For the thermal switches, you can easily put an LED with a resistor in parallel with each thermal switch. If a switch trips, the appropriate led is going to illuminate, so you can find which thermal switch tripped.
Thank you for the backlash segment of the video and upcoming joint testing! Great job putting this together, I will definitely be watching the upcoming videos on the further testing/design iterations! One idea that hasn't been addressed with 3D printed gears on youtube (yet) is applying a wear coating to the gears (something like a low-friction paint) - to allow tighter tolerances for less backlash without significantly increased wear rates. I think this, combined with grease, would be a really interesting long-term test after the upcoming individual joint/force/wear tests!
Nice clean looking build. I've become quite partial to timing belt actuators to avoid the high backlash from 3D printed gear actuators. When properly tensioned, timing belt actuators have essentially no backlash, and only a little deflection under load from belt stretch. With some gravity compensation on the shoulder joint, you could also get away with a lower gear reduction.
TIP for Everyone, if you print hollow shells; you can pack them with glass-resin, to save time and increase strength ! Amazing build, love the custom driver stacks too !
Incredible project! Great work! Thanks for your contribution on the 3d printing and diy Robotics community! I hope that you get the recognition and exposure that your content deserved
It looks very nice. The PCB tower looks cool but, I am afraid that the motor drivers are going to get hot, maybe heat-sinks should be added and a fan for the enclosed space. Backlash seems quite high, but I'm waiting for the next video with more advanced movements to see how much it oscillate when it moves.
I think you're doing a good thing by pushing forward 3d printed actuators. Backlash could be too much for precise applications, but that's to be expected
With the metal acting as a thermal mass, it might still melt if the melt temp is reached on the motor. If you set threshold lower, then it will take a long time to turn back on. It seems like eventually you'd use the thermal switch as a failsafe only and calculate the safe duty cycle which would always be in effect?
I'm trying to print a robot arm, there a couples design around, i wonder this is better or the moveo that everyone seem to be printing the moveo cost around $600 -700 buck to build. This seem look to be much cheaper at $150. There also some harmonics drive that is gaining traction's, very exciting.
I would have really loved to watch you solder those motor drivers and the Teensy. Those boards were pristine! I would definitely watch a soldering tutorial from you!
Holy crap that's glorious! Would 5 axis be good for getting cool shots with a camera? My brain sucks at figuring out the potential movement paths lol. If it is then a cool idea might be the ability to add keyframes for setting up a movement path. Maybe a rotary encoder to first dial in how many keyframes you want, then a button to set a keyframe, and a little display to show you how many keyframes are left to set as you enter them.
super-cool! So glad to see you doing affordable projects ... the videos with expensive drives have unmotivated me recently- but I think I'll be joining your patreon now! great work! thanks!
Hello mr. @skyentific, do you plan to do a tutorial on inverse kinematics and trajectory planning on this robot? There is not a step by step tutorial on youtube about these topics, especially on 5 dofs robotic arms, you could be the first one
Two ladders or a few 2x4's of wood, with rails on the sides of them to create a x and y axis, with a spray painter on it. You can place it against a wall like a ladder normally would, and hit PRINT, and it either coats the entire wall in controlled even passes, or draws a photo painting from a file you send the gcode. Cost? could only be just a few dollars if anything, if you already have the basic materials. Use it to become a tireless exterior interior wall painting employee that you only pay with buckets of fresh paint.
The problems I have found with lever switches is that they are too flexible. Maybe imprecise? Reed switch, may be better, but a photo switch can be rather precise. Many outdated automotive switches available.
Recently found this. Im thinking mounting it to my ceiling and using it to grab nuts/bolts kind of thing for me. Would be cool to us AI voice actuated to initiate the part pull.
What are those green wire connectors called guys. I have some but when I search I just get the normal ones. I'm building it and donating it to the local non-profit makerspace I volunteer at. I've paid for all of it and it's not expensive if you take your time and order the parts a few at a time. I'm going to paint the grey pla. I've done it before and it looks like metal
In worst case I will add fan to the base. But I already used similar drivers in my Igus robot video with Nema23 motors, and the drivers stayed cool. So I don’t expect them to heat up a lot.
I am not stepped back. I still plan to use BLDC. But BLDC controllers way more expensive than stepper controller (around 100$ for BLDC vs around 12-20$ for stepper). So with BLDC, 5 axis arm would cost 500$ only for electronics. So to keep everything cheap (as many of my viewer require) I used steppers. But I have several BLDC projects on which I am working now.
@@Skyentific Glad to hear that, but I also noticed the price of the controllers, and I even bought a very "cheap" Odrive clone on aliexpress... Great projects, thanks for your work!
did you try first before going to change the motor just jank up the current? or did you just stick to a recommended value (will make the driver and motor hotter ofc and need active cooling for driver possibly and all of that..)
Hohoho i like your laugh! Also i just finished printing an arm that uses servos, next time I'll try with steppers, great video as always, I'll check your cad and code, also can you give us a tutorial on how you do inverse and forward kinematics, looking forward to it!
Without screw and nuts it cost around 150$ (if you use cheaper drivers from 3d printer). Each motor is less than 10$, all the bearings is less than 40$. And you can get stepper driver for less than 10$ per driver (I use here more expensive drivers 20$ per driver).
This is just awesome! This summer I would like to make a project like this with your STL files, but the electronic parts seems rather big for a beginner. Would you suggest a small project to start with?
Check out Michael Klements DIY camera slider, I'm currently working on one for my first project and it's got a lot of the same DNA as a build like this robot arm.
Awesome, watched all the way through. You go through some PLA, sir! Guessing you're not buying it 1kg at a time, maybe those 5kg texas spools? Now if you can just flip the arm upside down and make it self-balancing, and put your eyeball on top of it! :)
I used these ones: www.distrelec.ch/en/micro-switch-csm405-5a-1co-25n-roller-lever-camdenboss-csm40550f/p/13570364 I am sure that you can find similar at DigiKey. These are super popular form factor, thus there many manufactures.
Can you suggest me an encoder for my clg project where do a arm exoskeleton I have selected a higher torque dc motor From automobile wipers . Now I like to control its position very precise and accurate but I need encoder which will be flat and small as I don't have enough space to mount normal rotary incremental encoder which are in shape of small motor Range of motion 180 Speed- 30 rpm max
The backlash mde me think of the Adam Backstrom (murdered his name there) video about super accurate servos "How to make your servos awesome" happy to provide a link if you need it
this was interesting to see. im building a robot myself too and a friend recommended me this video. I love the idea of testing the axis using a joystick. I have one issue tho. my motor is not skipping steps, but after trying to go to the same directions for a few times its getting more and more inaccurate, like if it would drift or something. any ideas?
you know... I may have to sub to your patreon to get those files... im curious how well they'd do in ABS (i don't print PLA, ONLY abs and petg) or if I mill them with the cnc in aluminum... might be nice to have a robot arm in the workshop to hold things for me while I weld. lol

I always print the elements that come in contact with NEMA with ASA (ABS is too hard to print)
You should install cooler fan into basement for cooling drivers!

Is there a video on using the robot with python and pi?
Awesome video as always. Aldo you print the parts at home or do you send them to a tied party printer company?
Thank you! I print all at home. I have 3 printers. Two with 0.4mm nozzle for prints where I need quality and one with 0.8mm nozzle for big parts.
Great work
looks awesome!! the only thing I can see going wrong is that there is no thermal management for all the drivers...
In worst case I will add fan to the base. But I already used similar drivers in my Igus robot video with Nema23 motors, and the drivers stayed cool. So I don’t expect them to heat up a lot.
Great video! Interesting choice of music! 😆
Is there a reason you stepped back from using BLDC and stepped towards stepper motors?

where can we get more info on the stepper controller?
Would be interesting to see how you would interface this with ROS after all the software is done.
How much does it cost all together? Even a rough estimate would be nice.
Without screw and nuts it cost around 150$ (if you use cheaper drivers from 3d printer). Each motor is less than 10$, all the bearings is less than 40$. And you can get stepper driver for less than 10$ per driver (I use here more expensive drivers 20$ per driver).
