The invention provides a bionic obstacle crossing robot driven by an electric response material. The bionic obstacle crossing robot comprises a first driver, a second driver, a multi-section type elastic framework, a foot support, a sole buffer layer structure and a polymer fastener. The multi-section type elastic framework comprises a front-section framework and a rear-section framework; the first driver is mounted on the front-section framework, and a hollow structure is arranged on the rear-section framework; the second driver is mounted on the hollow structure; the foot support is installed on the rear-section framework, and a sole buffer layer structure is installed on the foot support. The first drivers are shape memory alloy springs, every two shape memory alloy springs form a group and are symmetrically distributed on the upper side and the lower side of the front-section framework, the interval between the fixed positions of the two ends of each spring is larger than the length of the spring in the natural state, and the two ends of each spring are connected to the positive electrode and the negative electrode of an external power source through external wires respectively. The structure that the front section framework is matched with the shape memory alloy spring is adopted, controllable energy storage and release can be achieved, and jumping obstacle crossing movement of the robot is achieved.

    本发明提供了一种电响应材料驱动的仿生越障机器人包括第一驱动器、第二驱动器、多段式弹性骨架、足部支架、足底缓冲层结构以及聚合物紧固件;多段式弹性骨架包括前段骨架与后段骨架;第一驱动器安装在前段骨架上,后段骨架上置有镂空结构;第二驱动器安装在镂空结构上;足部支架安装在后段骨架上,且足部支架上安装有足底缓冲层结构。第一驱动器为形状记忆合金弹簧,形状记忆合金弹簧两个一组对称分布于前段骨架的上下两侧,弹簧两端固定位置的间隔大于弹簧自然状态下的长度,每个弹簧两端通过外接导线分别连接于外置电源的正负极。本发明采用前段骨架与形状记忆合金弹簧相配合的结构,能够实现可控的能量储存与释放,实现机器人的跳跃越障运动。
