Forward kinematics

Forward kinematics is a way to figure out where something will be in space (like location) when it moves. It follows a simple pattern: you first need the angles and lengths of all the pieces (like legs or arms), and then you can calculate a position for the end of the pieces. For example, if you had a robot with two legs, each with a length of 20 cm, you could use forward kinematics to figure out where the robot's feet would be when the legs were angled straight down.
