Hammers??? Noooo!! that'll destroy the bearings in the motor. The correct way is to use a file to make a flat-spot on the shaft. Then tighten the pulley setscrew onto the flat-spot so it has more than just friction holding it on. If thats not enough holding force, then theres probably another problem. locktite may work but youll have a pretty hard time getting it off later and it can seize up the motor bearings if your not careful. Other than that looks like a lot of fun!
I really like the fact that you are using the Pi and the touch screen. Very good indeed. One small suggestion might I suggest that if the arm is going to to do a lot of repetitive joints you might want to use a temperature controlled iron and add a "wipe / clean" station.
We would like to thank everyone for their support on the robotic arm series! We have one more video planned. But don't worry! We have a lot of awesome projects coming up.
Really cool arm! Love the controls, FYI the holes on wire strippers near the middle screw can be used to cut screws to length (ie at about 2:30), Keep up the awesome!
Hi, awesome videos! I was wondering if there is an issue when you try to set the arm in startposition. How can you ensure that it will set in the exact same spot after it has done a task? I know that on my 3D printer it also uses stepper motors, but there is also a limitswitch to ensure that the position is indeed correct.
Like the series so far, one thing I would love to see is some test on the working weights the robot arm can lift and move, as well as how much pressure the griper and arm can handle. Thanks
Yes we had this planned for next video. The gripper has a surprising amount of strength. However, we were experiencing a lot of slipping. The heaviest thing we tried to pick up was a full beer bottle. The gripper could grip it, but the wrist motor was unable to turn.
Hello I hope I’m currently taking on the bcn3d moveo robot arm for a school project and I was having difficulty ordering the correct motors and after market parts. Is there a website that offers all of the aftermarket parts listed on the BOM. Any resources, links or advice you could offer me would be greatly appreciated
when are people going to start making 3d printing robot arms? They would probably have to be slower than regular 3d printers, but they would probably be able to have larger build volumes more easily.
You need to find an algorithm for the arm tip to reach any 3d coordinate in space at any given angle on its own calculating by itself which stepper has to rotate how much degree and in what sequence.. Then you have the industrial robot ready.
Are you gonna implement absolute rotation and IK to have the end effector move about in a more interesting manner? Also, does your program got access to the current position of the each of the axis? If it does, maybe you could use that to detect load and make it able to grip things regardless of size without breaking them, and also grip tighter for heavier things? edit: Oh, and if you can detect the exact position, would it be possible to make it compliant, letting you position the arm with your own hands?
I want to get into robotic arm technology I am very conformable in python and currently in big data industry where can I start learning about robotic arm technology?
how does it know the position you put it in? (as servos do not offer inputs I assume the arm itself doesn't know where it is) , is it based on the controller inputs? so it knows for how long you made it go down and where you stopped
AFAIK this robot does not use position encoders. So, using stepper motors, the software counts the number of steps from a place to another in order to move the robot from known point "a" to point "b". The issue that happens is if you ask too much power (or impede the movement somehow) and the motor "slips" (misses a step). You can see that happening around 5:27 in the video; dropping the remote hitting the desk pushes against the wrist and makes it rotate, which is unknown to the controller. The next run being relative to this new position, when the robot tries to catch the remote, the effector (claw) is nowhere near the proper position. Industrial robots in general use servo motors and position encoders at every axis. Encoders make the referential system absolute instead of it being relative, so movements are repeatable.
Hello, nice video serie! I printed and assembled a MOVEO arm myself, it's pretty much the same, unfortunatly, it lack some good software to use it and save position etc like you do in this vid. Which software are you using? could you share it somewhere? thanks you
Fakoleon, We are using software that works with the SlushEngine (roboteurs.com/products/slushengine-model-d) not ramps. Here is the code though: github.com/Roboteurs/rbx1-software
Hey Guys, seems like a fun project! But it seems to be very ugly to program the robot, because you have to control the rotatoric axles all by it's own to get to a point wanted. Isn't there a possibility implemented to work with a Tool orientated coordinate System? As an example your tool is orientated by pointing in a 45 degree angle to ground and you push the button for moving the Z-Axis down that the robot moves all Axis that are required by it's own to move the tool in a linear movement in its 45 degree pointing direction. I hope it is understandable what I am trying to explain. That would give the robot a much better handling. But to be honest, who would really need such a robot arm for privat? Clamping my soldering iron into a small vice would absolutely be enough and does the job... :D
Just sit tight. I think these two far-out brains are going to have this bigbot do extraordinary things with a soldering iron so they can make it a horrific desoldering terror in an unmentioned b-movie they're working on under wraps, in which it's programing will contract a wicked virus from a insanely jealous YT rival over somewhere in Shenzen China, run amok, and disassemble uncontrollably the electronics of fb headquarters data banks and that of the International Space Station...or something next to it.
Really? When it comes to electronics you don't think twice but when it comes to the simplest task of cutting a screw off that's the too complicated line? Come on guys....

Is it possible to switch out the hand part of it with a cnc spindle? It would basically be a 6 axis cnc milling machine for under 1000$!!!!!
Nice!
I'm almost done Thor, the 6 axis robotic arm. I'm definitely building the Moveo next!
Really cool arm! Love the controls, FYI the holes on wire strippers near the middle screw can be used to cut screws to length (ie at about 2:30), Keep up the awesome!

I really like what you are doing. Keep going!
This is epic guys, keep up the good work and thanks for showing the arm doing machine tending!
No worries! Thanks for the suggestion.
5:27 : this is why a robot should have position encoders.

The cheap wire crimper/stripper combo tools include a screw cutter.

good attempt guys, interesting project.
Nice robotic arm
Going to use inverse kinematics ? :)
Hello there. How much is the maximum weight that this arm can support? (for example, it can lift 1.5 kg)
You need to find an algorithm for the arm tip to reach any 3d coordinate in space at any given angle on its own calculating by itself which stepper has to rotate how much degree and in what sequence.. Then you have the industrial robot ready.
thats called inverse kinematics
That's some pretty cool stuff

Can it follow a path, draw or 3d make. I think it's possible.

Indeed with ramps it won't work, thanks anyway !
Could you tell me the stepper motor driver board specification , power supply and can we interface 8051 development board to control stepper motor?
You should have gotten the stepper with a flat machined on the shaft or break out the dremel or die grinder.
Just found this channel and i love it :D
Was the fan at the end also 3D prnted? Or do i actually have to buy one of those?

+SwarthySkinnedOne Okay okay. I think I can do that! Just hold my beer.
I need an elevator, ostrich and a shopping cart for kids.
Dope
Dudes make little flat spot on axle and put screw in the pulley never slips
Wat is the repeatability of the positioning?
What 3D printer where you using to print the Benchy?
What 3D printer was at the end of the video?
2:32 Would a 3D printed washer maybe help against potential wiggle in the future?
That is not a bad idea! If I have to take a part the gripper I will try that. Thanks for your comment!
whats the cost of such a project ???
Where to order that accessories?
What's the max reach and payload?
Does anyone knows what 3d printer are they using???
Wear can I get one of these from?
Why not buy a pulley puller?
Need more speed and better cable managment and hidden motors
🔥❤👍
But will it play doom?
Owesome!!!!
Can this be printed using PLA?
Yes for sure!
Thanks!
programme the arm to assemble more robot arms
That's what happens when you arm wrestle a robot arm, guys ;-P
how much?
:) i notice why you show the buton :
Turn this into a cnc device with a Dremel instead of a claw.
A 2014 Blackwidow Tournament edition?
Lol i have one.
give me link of componant or part
6000 steps to move a remote 6 inches, brain vs braun
what a smile! nice teeth
Theres a reason why stepper motors arent used in robot arms...
what kind of motors do robots use?
Really? When it comes to electronics you don't think twice but when it comes to the simplest task of cutting a screw off that's the too complicated line? Come on guys....
is this a hobby for you? and are you studying to become engineers?
Yes this is what I do on the weekend!
Great videos, but man why such a cringy name?
have you had your teeth whitened
Nope. I eat a lot of apples :p
the asian looking dude is cringing so hard because this other guy tries so hard to act xD
