Structure design and motion analysis of bionic hexapod origami robot
A new design scheme of crab-like hexapod origami robot was proposed by combining the origami structure with the multi-legged robot design and coupling Miura origami and six-fold origami aiming at the problems that the existing origami robots have a single structure and insufficient flexibility in movement.The motion configuration of the origami robot was expanded,and the motion flexibility of the origami robot was improved.Each leg of the robot has two degrees of freedom under the symmetry hypothesis.The vertices of the robot legs were treated as joints,and the crease lines were regarded as links.A planar link equivalent model of the robot legs was established with the folding angle as the motion variable.The theoretical range of motion for the robot's foot was determined through simulation calculations.Then tapered panel technique was utilized to thicken the folding surfaces and prevent physical interference between adjacent folding surfaces.A three-dimensional model of the origami crab-like hexapod robot was constructed.The relationship between the folding angle and foot motion was analyzed based on the equivalent model of planar links,and the foot motion trajectory and gait of the robot were designed.The experimental prototype of origami bionic hexapod robot was designed and manufactured by using 3D printing technology,and the lateral movement of the robot was realized based on STM32 microcontroller control.Results show that the origami bio-inspired robot can realize the conversion from plane configuration to a crab-like configuration.The robot can move smoothly left and right under the coordinated movement of six legs.
