Opis:: We found the easy and efficient synthesis method of the vertically aligned ultralong multi-walled nanotubes using iron chloride powder. The 2.1-mm-long bulk nanotubes can be grown by conventional thermal chemical vapor deposition on bare quartz surface with the single gas flow of acetylene for 20 min. In addition to the high growth rate, the bulk of carbon nanotubes is easily spun into the yarn by pulling it out, and the present method also provides the coating ability with nanotubes as a new functionality of this nanomaterial.

Opis:: This paper proposes the usefulness of combining an electromagnetic clutch and brake with a pendulum for antiswing for developing a stabilized wideband pendulum-type gravity direction sensor. The pendulum-type sensor is high in response to direction change but liable to swing even when the change stops, in general. Therefore, anti-swing control without degrading sensitivity of direction measurement is important. Continuous damping of the pendulum motion causes an error in a stationary condition unless the pendulum is free from damping repetitively in an appropriate term. To develop a quick response direction sensor without error, we use a magnetic device. Based on motion analysis of a double pendulum, we simulate behaviours of the pendulum-type sensor by actuating the magnetic device by using different signals in form, frequency and magnitude. Also, we fabricate a motion simulator having two rotation joints to evaluate the anti-swing effect of the magnetic device. In the experiment we demonstrate that the device is beneficial for suppressing pendulum vibration over a wideband for measuring resultant direction of the acceleration compound with motion and gravity on such a platform moving randomly. Also, we show that a triangular signal is better than a sinusoidal signal for making the settling time short; however difference is within a narrow margin.

Tytuł:: Chassis Design of a Mobile Robot for Reducing Weight by Excluding Suspension Elements
Autorzy:: Okada, T.
Mimura, N.

Powiązania:: https://bibliotekanauki.pl/articles/385173.pdf

Tematy:: mobile robot

Opis:: This paper proposes the design concept that prevents its total weight from increasing. The object of the methodology is to modify a conventional robot chassis for structural simplicity by composing the chassis from an elastic material so that it can reduce vibration and shock to the body. This idea makes it unnecessary to attach additional elements, such as suspension units; in addition, it means that it is possible to easily deform the chassis by forming long holes, and to decrease the total weight of the robot, even when the chassis is thick enough for functionality. It contributes to preventing the weight of the power source from increasing. Structural models for analyzing flexure of the chassis using the finite element method (FEM) are pursued. Also, dynamic behaviors of the chassis are clarified based on the modal analysis. The minor difference in error between the experimental and analytical data verifies that the models are useful in a practical application.
