Description
Summary:This paper presents the design, fabrication and operation of a hexapod fabricated using a combination of printing and folding flat sheets of polyester. The polyester sheets are cut and engraved with crease patterns, which are then manually folded to create 3D functional modules, inspired by the Japanese art of Origami. These modules, when connected, form a hexapod with two degrees of freedom per leg. All custom mechanical parts are manufactured in a planar fashion using a laser cutter. We created this print-and-fold hexapod as a miniature version of a commercially available platform, to which we compare several metrics, such as weight, walking speed, and cost of transportation. Our print-and-fold hexapod has a mass of 195 g, can walk at speeds of up to 38.1 cm/sec (two body lengths per second), and can be manufactured and assembled from scratch by a single person in approximately seven hours. Experimental results of gait control and trajectory tracking are provided.
