Any rotation composed by a generic number of elemental rotations is always referred to a Euler axis and angle. This is the building block of attitude kinematics, since if we “sum” several rotations, we end up with a final axis and angle representing the whole chain. However, this can be...
1 The shear strain is defined as the tangent of the change in angle between the sides of the element ϕ. Then, for elastic material, there exists: F = G tan ϕ, where G denotes the shear modulus. Sign in to download full-size image Sign in to download full-size image 4.4. ...
G68.2 - B axis rotation doesn't match output euler angles When doing 3+2 positioning, the B axis has a defined angle/preference per the below: var bAxis = createAxis({coordinate:1, table:true, axis:[0, 1, 0], cyclic:false, range:[0 - 0.0001, 110 + 0.0001], ...
C# code Example of converting RPY/Euler angles to Rotation Vector/Angle Axis for Universal-Robots. Here’s my C# implementation based on Erwin’s math. I noticed you have to change the theta value depending on the sign...
