This paper describes an extended manipulability measure for robot arm based on bi-articular muscle principle. There are several manipulability measures for serial link manipulator. However they can not be applied for manipulators which has animal-like actuator alignment. Bi-articular muscle is an unique actuator of animals. It connects two joints and drives both simultaneously. Conventional measures...
This paper describes a novel design of robot arm and its experimental verification. The proposed robot arm has a bi-articular driving mechanism. The bi-articular driving mechanism drives both shoulder and elbow joints simultaneously like a bi-articular muscles of animals. The mechanism is built by timing belt and pulleys. The proposed robot arm mimics human upper arm with 3 DC motors working as three...
Motor's fast torque response is one of the advantages of electric vehicles (EVs), and the advanced anti-skid control is included in this advantage. Simulation results show that the feedback gain of wheel velocity control can be high enough to suppress the serious skid, if the actuator delay is small enough. The dynamics of wheel can be changed with this control, and the driven wheel's inertia can...
In this paper, novel multirate two-degree-of-freedom controllers are proposed for digital control systems, where it is restricted that the speed of the A/D converters are slower than that of the D/A converters. The proposed feedforward controller assures the perfect tracking at M inter-sampling points. Moreover, it is shown that the structure of the proposed perfect tracking controller is very simple...
The attempt to realize a "magic carpet"-an array of actuators on which a ball, for example, can be moved to a specified position-driven by autonomous decentralized type control algorithm is proposed. The algorithm is evaluated mainly by computer simulation and trial manufacturing of experimental setup. Due to the recent development of micromachine technology, we can integrate a lot of very...
