Walking-robot technology has reached an advanced stage of development, as has already been demonstrated by a number of real applications. However, further improvement is still needed if walking robots are to compete with traditional vehicles. Some potential improvements could be gained through optimization. Thus, this paper presents a method for distributing the legs around the robot's body such as to reduce the forces the legs must exert to support and propel the robot. The method finds

A walking robot has been built to assess the theoretical results. Index Terms -Energy efficiency, legged locomotion, mobile robots, optimization methods. 0-7803-8914-X/05/$20.00 ©2005 IEEE.
