Making Servo rotate 180 degrees

Hello.

I am part of my schools robotics team, we had just finished the first part of a robotics competition, we made to the top 4 and now where going to Alabama for the final part of the competition. The Robot performed well but not well enough, but luckily there more important things then the robot performance. In the competition we have to pick up these subassemblies that when put together make a small plane. We have the a gripper that we want to open more but the servo only rotates 45 degrees and we want it to open 180 degrees.

We have a Futaba S3004 Servo.

Use gearing on the output of the servo, so the servo moves 45 degrees, and the output of the gears moves 180 degrees.

Ah.. sorry. I forgot to mention that this needs to be done through the robots brain with the C++ Program.

By increasing the width of the pulse beyond the spec you can increase movement somewhat - but nowhere near 180 degrees - you need to do it mechanically.
