Hey guys!

So, my intention was to replicate an industrial robot arm with 6 degrees of  freedom, I am pretty satisfied with the result. As I do not have any Mindstorms, I decided to build it only using Power Functions. For operation, I use 2 sBricks, which allow me to do precise movements, from an interface of my own design. Most joints have a large movement range, it can lift up to 150g of weight and the operation speed is intentionally slow, for better control.

The arm uses 7 motors, which can all be controlled independently. It has 1 XL, 3 L and 4 M motors. The arm is powered by 2 battery boxes, a large one in the base and a small AAA on the custom turn-table, which I am very proud of. By the way, the total weight is 2800g, so quite heavy. It actually took me one month to create, so it's definitely my longest build to date.

But enough talk, here's the video (you maybe saw it on FB already).

Here's what you can do with the robot arm, using a nice sBrick sequence:

Great work man! looks very interesting.
Would you mind sharing some pictures of the internal mechanics?


Thanks a lot for your comments, everyone!

While I would love to share some internal photos, you cannot see much, unless I take some panels off. I will try to handle this soon :)

Check out my 2nd video, where I demonstrate the power of the sBrick sequence control. Enjoy!
