This paper shows that redundant actuation can reduce the energy consumption of parallel mechanisms, in some cases by a considerable margin. A theoretical analysis for the energy-saving mechanism is elucidated, and an energy consumption model for a servo-motor system is proposed. Our hypothesis is experimentally verified with a widely used two degree of freedom parallel mechanism design driven by three...
This paper presents a new mobile robotic platform (R-Mo) which can reduce unexpected variations in height as well as pitch angle of its main body while traversing rough terrains. As a measure for the smooth movement of mobile platform, the variations in height and pitch angle are chosen in this study. Then, the kinematic analysis on the Rocker-Bogie mechanism is carried out to investigate its variations...
This paper presents a temperature measurement system without the input buffer. A voltage follower or a buffer is required to minimize the influence of the ADC input impedance in the thermistor temperature measurement system. A high performance operational amplifier is usually required to prevent the noise and distortion due to the additional circuit. Negative power is also necessary to prevent the...
This paper presents the controller synthesis for a fine actuation system of a 3-DOF micro parallel positioning platform. The platform is composed of a dual stage servo system for realizing both long stroke and high precision, simultaneously. Among the dual stage, the fine actuation system is more important as it guarantees high speed and accuracy. First, a physics-based model for the fine actuation...
