Learned Arm robot , Need your Help and recommendation

Help & Support Professional Robots

Hello ,

I am having a project for university ( in a team ) and we really need your help :slight_smile:

Our idea is to make learned arm robot using ( AI , ML , Image processing ) ,

Our first step we will make the micro or computer record the path then redo it again with wired connection ( parallel or serial ) and synchronous between the motors

Like that : youtube.com/watch?v=Z6feT_BhCVc

Our second step is to using Artificial Intelligent and Image Processing and make the arm define the object and do process on it ,

Exactly Like that : youtube.com/watch?v=k8cgXejV8kg

But at start we will do this in small arm and small objects ( application ) ,

So I have found this Arm in Your Shop :slight_smile:
robotshop.com/lynxmotion-al5a-robot-arm-combo-kit-4dof-3.html

Our questions are :

1- Can we do that idea using your Arm ?

2- What is difference between ARM options Hardware only and no electronics ?

3- we need the mechanical ARM with all servo motors no software needed , how does it cost ?

4- In this Arm is there any circuits , Micro , chips , and the torque of the motors , How can I know all these information ?

5- Is there any Recommendation Please ?

Finally ( and I’m really sorry ) We are students at engineering faculty ( Egypt ) and we still learn Image processing and AI , Ml , we did Micro projects before , we know maths and DB … , and we Eager to learn and try this idea , But in your opinion Can WE DO IT ?

I’m waiting your reply sir and I am really appreciated for your time and help :slight_smile:

Thanks ,
I really appreciate for your time and help :slight_smile:
But I need More information about Robot in this link
robotshop.com/lynxmotion-al5a-robot-arm-combo-kit-4dof-3.html
Is there a version of it with 6 degrees of freedom ?
If yes, how much is it?
Also,what about its feedback system(using encoders)?

And generally
I’d like to know more about your 6 degree of freedom robots and their features?

Also,regarding this robot
robotshop.com/dagu-6-degrees-of-freedom-robotic-arm.html
For the arm photos are they optional or what?What about the use of the kit in the photos?

I am waiting for your reply.

Best regards,
Ayman

I mean this Arm : robotshop.com/dagu-6-degrees-of-freedom-robotic-arm.html

There are some photos in it’s page like :
robotshop.com/ProductPictureViewer.aspx?id=25245
robotshop.com/ProductPictureViewer.aspx?id=25255

which one can i order and are these designs the same cost ?
also this servo controller robotshop.com/ProductPictureViewer.aspx?id=25247
Is it included with the arm ?
Finally How long will it take to reach us in Egypt ?

Hi ayman007,

Welcome to the RobotShop Forum. In order to make a robotic arm which learns based on the way it is moved, it requires some sort of feedback mechanism (optical encoders for more expensive ones, or potentiometers for less expensive ones).

  1. All of the hobbyist arms we sell are servo based, and as such do not inherently have any feedback, however it is important to note that a servo does have a potentiometer built in, so there is the option of hacking it so you get the feedback signal.

  2. You are likely talking about the Lynxmotion AL5 series; the “hardware only” version does not include the motors or electronics, while the “no electronics” version includes both the hardware and the motors, but no controller.

  3. You can see the price online (choose the complete kit). The software is included by default and you do not need to use it.

  4. There is no direct way of getting these measurements - you usually have that kind of information on much more expensive industrial arms. You can get a sense of torque by measuring the current to each motor, and a sense of the position by hacking each servo motor to get the potentiometer values.

  5. In order to do all you want out of the box, you would be looking at a much more expensive industrial robotic arm, otherwise you will need to hack each servo and add electronics to these smaller hobby robotic arms. Only then can you concentrate on the programming and image processing.

If you want a feedback arm, you may want to build your own using the proper servo motors and brackets. RobotShop offers a range of specialty servos, some of which provide positional and torque feedback (namly the Robotis line of Dynamixel). You would choose the brackets you want in order to make an arm. We offer a few controllers (Uptech Multiflex, CM-700 etc.) which can control the servos.

Hope this gives you some ideas,

Hi,

The 6 DOF version only adds the wrist rotate feature (sold separately as either light weight or heavy weight). You can see the prices online. Also note that you can add brackets and servos to create however many degrees of freedom you want, so long as each motor can provide sufficient torque.

There is no feedback system on the AL5 arms, so you would either need to hack the potentiometer, or add an encoder (somehow… we don’t have any particular model or instructions as to how to do so).

Which robotic arms are you interested in? Can you specify? It’s quite broad as a question…

The principle of operation is the same as for the AL5 series - using servo motors. Not entirely sure what the question is.

Hi,

The arm does not come with a tracked base - it comes as shown in the primary image; complete arm, stationary base and controller. The other images simply show how the arm can be used; if you would like to add the arm to a mobile base, we would be happy to help, though you would need to make a custom plate to connect the two. You can calculate shipping to Egypt by adding the product(s) to your cart and clicking “modify my cart” where you will be prompted for general information; the system will then automatically calculate your shipping options, time and cost.

Hope this helps,
