ArachnoBot Hexapod

68 stars on GitHub.

ArachnoBot is a 3D-printed hexapod spider robot with 18 degrees of freedom — three joints per leg across six legs. Built around a central frame with six symmetrical legs, it uses standard hobby servos for all joints. The project provides complete STL files for every structural component: the frame, central servo holders, side servo holders, coxa links, femur links, tibia tips, claws, electronics plate, controller plate, power compartment, and carapace.

The design is modular — a carapace plate covers the body electronics, the power compartment provides protected battery mounting, and a push-fit stand allows the robot to rest in a stable neutral position. Assembly documentation and BOM are provided in the README.

The design is inspired by the MakeYourPet community hexapod designs by Discord user "amelendez8", who contributed the leg geometry that enables smooth multi-gait locomotion. The original inspiration comes from the MakeYourPet project, adapted and extended for this build.

At 25 unique printable parts covering every leg segment and body panel, this is a complete hexapod kit that teaches hexapod kinematics, servo coordination, and 6-legged gait planning.

This repository is primarily mechanical CAD files (FreeCAD, STL) with minimal software. Servo control code, if any, lives in a separate or forked repository. The orobot Program code is a reference stub only. To run this robot, find the corresponding firmware repo and adapt the serial bridge code in this Program's editor to match the actual command protocol.
