The vehicle has a roll axis extending from a front end of the vehicle to a back end of the vehicle.
The slider is mounted so the slider can pivot in a radially oriented roll plane (18) about an effective roll axis (44).
A rotatable platform (22) is mounted within the case and carries an inertia! measurement unit (IMU) (30) and a roll axis gyroscope (34).
The ball-and-socket joint allows relative rotational motion of the T-piece in a pitch axis, a yaw axis, and a roll axis.
One end (128A) of the elongate member (128) is operatively engaged for travel along the inner face so as to rotate the module (105) about a roll axis.
The wing-drive (103) is capable of independent movement about three rotational degrees of movement; movement about a flap axis is independent of movement about a yaw axis, and both are independent of changes in the pitch of the wing (101).
A pivot carriage is mounted on the pivot carriage support bar for rotation about a roll-axis defined by the pivot carriage support bar.
A system for measuring relative angular position about a roll-axis, a yaw-axis, and a pitch-axis includes a source assembly (12) and a receiver assembly (16).
A hip joint (22) is provided which is capable of rotating around a rolling axis (22a1) of a hip joint body (18), and which is capable of rotating around a pitching axis (22a2) of a thigh member (12a).
At least one rotation-rate sensor (DRSx, DRSy) is also provided to measure the angle speed of the vehicle (FZ) in relation to the rolling axis (x) thereof and, possibly, also in relation to the pitching axis thereof.
To achieve this, the first cardanic axis (24) together with the rolling axis (18) form an acute angle (α) and the bearing structure (20) is mounted to rotate about the rolling axis (18).
