MEVIUS2: Practical Open-Source Quadruped Robot with Sheet Metal Welding and Multimodal Perception
arXiv · 2603.22031
The Takeaway
By utilizing sheet metal welding instead of 3D printing, it creates a durable, large-scale robot capable of real-world rough terrain. This democratizes the development of high-utility quadruped hardware previously restricted to expensive proprietary platforms.
From the abstract
Various quadruped robots have been developed to date, and thanks to reinforcement learning, they are now capable of traversing diverse types of rough terrain. In parallel, there is a growing trend of releasing these robot designs as open-source, enabling researchers to freely build and modify robots themselves. However, most existing open-source quadruped robots have been designed with 3D printing in mind, resulting in structurally fragile systems that do not scale well in size, leading to the c
