Hello Kass!
I want to use a power based shield for my project to power the four servos... Which one do you advice
me?
Can I use this one?

looking forward to hearing from you

I made my own shield

You can use this one although there are cheaper alternatives

here is the error message, i am sorry but some things are in portuguese.

You need to install the VarSpeedServo library in your /Arduino/library folder
hi kas, with your help and with the help of everyone here i was able to build the structure and upload the code to the iteaduino board.
but i still have questions about how to power the servo motors so if you could show me how to connect the servos to the board it would be great.
thanks.

Adapt for four servo's only
I use two LiFePO4 batteries (6.8V) for powering both Arduino and servo's
The safe way is to use separate power supplies (9V + 5/6V) to avoid browning out
Don't forget common grounds
EDIT: this drawing is for connection description only
Please don't use a solderless breadboard, wires should be soldered
How many amps can go through the positive rail in a solderless breadboard? Should the power current carrying wires of the servos be soldered directly to the power source instead of through the breadboard?

Sure, solderless breadboard shouldn't be used
I edited my post accordingly
hi kas, i am having some problems with the code, when i power the servos they start moving on their own.
maybe i am connecting the servos to the wrong pins, can you please explain me a little of the code ?
the servos they start moving on their own.
Please be more specific
Post connection diagram and a video showing those moves
i follow exactily the image you sent me, but the moment i power the iteaduino and the servos they move and lock in place, i bet i am connecting the servos to the wrong pin on the iteaduino.
and i also am having a problem with the app, if i connect the app with the iteaduino when i try to scan the app crashes.
i hope you can help me because i am almost out of time for my school project.

According to CubeMover13_posted
"down" gripper:
#define downPinchPin 9
#define downRotPin 10
"back" gripper
#define backPinchPin 5
#define backRotPin 6

ahappykid, I am not convinced you fully understand what you are trying to achieve :
You should probably go for an easier project
Hi Kas
I have just recently found this project and I have decided to give it a go. I will retire soon and my plan is to start this in the autumn after the clocks turn at the end of October, so that I can get it ready for Christmas. It can be my Christmas present to myself. Meanwhile I will set about collecting the bits and pieces needed ready for the start date.
Being as you have been very helpful to people on this forum I was wondering if you would be kind enough to sell me a pair of grippers ready for my project.
If you are happy to do so I would prefer clear plexiglass, acrylic or perspex as a first choice, then as a second choice plywood.
I would be happy to pay the going rate for these items if you are prepared to produce them for me.
I have made a few projects with the Arduino in the past so I should be able to pick it up again with not too much difficulty, at least I hope so. The last think I did some time ago was a device to replace a timer switch to switch on a security/welcoming light which automatically changed the on time according to the time of year using an algorithm based on the equation of time, rather than an LDR. I have no experience of servos, but I have thought of learning to use them for some time and this seems like a good excuse to start with.
Many thanks mach1
Hi mach1
Once retired, you will soon enter a very busy time, trust me on this one 
I don't own a CNC machine anymore
This project is a nice opportunity for you get into the 3d printing Universe
Files are on Thingiverse
A good printer can now be had for less than $200
My advice: get familiar with servo motors first and spend time on the test bench before building the final prototype

Thanks, will do.
Hi Kas
I am slowly assembling what is needed for this project. What do you think about this as a power supply:
8.4 V to power the Arduino, 5 V to power the servos.
By the way I am heading for the Android route. Any chance that I can have the app now in readiness?
Thanks.
Hi Mach1
This device with 6 X 18650 batteries will be OK, but is pretty much overkill for the job
Same with two batteries only will be 100% acceptable
I power my own bot with 2 X LiFePO4 batteries
6.6V is slightly out of spec for both Arduino and servo's, but it works pretty well
End of technical support
I have been supporting this project for nearly four years, this was an exciting experience
I have since moved to other projects and it's now time for me to retire
All possible questions have been answered in this thread, just read it
