作条件下的需求。
