Introduction

Welcome to the TarsX build log. This comprehensive guide will walk you through every aspect of building your own TARS replica, from initial planning to final assembly.

TarsX is designed to be modular and accessible. Whether you're an experienced robotics engineer or a curious beginner, this project is structured to accommodate different skill levels. Each section builds upon the previous one, creating a logical progression from concept to completion.

The project is divided into several key phases:

  • Design & Planning: Understanding the requirements and creating detailed specifications
  • Mechanical Design: Creating the physical structure and movement systems
  • Electronics Integration: Wiring, sensors, and control systems
  • Software Development: Programming behaviors, AI, and user interfaces
  • Testing & Refinement: Iterative improvement based on real-world testing

This build log serves as both documentation and a learning resource. Feel free to adapt, modify, and improve upon these designs. Innovation happens when we build on each other's work.

Mechanical Observations

One of the most fascinating aspects of TARS is its unique mechanical design. Unlike traditional humanoid robots, TARS uses a modular block system that allows for incredible flexibility and stability.

Key Mechanical Features

  • Modular Block Design: Each segment can move independently, allowing for complex configurations
  • Wide Base Stability: The rectangular base provides excellent stability for various positions
  • Precision Joints: High-torque servos enable smooth, controlled movements
  • Weight Distribution: Careful placement of components ensures balance in all configurations

Movement Capabilities

TarsX can achieve several key movements inspired by the original TARS:

  • Standing upright in a rectangular configuration
  • Folding into a compact form for storage
  • Reconfiguring segments for different tasks
  • Stable movement across various terrains

Early prototypes revealed that the mechanical design needed to balance between flexibility and structural integrity. Too much flexibility meant instability, while too much rigidity limited movement capabilities. The final design represents an optimal compromise.

Custom Parts

Many components of TarsX require custom fabrication. This section details the custom parts needed and how to create them.

3D Printed Components

  • Segment Blocks: Main structural elements, printed in PETG or ABS for durability
  • Joint Housings: Custom enclosures for servo motors and linkages
  • Mounting Brackets: Secure attachment points for electronics and sensors
  • Cable Management: Channels and guides for clean wire routing
  • Display Frames: Custom frames for LED displays and status indicators

Machined Components

  • Aluminum Frame: Main structural frame for rigidity and weight reduction
  • Precision Shafts: For smooth rotational movements
  • Custom Brackets: Metal brackets for high-stress connection points

Electronics Enclosures

Custom enclosures protect sensitive electronics while maintaining accessibility for maintenance and upgrades. These are designed with ventilation, cable routing, and modularity in mind.

All CAD files and 3D printing instructions are available in the project repository, allowing you to manufacture these parts yourself or through a service.

Code

The software architecture of TarsX is built on a modular foundation, allowing for easy expansion and customization.

Core Systems

  • Motion Control: Precise control of all servos and motors for smooth movements
  • Sensor Integration: Processing data from various sensors for environmental awareness
  • AI Behavior Engine: Decision-making system for autonomous behaviors
  • Communication Layer: Interface for remote control and monitoring
  • User Interface: Display management and status reporting

Programming Languages

  • Python: Main control system and high-level logic
  • C++: Performance-critical components and real-time control
  • Arduino: Low-level motor control and sensor reading

Key Features

  • Modular code structure for easy maintenance
  • Comprehensive error handling and recovery
  • Extensive logging for debugging
  • Plugin architecture for custom behaviors
  • RESTful API for external integration

The codebase is open-source and available on GitHub. Contributions, bug reports, and feature requests are always welcome. Documentation is continuously updated to help new developers get started quickly.
