Cheapest Best Micro Servo
« on: January 27, 2009, 12:29:33 AM »
I am looking for a place to buy the cheapest best quality micro servo, any suggestions.  I am thinking of creating a robotic hand, instead of a gripper for my robot and I will need small servos.

Those servos are of a great quality and they are the absolute cheapest you can find anywhere. I have a couple and they work great.

Thats exactly what I was looking for, thanks.  Does that servo have three pins, so that I can use it with the Axon

Hi,

Did you consider "Muscle Wire" (NiTiNol or similar)?
Would be much easier to fit.

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?

Yes, it has a standard hobby servo connector like most other servos. I also got them and they are great. I have one I use for testing my servo controller and by mistake I have pushed it beyond it's limits with grinding gears as a result, but it doesn't seem to have taken any damage. And if it breaks, they have replacement gears: http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=4950&Product_Name=HXT900_Replacement_Gear_Set

Doesn't that tell you that it is a common problem with these servos and therefore not something to be used where they are hard to get at (like inside a hand)?

not necessarily true. Everything wears down eventually. Even the expensive metal gear servos have replacement gear sets.
Check out the Roboduino, Arduino-compatible board!

Sure, even NiTiNol wire does (used within specs they should last longer than any servo however), but plastic wheels doesn't strike me as my first choice in a robot hand and the wires makes for a much sleeker design.
