Robot locomotion is the collective name for the various methods that robots use to transport themselves from place to place. Although wheeled robots are typically quite energy efficient and simple to control, other forms of locomotion may be more appropriate for a number of reasons (e.g. traversing rough terrain, moving and interacting in human environments). Furthermore, studying bipedal and insect-like robots may beneficially impact on biomechanics.
A major goal in this field is in developing capabilities for robots to autonomously decide how, when, and where to move. However, coordinating a large number of robot joints for even simple matters, like negotiating stairs, is difficult. Autonomous robot locomotion is a major technological obstacle for many areas of robotics, such as humanoids (like Honda's Asimo).
In terms of energy efficiency on flat surfaces, wheeled robots are the most efficient. This is because an ideal rolling (but not slipping) wheel loses no energy. A wheel rolling at a given velocity needs no input to maintain its motion. This is in contrast to legged robots which suffer an impact with the ground at heelstrike and lose energy as a result.
Scientists have created a robot that can move around just like an insect, powered by a simple circuit capable of generating many complex behaviours. The circuit employs chaos theory the idea that systems are very sensitive to small changes, which can quickly become magnified. The robot, called AMOS, can use its simple circuit to respond to light and sound, pull its foot out of a hole, or run away from obstacles thrown in its path.

Update 14.01.2013: Thank you all for the unexpected positive feedback relating to my work. If you are seriously interested in knowing more about it or building the robot I recommend you to read my newly released book http://dx.doi.org/10.1007/978-3-642-34682-8 which is based on my Master's Thesis. (For building the robot only I suggest to take a closer look at the chapter "Biomimetically Inspired Robot Prototype"). Please comprehend that I cannot support you with this for free since it´s under contract with Springer. For a kind email though, I can support you with the CAD-data and programming-code!

Jonathan Hurst College of Engineering Deans Professor, Oregon State University April 01, 2016 Abstract Legged locomotion is a challenging physical interaction task: underactuation, unexpected impacts, and large and rapidly changing forces and velocities are commonplace. Utilizing passive hardware dynamics in tight integration with the software control, with both aspects of “behavior design” considered together as part of the overall design process, can drastically improve the performance of a machine as measured by efficiency, agility, and robustness to disturbances. This design philosophy was recently demonstrated on ATRIAS, a bipedal spring-mass robot. The passive dynamics of the hardware match a simple biomechanically-derived spring-mass model, while the software control relies on th...
Imagine a world in which robots interact wth us on a daily basis, where seeing a robot walking down the street is no longer the realm of science fiction. This reality is closer than it appears and according to Oregon State University researcher Jonathan Hurst, science fiction will soon become science fact. Jonathan W. Hurst is an Associate Professor of Robotics in the School of Mechanical, Industrial, and Manufacturing Engineering at Oregon State University, as well as the co-founder and Chief Technology Officer of Agility Robotics. He holds a B.S. in mechanical engineering, and both an M.S. and Ph.D. in robotics, all from Carnegie Mellon University. His university research focuses on understanding the fundamental science and engineering best practices for legged locomotion. Investigati...

Google Tech Talks February 28, 2007 ABSTRACT Self-reconfigurable modular robots are metamorphic systems that can autonomously change their logical or physical configurations (such as shapes, sizes, or formations), as well as their locomotion and manipulation, based on the mission and the environment in hand. Because of their modularity, versatility, self-healing ability and low cost reproducibility, such robots provide a flexible approach for achieving complex tasks in unstructured and dynamic environments. They are well suited for applications such as search and rescue, reconnaissance, self-assembly, inspections in hazardous environments, and exploration in space and ocean. The construction and...
*** Hackathon Link: http://bit.ly/2ka4GD9 *** Meetup Link: http://bit.ly/2ka1AiC Modular self-reconfigurable robots involve various modules that can combine themselves autonomously into a structure that is capable of performing a specific task under certain circumstances or performing different locomotion modes. In this webcast, we review numerous self-reconfigurable modular robotic systems along with the challenges, opportunities, and applications for such systems.
The worlds largest technology companies and science funding agencies are investing millions in robotics. They anticipate robots that perform work as first responders, efficiently explore the surfaces of planets, and streamline product manufacturing and delivery. However, despite the existence of incredibly capable hardware, the limitations of our best software for controlling and analyzing complex systems prevents us from unleashing these robots into the wild. In this talk, Kuindersma describes my research on designing optimization algorithms that improve our ability to control dynamically-complex physical robots.
