Free Gaits for Quadruped Robots over Irregular Terrain

Joaquin Estremera, Pablo Gonzalez de Santos
2002 The international journal of robotics research  
This article addresses the design, implementation and experimentation of gaits to negotiate uneven terrain with a real machine. The gaits presented are a mixture of free and discontinuous gaits.  ...  The fusion of these two main gaits plus the addition of extra constraints to avoid leg-transfer deadlocking produced a new free-crab gait, a free-spinning gait and a free-turning gait.  ...  This work was motivated by the urgent need to navigate over irregular terrain with a real four-legged robot.  ...
