I have a robot which I built recently, and I am now going to add the 4 DOF arm to it (servo erector set). I am not certain which electronics to use and how to control the arm wirelessly. can anyone please tell me how to do this and what electronics I should use as well as the mechanical parts for this set. I would appreciate it a lot.
Thanks.
Unlike most forums, this one is small.
Since we only get about 30 posts a day, most members read them all.
So there’s no real reason to post in multiple topics.
Let’s see…
There’s no real assembly guide or parts list for a 4DOF Servo Erector Set arm, yet.
At the beginning, the SES was made like legos.
You buy some, play with them, and figure out how the get put together.
The assembly guides are only a recent addition.
I can, however, give you a better idea of what you’ll need.
For every servo, you’re probably going to need an ASB-04.
Those encapsulate a servo and allow other brackets to attach directly to it.
To connect servos together and give them a joint to bend at, you’ll need “C” brackets.
You’ll probably use ASB-09, but there are a variety of other “C” brackets that you might prefer more.
And, you’ll need a gripper.
Right now, there’s no large SES gripper (the one on the site is made out of lexxan.
However, you can easily devise your own.
Here’s a link about a 3DOF gripper that Jim threw together.

Don’t worry about the necessary hardware for your project; all that is included within each parts packaging, plus extras.
You’ll also need electronics:
The SSC-32 and/or the BotBoard with a microcontroller.
A battery.
A male battery connector.
A charger.
I agree, cross posting is not good practice, especially since this forum has moderate traffic like Mr. Reiser pointed out.
With any bot project, careful planning is key. This is not something to jump into and start slapping parts together. You need to figure out what the main goal is and work off that. In my case, I chose to focus all of my attention on the head design and functionality as my primary goal. Every day I review my design and change/tweak things as I discover new problems, new ideas, etc. Had I jumped into things and rushed things along, I would have a nice collection of paper weights for my desk at this point. 
The assembly giude for the 4DOF arm is found in the “What Can I Build page”.

The arm can be controlled in any manor that the L5 can be controlled with. There are options in the Assembly Guides section.

One wat to control it wirelessly is found here.

However this tutorial can do the mobile base AND the arm.

Hope this helps…
