A hexapod spider robot that can be controlled by OpenCR, CM-700, OpenCM, or an Arduino with Robotis Shield. The robot is motorized by eighteen Robotis Dynamixel AX-18A servos, and has one Robotis AX-S1 integrated sensor mounted on a turret that is motorized by two Robotis Dynamixel AX-18A servos The robot frame is a slightly modified TrossenRobotics ABS PhantomX kit.

SpiderBot VSCode

Overview

This project is a firmware for a hexapod robot ("SpiderBot") using Dynamixel AX-18A servos. The code is designed for Arduino-compatible microcontrollers and provides modular control for legs, a sensor turret, and optional AX-S1 sensor modules.

Features

  • Hexapod Leg Control: Modular support for 6 legs, each with multiple degrees of freedom.
  • Dynamixel Servo Communication: Uses DynamixelWorkbench for robust servo management.
  • Sensor Turret: Pan/tilt turret control for sensors or cameras.
  • RC Controller Support: Remote control via serial interface.
  • Gait Controller: Multiple walking gaits and speed control.
  • AX-S1 Sensor Integration: Read temperature, luminosity, and sound level; control onboard LED.

Getting Started

Prerequisites

  • PlatformIO installed (VS Code recommended)
  • Supported Arduino-compatible board (e.g., Teensy, STM32, ESP32)
  • Dynamixel servos and compatible power supply
  • (Optional) AXS-1 sensor module

Building and Uploading

  1. Clone this repository:

    git clone <your-repo-url>
    cd HexapodPlatformIO
  2. Open the project in VS Code with PlatformIO extension.

  3. Connect your board via USB.

  4. Build and upload the firmware:

    pio run --target upload

Configuration

  • Edit Config.h to set pin assignments, baud rates, and other hardware-specific parameters.

Usage

  • On startup, the robot initializes all modules and prints status messages to the serial monitor.
  • The main loop demonstrates turret movement; you can expand this to add walking, sensor reading, or remote control.

File Descriptions

  • src/main.cpp - Main firmware entry point; initializes all modules and runs the main loop.
  • include/AXS1Sensor.h / src/AXS1Sensor.cpp - Interface for the AX-S1 sensor module.
  • DynamixelController.* - Handles low-level servo communication.
  • Hexapod.*, Leg.* - Implements hexapod kinematics and leg control.
  • Turret.* - Controls the pan/tilt sensor turret.
  • RCController.* - Handles remote control input.
  • GaitController.* - Manages walking gaits and timing.
