Starfox 64 Boss Battle
In the Starfox 64 Boss Battle, you control a small spherical ship while a robot tries to grab at you with his arms. Press enter to activate the robot. The robot will then attempt to grab at the sphere with both arms as you move sphere around using w a s d.
For the movement of the arms, I used Google's Ceres Solver to determine how to set the angles of each link in the hierarchical arm structure in order for the robot to reach for the sphere.
