 ## General Idea.
 So if we want to draw a box. 4 setpoints for each corner should be sufficient.
 This is a simple model detail. We just take the four setpoint and give the system some time to get there.

+## Results
+The implementation was fairly simple, The arm just does a joint move to the next setpoint.
+The control of the motor is still a bit yanky. 
+The next step is probably a better implementation of the motors.
