Detailed Description

template<typename T = double>
class clockwerk::Frame< T >

Frame class definition.

This file defines the frame class, which is the base of all 6-DOF kinematics and dynamics. This frame class is designed for recursive chaining, and represents the relationship of a frame to its parent.

The frame class tracks the frame's relationship to its parent via the following four key parameters: pos_f_p__p - The position of the child frame relative to its parent, in PARENT coords vel_f_p__p - The velocity of the child frame IN THE PARENT FRAME, in PARENT coords. quat_f_p - The attitude quaternion of the child frame relative to its parent ang_vel_f_p__f - The angular velocity of the child frame relative to its parent, in FRAME coords

Frame relationships to their parents are also defined by the Joint class, which is a method for tracking the degrees of freedom (and thus, which channels can have a nonzero velocity value). Each frame has a translational and rotational joint, which sets degrees of freedom in the velocity (represented in parent coordinates) and angular velocity (represented in frame coordinates). The frame joint is set to fully fixed by default, but can be set to free or modified later.

Frame states may be set by calling the parent relative states directly (they are DataIO objects, but buyer beware that you can set the frame states with almost no restrictions.)

Alternatively, users may get and set frame states relative to the root frame by calling the root relative functions which are provided by this class. The functions rootRelPosition, rootRelVelocity, rootRel... and so on all return the frame state relative to root. The functions setRootRel... will set the frame's state relative to the root frame. For many applications it is better to work with the root functions, rather than parent relative functions.

Naming conventions

The naming convention for all vectors is: variablename_obj1_obj2__frameN (note the double underscore preceding frame) and reads back as: "variable variablename representing the relationship between obj1 and obj2 represented in frameN"
The naming convention for attitude representations is the same as the above, with the trailing frame representation omitted.
The omega vector is sometimes denoted by w and assumed frame consistent with the attitude representation. For example, if a DCM represents the relative orientation between two frames [BN] the omega vector is assumed to be w_(B/N)
The frame represented by this class is denoted with "f" for simplicity
Unless otherwise noted angles and angular rates are in RADIANS
Where relevant and unless otherwise noted, all units are metric
