Using old servos

[qgeissmann]

If you used the old servos we have:

• we solve Servo lifespan #1

• we need new pulleys as their axis has different diameter (so we reopen new pulleys #4 )

• we can rotate 180 degrees (instead of 150).

  I just tested them with the lynx motion. works great.

Solution: We need to modify the design of the pulleys @pepelisu (larger axis diameter).
