Good Robot Arm and/or Hand.

I've been looking on amazon for diffrent robot arms like this:

or this:

But they all have terrible reviews, none of them on amazon are above 2.5stars. Any thoughts?

You might think about building your own it will be fun

No, I'd rather buy a good one. I have the money for a good one if one exists.

Hi,

I have not seen anything readily available on the market that I would say is good.

However, if you have or know someone with a 3D printer, there are a number of very impressive designs on Thingiverse. Of course it would require a substantial amount of work to get it working, but those are about the best I have seen. In a small desktop size range, there isn't going to be anything I would consider really good as in high precision, accurate motion, repeatable motion, etc. These size robot arms run on small R/C servo motors which due to their intended purpose do not have very high resolution.

I'm looking at getting one of these: https://www.littlebirdelectronics.com.a ... controller for a rover I'm slowly working on.

Any thoughts on whether it would be possible to remove the arm from the setup and drive it off a servo board? I had a quick look at one in store and from what I can tell its just a simple set of servos driving it.

Yea that one looks good and sturdy. I'd like to know if it is possible too.

I found it in a store and it looks like the joints are driven by dc motors. Wouldn’t even know where to start controlling with those as opposed to servos.

I wouldn't bet on it. Most reviews I have seen describe thesetype of arms as "toys" though they likely have some utility. It seems Maplins in the UK are currently selling them discounted at £30 ...

I had a play with a similar version which was manually controlled, perhaps a bit smaller than that, and it was extremely 'wobbly' in construction.

I have the money for a good one if one exists.

What exactly is your budget ?

I would guess this is one case where it is likely the more you pay the better quality one gets -

Apparently good one, but not in my budget to test.
