WebbThe procedure of finding feasible joint configurations and the mathematical problem associated with it are known as inverse kinematics - a core part of motion planning, trajectory optimization, calibration and other important challenges in successfully performing robotic manipulation. WebbThe robot kinematics can be divided into forward kinematics and inverse kinematics. Forward kinematics problem is straightforward and there is no complexity deriving the equations. Henc e, there is always a forward kinemat-ics solution of a manipulator. Inverse ki nematics is a much more difficult prob-lem than forward kinematics.

There are many methods of modelling and solving inverse kinematics problems. The most flexible of these methods typically rely on iterative optimization to seek out an approximate solution, due to the difficulty of inverting the forward kinematics equation and the possibility of an empty solution space. The core idea behind several of these methods is to model the forward kinematics equation using a Taylor series expansion, which can be simpler to invert and solve than the origin… Webb9 jan. 2012 · There are two approaches to solving inverse kinematics: Analytical – requires a lot of trigonometry or matrix algebra Iterative – better if there are lots of links and degrees of freedom.
