Looking for a robot arm

Dear Sirs:
My name is Juan Crespo and I write you from Spain where I am a robotics
researcher. I am searching a robot arm for one of my projects, I dont have
any requirement regarding weight or load capacity or size, but I am
searching a robotic arm with a series of characteristics that I am not able
to find and I hope you can help me.
I want to control the robot from a external application running in a PC. I
want the application retrieving data from several sources (for example, a
camera) and, depending of the info, send motion commands to the motors. I
would prefer if I dont have to write the low level code for controlling the
servos. So I was searching for a robot that have any type of functions
library, set of DLLs or any other code that could be "called" from an
external application running in a PC.
Another question is that I am searching a robot with sensors, because I want
to know the position of the gripper with certain accuracy (I do not need a
extreme degree of accuracy, but I need some aceptable precision).
Please dont hesitate in email me if you dont understand any of my doubts -my
english is quite bad, I`m sorry- or if you need some additional info.
Yours sincerely.
Juan Crespo

Perhaps you can look at Yamaha robots

. Yamaha has only 4-axis SCARA arms. But they now have a controller that can be driven from a PC using Visual Basic, C++, etc. Your PC application sends the Yamaha controller commands in text strings.
Staubli

has 6-axis articulated arms. I was told that in the near future they plan to have the capability for PC control with their CS8 controller.
I am not aware of any robot vendor that allows one to program at the primitive motion command level. But I just have to ask....why do you want to do this?
For your gripper position, there are a variety of methods to do this: (1) in the past PHD Incorporated

had hall effect sensor options on their grippers. This option provided sensing capability for 4 positions (past-open, open, closed-on-object, past-closed). The last time that I used this was about 8 years ago, so I do not know if it is offered now. (2) You could develop some sort of analog or linear encoder-type of sensor arrangement on the gripper fingers to sense the exact position. (3) Grippers typically can be instrumented with proximity switches for open/closed sensing....this is standard.

Hello Moe... and thank you very much :)
But I wasnt thinking about an industrial robot. Because my project is more related to AI than industrial robotics: I want to have a very simple robot in order to show the capabilities of the AI -based software that we develop.
Thats why I was looking for a very simple robot, with no high performance requirements.
I think that Yamaha or Staubli (The "Mercedes Benz" of the industrial robots :) ) are robots too expensive for my project. I was searching for a hobbyist robot that could carry with it a simple feedback position system,or that allowed to incorporate it in an easy way.
After reading your answer, and another ones in my email, I think that easier solution is to buy some hobbyist robot and attach it potentiomenters in order to measure the voltage in the servos.
Thank you very much for your attention.
Yours sincerely
Juan Crespo
