Fuzzy optimization of foot-trajectory profiles in walking machines

چکیده
Leg dynamics obstructs the trajectory following at high speed, thus being responsible of tracking errors and system instability. The election of trapezoidal or parabolic foot velocity profiles can deal with leg dynamic effects. However, the effects of leg dynamics are different for each foot trajectory. Therefore, to optimize foot speed, the foot velocity profile should adjust to leg dynamics for each trajectory in the whole leg workspace. The herein proposed method for trajectory generation is suitable for achieving accurate, smooth and fast foot movements, increasing leg speed as much as leg dynamics allows for each trajectory.

Using soft computing techniques for improving foot trajectories in walking machines
Walking machines have been investigated during the last 40 years and some basic techniques of this field are already well known. However, some aspects still need to be optimized. For instance, speed seems to be one of the major shortcomings of legged robots; thus, improving leg speed has been chosen as the main aim of this work. Although some algorithms for optimizing trajectory control of robo...
متن کاملPareto design of fuzzy tracking control based on the particle swarm optimization algorithm for a walking robot in the lateral plane on slope
Many researchers have controlled and analyzed biped robots that walk in the sagittal plane. Nevertheless, walking robots require the capability to walk merely laterally, when they are faced with the obstacles such as a wall. In walking robot field, both nonlinearity of the dynamic equations and also having a tracking system cause an effective control has to be utilized to address these problems...
متن کاملA determinant of the leg swing trajectory during walking
When we walk, there are infinite number of possible trajectories for leg swing. How does the brain design the trajectory? As a candidate for the strategy of the trajectory selection, we assessed the criterion of the minimization of the energy cost in this study. We computed the optimal leg trajectory that minimizes the energy cost during the swing phase under the boundary condition that enables...
