RhinoV2.0 Adaptive Gripper

RhinoV2.0 physical prototype

(opens in a new tab) (opens in a new tab)

📖 Project Introduction

RhinoV2.0 is an open-source adaptive two-finger gripper inspired by the Robotiq 2F-85 commercial gripper. This project aims to provide a low-cost, high-performance, easy-to-manufacture, and easy-to-assemble mechanical gripper solution, enabling more robot enthusiasts, students, and individual developers to access affordable end-effectors.

💰 Cost Advantage: Made using 3D printing, the entire set costs no more than ¥1000, significantly lower than commercial grippers!

🎯 Project Purpose

Lower the Barrier: Commercial grippers are expensive (e.g., Robotiq 2F-85 costs around ¥14,000+), and we aim to make them more accessible to everyone.
Open Source Sharing: All design files are fully open source, supporting free modification and optimization.
Educational Value: Provides design examples for students in mechanical engineering and robotics for learning and reference.
Manufacturability: Uses standard parts and common processing techniques to reduce manufacturing costs.
Scalability: Modular design facilitates secondary development and improvements.

✨ Main Features

💰 Ultra-low cost: The entire set costs < ¥1000 for the 3D-printed version
Adaptive gripping, compatible with objects of various shapes and sizes
Underactuated mechanism design, compact structure
Powered by joint motors (Dynamixel DM4310)
Supports FDM 3D printing or CNC machining
Complete SolidWorks source files and STEP universal format

⚙️ Hardware Configuration

Item	Parameter
Drive Motor	Dmio DM4310 Joint Motor
Grip Stroke	(To be added)
Maximum Grip Force	(To be added)
Weight	(To be added)
Manufacturing Method	FDM 3D Printing / CNC / Sheet Metal

🚀 Quick Start

1. 📄 Obtain the design files

SolidWorks users: Modify the source files directly in 0_Solidworks2025/
Other CAD software: Import the 1_STEP/RhinoV2.0_Assembly.STEP file
