Servo recommendations

Can anyone recommend a strong servo compatible with Arduino? Ideally I'm looking for:

  • Speed
  • Torque
  • Compatible with existing libraries

I'll have a separate power supply, so the voltage isn't too important.

I'm a newb, so any thoughts/recommendations appreciated from those with experience.

Getting stared with servos

Some random comments:

  1. Get any “standard” servo that comes with an assortment of horns. Be frugal and experiment.
  2. Non-premium servos often come with very unobtainable Chinese specs. Don’t be surprised if your servo does not preform at the maximum limits.
  3. The spline on different vendor motors is likely to be different. Identify the horns.
  4. The fully digital models are quite a bit more costly than the traditional analog. The simplest units take a pulse wdith of approximately 900 to 2300 usec with 1500 being zero.
  5. Not all servos will span the full 180 degree range.
  6. Adruino and this site have examples.
  7. Post your success and ask questions if in doubt.

Update: What I bought

Hopefully someone will find this update useful…

I found these servo spec comparisons very helpful:

I decided on the HS-805BB Giant Scale Servo Motor

  • the specs are very good
  • the reviews are very good
  • the price is very good
  • I’ve heard the company endorsed
  • This servo is recommended for use with a particular pan/tilt system, which is another good endorsement

I also bought a HD-1501MG since it was cheap and high spec, with reasonable reviews.
