The purpose of the research is to develop a myriapod robot i-CentiPot ??? that achieves significant mobility against unpredictable environment via passive dynamics. In the paper, we change foot phase, and observe locomotion. We also consider about the analogy between i-CentiPot ??? and some myriapoda.
We have developed a full metal seal compact ion source for the evaluation of the beam transport line. Positive ions of argon have been extracted from a compact full metal seal ion source of 55 mm diameter, 57 mm long inside volume. The argon ion beam current density was reached 0.18 mA/cm2 by changing the discharge current for source operating gas pressure above 6-9x10-9 Torr with 90 V discharge voltage,...
Carbon molecular ions were extracted from an ion source operated with a carbon filament cathode. The mass spectrum of the extracted beam showed a higher current of diatomic carbon molecular ions than atomic carbon ions. The magnetic filter field successfully reduced extraction of smaller mass ions, to make molecular carbon ion current comparable to the ion current of helium, which was used as a discharge...
Positive and negative ion beams are extracted from a plasma sputter type ion source with the planar magnetron sputtering target. A planar copper magnetron target excites plasma by 13.56 MHz RF power. The extraction electrode faces the target with a pair of permanent magnets to reduce arcing for negative ion extraction. Positive and negative ions are extracted from the ion source, and the performance...
A dual microwave antenna plasma source is developed for applications to ion sources and plasma flood guns of ion implanters. The source excites a plasma by 2.45 GHz microwave power along a dual rods microwave antenna coupled to arrays of cusp magnetic fields. Plasma drift associated with the magnetic field gradient enhances the plasma transport along the antenna to homogenize the plasma luminous intensity...
This research effort proposes to use an avalanche beacon to search victims in a disaster field. An avalanche beacon is the device that a mountain climber is equipped with in a snowy situation, which is used to find the climber when he/she is caught in an avalanche. By examining a magnetic field generated by the avalanche beacon, rescuers can search for and approach victims buried under snow. At 457...
AC servo motors are operated by current sensors. However, these current sensors often exhibit offsets caused by age-related deterioration and thermal variation. Gain deviation also causes current measurement errors. These errors lead to torque ripples and dq-axis current ripples. This paper proposes a new method of estimating and compensating for gain deviation in current measurement using a current...
