Why did you make it?DolphinArm: Desktop Robotic Arm with Unity Real-time Simulation & ESP32 Control

Overview DolphinArm is a high-performance, 3D-printable robotic arm designed for makers, students, and developers. This project bridges the gap between hardware and software by providing a seamless Digital Twin experience. Control your physical arm in real-time using a custom-built Unity interface, powered by the versatile ESP32 microcontroller.

Key Features Unity Real-time Simulation: Features a dedicated Unity project that acts as a digital twin. Move the arm in the virtual environment, and the physical DolphinArm follows with low latency.

Wireless ESP32 Control: Built on the ESP32 platform, supporting both WiFi and Serial communication for tether-free operation.

Precision 3D Design: Optimized for desktop 3D printers. The structure is designed for durability and ease of assembly, compatible with materials like PETG or Carbon Fiber Nylon.

Interactive UI: A sleek Unity-based control panel allows for manual joint control and coordinate input.

What’s Included in This Package? 3D Models (STL Files): Complete set of high-quality STL files for all structural components.

ESP32 Firmware: Well-documented C++/Arduino source code for motor control and networking.

Unity Project: The full Unity source files for real-time simulation and the control interface.

BOM (Bill of Materials): A detailed list of required hardware, including servos, ESP32 boards, and fasteners.

Setup Guide: Step-by-step instructions to get your hardware and software synced up.

Technical Specs Controller: ESP32

Development Environment: Unity (C#) & Arduino IDE (C++)

Communication: WiFi / Serial

Degrees of Freedom (DoF):3-DoF
