Popis: With the growing number of various robots in the world, the task of inverse kinematics still presents interest for researchers. In this paper, we show a group of robots with similar convenient structure, named simplified tree structure (STS), and suggest an approach to find a solution for these robots in a simple way. The approach is demonstrated on the example of a robot with three branches which can form different kinematic loops. An algorithm is also presented that unifies IK solution for a 5-DoF arm of certain structure with usual sufficient 6-DoF arm. Both algorithms are verified on 3-D models in Unity3D engine.
