X-RHex
The X-RHex Robot with rail-mounted handles, November 2010

X-RHex


X-RHex is the latest version of the highly mobile RHex platform, designed with greater strength, longer runtime, and more mobility than previous versions, with a modular payload architecture to support a variety of research needs.

With new levels of mobility and durability, and the capability for rapid behavior development with a modular payload system, X-RHex is an effective research machine both in the laboratory and in outdoor field tests. Six powerful motors actuate compliant legs, allowing X-RHex to traverse a wide variety of terrains, including asphalt, grass, sand, mud, and rocks. By using a mil-spec rail mounted interface and standard electrical connections, X-RHex can support a wide variety of payloads, making it a mobile “laboratory on legs”. Now adding an extra sensor or testing a new behavioral algorithm is as easy as on a bench in the lab.


Key Features

X-RHex is designed to offer substantial improvements over its predecessors in terms of power, run-time, payload size, durability, and terrain negotiation, with a smaller volume and a comparable footprint and weight. Along with these advances, X-RHex incorporates a new modular payload interface and a redesigned electronics architecture. Read on …

Laboratory on Legs

Legged locomotion provides valuable challenges both in terms of the sensing and control required by a mobile robot. X-RHex, as part of a challenge to incorporate sensing onto highly dynamic and mobile legged robots, defines a payload interface to mount a variety of payloads and sensors. The payload system can even carry a second computer with a programmable GPU, making X-RHex the first robot of itís size to have such a computational capability.Read on …

Media Gallery

X-RHex has been shown to be reliable and durable enough to support extensive testing in rough terrains, such as in the rough hills of the Mojave Desert. A collection of photos and videos of the machine in operation are available on this page. Read on …
