Zero-Moment Point (ZMP) is the most popular concept that is applied to stabilize the gait motion of a biped robot. However, the computation of the ZMP position and the dynamic model is highly complex, and so requires a considerable time. Therefore, to eliminate complex computation, this work designs a new locomotion control system for humanoid robots, which yields walking gait characteristics that...
Linear motion carriage with opposing air bearings arrangement for achieving preload force is the target of the study. Such arrangement for preloading the air bearings requires high degree of parallelism between the two opposing bearing surfaces. By introducing a compliant mechanism behind each of the air bearing pads at one bearing surfaces, the parallelism requirements as well as the flatness of...
Precision positioning machines are required to run with higher speed and higher accuracy. The high running speed can cause strong excitations on the machine structure, which results in severe structure vibration and long settling time. This paper presents a low-vibration motion profile generation method to reduce the residual vibration. The acceleration profile is designed by using a level-shifted...
In precision motion stages, jerk limitation is important to suppress transient vibration and to reduce the settling time, as well as to improve the machine speed and accuracy. In this paper, a novel motion control method is presented which aims to reduce jerk and transient vibration for linear motion stages. In this approach, the acceleration profile is designed based on a level-shifted cosinoidal...
