Robot4 (tm) is a Robotic Arm Movement program where the arm is moved from a given position to a desired position. The program finds the angles necessary for the desired position. Problem came from NASA. Robot4 is an Inverse Problem example. It wants to solve how to move from starting point `A` to target point `B`. Solutions to Inverse Problems are easy with the Fortran Calculus programming language. See `Rob4User.fc` file.
