Hello,
I would like to buy an Open Manipulator -X robotic arm. it has servo motor. I would like to position the robot by manipulating the arm, that it records about twenty different positions, and that I can record this sequence so that it repeats it many times with a stop at each sequence.
to explain otherwise, I move my arm in a certain precise position, I record each of them. I then obtain a program which will make me the sequence which I have just done with for passing from one position to another the obligation to press a key.
can you tell me if it's possible and what i need to do that.
thank you in advance
You need to post a link to the datasheet or user manual for the "Open Manipulator -X robotic arm"

That's a very expensive device so please do NOT make a decision based on my comments.
I suspect you could use software (with buttons or a joystick) to move the robot to a position and then record that position and subsequently send a simple instruction to make the robot move to that position. But I don't KNOW that that is possible or how you would do it.
It seems to be possible to control the device directly from a PC if you have the OpenCR controller and that might be the best option with such an expensive product.

Since they have a demonstration of doing something similar with a PC and two arms (manually move one and the other follows), and they provide an Arduino library to control the "Dynamixel" servos, it appears to be possible to manually position an arm, record several positions, and run that same arm through those positions in any order, repeatedly.
One thing that is not clear yet: Are the encoders absolute or relative? My impression is "relative". To get that to work you have to position the arm to a known starting position before turning on the power. If power is lost, the position is also lost and the arm will have to be manually repositioned to the starting position.
They do in fact have example code that does precisely this. You might have to email their customer support but they do have code that can save and replay actions. The only issue as stated above is that the position is relative, not absolute so you would have to have some sort of home sequence to give the arm a proper reference point.
You also need to record the time that is needed for each move and allow that time to expire before making the next move. Otherwise you will be commanding move 2,3,4, etc long before the first move is done.
