ow that we have fully assembled our
four-link robotic arm and have written
some joystick code that can be used to
control our arm, it’s time to calculate the
inverse kinematics of our system. This will
allow us to input anywhere on our base-
plate grid that we’d like the end effector of
the robotic arm to point to and to calculate
the angles of the two actuators we need
to get there. But more importantly, it will
allow us to write code that will enable us
to use the joystick to increase or decrease
both our x and y targets, giving us much
more control over the system as a whole.
