This means that, at any position, the moving platform linking together all the arms of the microrobot can be treated as a spherical joint [7].Considering technical aspects of presented construction, it should be noted that this situation exists only if no rotational movement is made, which means only when the main axis of moving platform is perpendicular to the base.
The operation in terrestrial mode requires translational and rotational movement of the upper half of the QHA against the lower half and a tilt of 90[degrees].
In short, it results, because of the appearance and the upholding of an atmosphere, in a gaseous mass animated by a rotational movement, that the surface must be delayed relative to the internal mass, in such a way that the superficial currents act only in the direction of the parallels save a slightly marked tendency toward the poles; and that this superficial delay must go increasing from the equator to the poles following a certain law that would be impossible to assign ahead of time, but of which we know this, that the direction of the rotational axis must not be substantially altered.
Delpi, (2001), showed that the cervical extensor muscles exert a force of 52 [+ or -] 11Nm for male subjects and 21 [+ or -] 12Nm for female subjects, the cervical musculature required making the movement of flexion exert a force of 30 [+ or -] 5Nm for male subjects and 15 [+ or -] 4Nm for female subjects, the muscles necessary to carry out cervical lateral flexion movement exert a force of 36 [+ or -] 8Nm for male subjects and 16 [+ or -] 8Nm for female subjects and cervical muscles necessary to carry out lateral rotational movement exert a force of 15 [+ or -] 4Nm for male subjects and 6 [+ or -] 3Nm for female subjects.

While conventional reciprocating compressors turn the motor's rotational movement into the piston's linear movement to compress refrigerant, in LG's linear compressors, the motor directly connected to the piston moves along a linear track to compress refrigerant, minimizing energy loss during conversion and lowering energy use by up to 30 percent.
