Thank you very much. You can find all the software and manuals at www.anninrobotics.com/

@@flyerminer the video is quite a few years old, those are analog drivers that were extremely noisy. If you check out the latest version of the AR4-MK3 that's almost silent

@@oithetresen609 I believe my machinist currently makes a couple of the parts on a 5-axis but I believe if you do the setups right you should be able to make them all on a three-axis

I did see his video. I sent him this response in the comments: @Thomas, Thank you for building the AR4 and highlighting some of its features. I did want to touch on a few of the comments you made. In the overview section of the manual I do mention pre-applying solder to wires being joined together - I find it easier to pre-apply solder or tinning the ends - and then bring them together with the iron rather than trying to hold the wire ends together and hold the solder and hold iron at the same time, not having 3 hands - it helps to pre apply the solder. None of the wires going to the breakout board call for tinning so I'm not sure about your comments on that? On page 143 I do have some groups of wires soldered together to help group them going to the 3 screw terminals as its a tight fit and difficult to maneuver them into position without them being connected but you could certainly use ferrules in this step if needed. At one point in the past the design did utilize plug connectors and building a wiring harness. Given different applications, motions and articulations all the low cost plugs I sampled proved to fail over time. With this small arm and the limited cable routing and cable arc lengths, direct solder with the solder joints in strategic locations using heat shrink proved to be more reliable, less bulky, less costly and not as time consuming as crimping and inserting numerous plug pins. The primary goal of this project from day one has been to realize a usable robot and at a very particular price point. I've worked with industrial robots my entire career and its always been a frustration that any usable robot was out of reach. There is an absolute threshold on the price as most educators have a budgetary limit so I have made it priority number one to stay under that limit. This drives many of the design aspects, The motors for example are off the shelf variants and cannot be fully customized without adversely affecting the price. There is a limit as to what OMC can customize on these coming from the factory. The machined components are kept to an absolute minimum and as many as possible are cut from flat sheet material. This also drives the bearing designs and tensioning designs as custom machined threads and spindles for locknuts for example is not in the cards at this price point. It also drives some of the belt selections. I did notice the belt tension on your build was far too loose resulting in a good amount of play. Here is a quick video of the forced deflection on my build. kzfaq.infolf_KFFiCdJA - Making the statement that "This robot arm is neither accurate nor precise, rigid or smooth" seems a bit harsh considering. A great deal of effort has gone into this project, I know you have a great deal of experience and a wealth of knowledge in all manner of machines and mechatronics and your design suggestions are certainly well founded but I wanted to explain these aspects of the project, and hope you will convey these points to your audience. Thank you.

@@classicskatespots1 if there's gasoline in the carburetor it'll run off the carburetor otherwise you just run it out of gas and then switch it over to propane or natural gas.

thanks!

Thank you

Thank you!

happy to help. Thanks!

Thank you!

Total cost is just over $1900 to build the robot, let me know if you have any other questions.

@@anninrobotics i wanna build it, but im in Europe, can i buy the whole kit here?

@@Tjup Yes I ship UPS worldwide.

Thank you!

You will need the AR4 motors kit from Stepperonline and the robot combo kit from Annin Robotics. Have a look at the robot kits page which covers everything needed. Total cost to build the AR4 is approx $1900

Yes you could

It would take some mechanical changes but yes as long as they accept pulse and dir inputs

Thank you!

Hello, the reach is 63cm. There are also some drawings in the manuals specs chapter that might help. Thank you.

Thank you so much!

Thank you!

I just installed a thu beam sensor and a relay to stop the conveyor

Thank you.

LOL

no problem I'll approve the requests tonight. Its unfortunate I have to approve all the users - otherwise spam bots take over the forum.

@@anninrobotics That does sound like a huge pain. Thanks for building a place for us to commune. I look forward to joining! Also, do you happen to have a Discord community?

@@anninrobotics Thanks! Just got access!

Their isn't an equivalent kuka

@@Z-add Kuka munga?

The closest Kuka would be the KR4 agilus. I think the AR4-MK3 is pretty decent given the goal of making a low cost robot that anyone can build at a cost of just under $2k for a full aluminum version but its not going to be quite as good as a $20K industrial robot. I'll keep working on it though!

Thank you!
