低成本3D打印机械臂，让机器人教育更普及
TARA: A Low-Cost 3D-Printed Robotic Arm for Accessible Robotics Education
- 用200美元成本实现可3D打印的开源机械臂
- 实测在基础操作任务中表现准确
- 适合教学复现与学生动手实践
高昂的机器人平台成本限制了学生获取实际应用技能的机会。为解决这一问题，本文提出TARA——一款低成本、3D打印的机器人机械臂，专为可及的机器人教育设计。TARA提供开源代码库，包含设计文件、组装指南和基础代码，支持用户自行搭建与定制。系统在约200美元的成本下实现了较高功能性能，远低于动辄数千美元的工业级系统。实验验证其在基础操作任务中具备良好准确性。本工作不追求性能指标对比，而是强调教育可复现性，为师生提供一个可稳定复制与拓展的实践平台。
原文摘要 · Abstract (English)
The high cost of robotic platforms limits students' ability to gain practical skills directly applicable in real-world scenarios. To address this challenge, this paper presents TARA, a low-cost, 3D-printed robotic arm designed for accessible robotics education. TARA includes an open-source repository with design files, assembly instructions, and baseline code, enabling users to build and customize the platform. The system balances affordability and functionality, offering a highly capable robotic arm for approximately 200 USD, significantly lower than industrial systems that often cost thousands of dollars. Experimental validation confirmed accurate performance in basic manipulation tasks. Rather than focusing on performance benchmarking, this work prioritizes educational reproducibility, providing a platform that students and educators can reliably replicate and extend.
