A Mathematical Introduction to Robotic Manipulation - yszheda/wiki GitHub Wiki
- screw motion: a rigid body can be moved from any one position to any other by a movement consisting of rotation about a straight line followed by translation parallel to that line.
- twist
- wrench: Poinsot is credited with the discovery that any system of forces acting on a rigid body can be replaced by a single force applied along a line, combined with a torque about that same line.
- pitch of the screw: the ratio of translation to rotation

Relationship with Denavit-Hartenberg parameters
The workspace of a manipulator is defined as the set of all end-effector configurations which can be reached by some choice of joint angles.
- complete workspace
- reachable workspace (the set of positions (in R3) which can be reached by some choice of joint angles.)
- dextrous workspace
- smooth map
- diffeomorphism & diffeomorphic
- manifold of dimension n
- local coordinate charts
- smooth atlas & smooth manifold
- derivation
- tangent space & tangent vectors
- tangent map
- tangent bundle
