Hey guys.

I'm looking for recommendations for a heavy duty servo, the same size and power requirements as the EZ-Robot HD ones, but at least twice as strong in regards to torque and holding positions, and that will also play nice with the EZ-B.

I know that most, if not all servos will work with the EZ-B, and I have looked online to see what's available, but I'm hoping someone can recommend a strong reasonably priced servo you might be using and would suggest.

Thanks.

@Richard.

I'm beginning to think your right. I've had a good long net search without much luck, and the couple I did find were crazy expensive. The only one I did find so far that comes close to what I'm looking for is this. It's slightly bigger (at 6.5x3x5.7cm) but I may be able to work with it and look's strong enough, and not a bad price either...

Btw, I'm pleased that David C and yourself enjoyed your trip to the inner sanctum. Sounded like you had a great day at the office. I'm supper jealous, but maybe I'll get there, one day. :P

@robohappy.

Thanks for the link. I saw the servos you were talking about, but I'm looking for something to run on a 7.2 / 7.4v set up. I did see this however this which doesn't look to bad, and the price is right.

@Dave.

Thanks for the recommendations Dave. The HS-7950TH is a bit on the pricy side as you say (but I've seen worse though), but does look a lot more like what I'm looking for so it's something I just may conceder. The gear boxes do look like a great option, and something I may consider investing in for a future project, but for what I'm looking for now, I have space restraints so unfortunately these I wouldn't be able to use one of these.

Thanks guys. :)

Wow, nice find @Dave... but the price!

@Richard.

Yeah I gotta admit, that's the one thing holding me back from ordering one. Price.

@Steve.... Can you not use a cheap geared DC motor and potentiometer in your joint that you are controlling? However, I realize servos are more of an elegant solution to moving joints....

@Richard.

It was something I considered a while back when doing my K-9 build, to control the neck mechanism. It may be something to look back in to, but as you say, a servo would be a more neater way of doing it. I reckon the 40kg-cm servo I linked to in post #7 may do the trick, but I haven't seen many reviews on it which is something I would like to check out if I was to spend £55/$77 on one.
