karel move about problem

[MaynardJK]

I am writing a karel program for a FANUC M-16iL robot with a RJ-3 controller. My problem is with aligning the approach vector of the tool with a given vector.

I am getting the angle from the dot product of the two vectors and the "about" vector from the cross product.

After executing the MOVE ABOUT command, the robot is over-rotating by 10-15 degrees. I have checked the math and it is correct. Has anyone else had a similar problem?

I have had that problem many times. Re-check your math.
You should simplify your approach to solving this problem.
