Figure 7 Mean and standard deviations of peak and average negative free moments for the right leg during the rotational movement
for different footwear conditions.
The aim of our study was to develop a device (the NIGHT-Recorder) that can capture axial rotational movements
This means that, at any position, the moving platform linking together all the arms of the microrobot can be treated as a spherical joint .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.
The second part of model consists of 4 sets of equations describing the robot dynamics: Equations for rotational movement
, equations for translation movement, equations for transformation angular and translation speeds between frames, and equations for transformation gravity force to robot axis components.
A torn ligament in the left knee was imminent, caused by the huge rotational movement
of his body while swinging the club.
The rotational movement
and motorised elevation of the double table, with a height range from 72cm to 92cm, is specially designed for wheelchair patients.
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.
