Gets whatnow? Well Kinematics is the physics or maths of the movement of things. Inverse kinematics is the use of the equations of the movement of things to get the part of a robot to where you want it to go.
Bob Stone and Nick Moriarty of York Hackspace set to first building one of our very first MeArm Robots and then giving it some much needed brains by application of Inverse Kinematics. So that now you can provide a place in space with Cartesian coordinates (x,y,z) and the claw will go there. They've shared the code on Github as they are amazing and also a video on the youtube.
