IEEE Abstract— Impedance control is a well-established framework The usual minimal representation of orientation is given to manage the interaction of the end effector of a robot manip- by a set of three Euler angles which, together with the three ulator with the environment. For the execution...
The exponential map The angle-axis representation The angular velocityThese three concepts are all closely related, so to make sure we're all on the same page, this is exactly how I'm defining them:The exponential map: A specific function which takes a 3D vector and produces a rotation ...

This submission is based on this original implementation on Stack Exchange:https://mathematica.stackexchange.com/a/136500. AxisAngle uses the "Pixar method" to generate the orthogonal vectors needed to apply the Euler fixed point theorem for computing the axis-angle representation....
Given the Direction Cosine Matrix, I want obtain the rotation vector, i.e. the Euler axis/angle? This transformation is common in multi-body dynamics, but I cannot find this same functionality in either the Aerospace Blockset or the Aerospace Toolbox....
Gets the absolute angular acceleration of the device in an axis-angle representation in units of radians per second squared. This acceleration is expressed in the supplied coordinate system, although the motion is measured relative to the user's surroundings. C# Copy public Vector3 Absol...
I have put a java applet here which allows the values to be entered and the converted values shown along with a graphical representation of the orientation. Also further examples in 90 degree steps here EuclideanSpace home Link here for an Axis-Angle to Matrix Calculator. page Prerequisites De...

Grain boundary misorientations are also sometimes displayed in a cylindrical angle/axis space where the base of the cylinder is a stereographic projection for representation of the misorientation axis and the long axis of the cylinder is parallel to the misorientation angle. The space is usually redu...
