400元遥操95%机械臂！上海交大推出开源项目U-Arm，打造通用、低成本的人机遥操作接口

Core Viewpoint - Shanghai Jiao Tong University has launched an open-source remote operation project called U-Arm, which can be built for only 400 CNY and is compatible with 95% of mainstream robotic arms [4][3]. Cost Efficiency and System Design - Traditional remote operation systems are often expensive, with systems like the ALOHA project costing over 20,000 USD [2]. - U-Arm offers a low-cost solution that significantly reduces expenses while maintaining efficiency [4][15]. - The hardware design of U-Arm has been optimized to lower costs and improve maintainability and lifespan [14][15]. Compatibility and Usability - U-Arm is designed to work with three main structural configurations of robotic arms, allowing users to easily plug and play by selecting the appropriate hardware for their specific robotic arm type [8][16]. - The system has been validated on various robotic arms, including XArm6, Dobot CR5, and ARX R5 [10]. Performance and Efficiency - In experiments involving five different grasping tasks, U-Arm demonstrated a 39% reduction in average operation time compared to using a game controller [23]. - While U-Arm showed a decrease in success rates for precision tasks like can stacking, the overall efficiency gains in data collection were deemed acceptable trade-offs [24][23]. Data Quality and Natural Motion - U-Arm is capable of producing more natural motion trajectories compared to traditional controllers, which aids in better model convergence during training [25][27]. - The project has made all hardware and software resources available on GitHub, promoting further development and collaboration in the field [27].
