uArmⅠ is a small Palletizing Robot refer to ABB PalletPack IRB 460. You can also use it as a robot arm and make a development of it to make more interesting applications.

In order to make it more flexible and easy driving, I have also designed two kinds of Chassis of the robot arm.
One is a simple 2WD car as you can see in the following picture.


The other one is a 4WD car. I have added 4 Shock Absorbers on it as you can see in the following picture.


So you can install the robot arm on the Chassis and use this platform to do further applications on the ground.
Next, a special gripper for this robot arm is in designing and will be updated soon.

Hi PaulS,

I have made the design and used the laser cutter machine to build the arm by myself. And I am making improvement of it now.

This is a pretty neat little arm; I like the fact that you put most of the servos at the base of the arm, rather than at the joints like you see so often (now, if you could do the same with that last servo - heh)...

I would love to have a copy of the file(s) for laser cutting; I just recently joined my local TechShop (Chandler, Arizona) and finished the SBU for their Universal Laser Systems cutter. I've got lots of ideas for things to build with it, but one more project wouldn't hurt...

Actually - I realize you probably aren't going to give away the files; it sounds like you are starting a business, so I can respect that. One of my future projects for the laser cutter is to actually build a clone Armdroid (well, as close as I can come to one given the information available on it) - but that would be a very complex project, not something I intend to tackle today!

Great job on your robots, though! I think the arm looks best on the 4WD base (seems like it would be more stable with a load, too).

Hmm - how about building a translational (linear movement) base? Such a base movement system is often used in industry for assembly line work and other work where the arm needs to translate linearly along or with the work piece...

I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.

Hi cr0sh,

Thanks for your suggestions. We are now make an improvement of this robot arm and your suggestions are quite helpful for us.

As we call this open source robot arm. So of course we will make it open and release both the design of the mechanical and electronic with the final source files after we finish this project.

If you want to build one by yourself, we can send you the files after we finish the project. So that more and more people can join us to make a better robot arm and further applications for this.

Thanks for your suggestions again.

We have made the second version of uArmⅠ. In this version, you can change the head of the arm, so the fourth servo on the head of the arm can face down and forward by different install ways. A special robot gripper is in designing.  See more details below.

Here is the design which I refer to, the World's Fastest Palletising Robot - ABB IRB 460.

From now on, there are two kinds of choices for the head of the robot arm.
One is a sucker and the other is a servo for installing robot gripper on it. You can see two of them in the following picture.


On the other hand, there are also two ways to install the head to the robot arm. One is to face down and the other is to face forward. The following picture shows the parts for different install ways.


Install the sucker to the head of the robot arm.




Install the servo motor to the head of the robot arm.




The second way for installing.

Not sure where you are storing your pictures, but they are not downloading for me using IE,  I just get an X displayed. I like the design of keeping the servos off of the arm as much as possible.

Very attractive work, sincerely.

The fact of keeping servomotors in the base allows to limit the efforts on each, it is very ingenious.

The second test of uArmⅠ, in this version we add 4 suckers on the chassis of the arm to  mount it on smooth surface.
