Next time your bearings are alittle to tight to seat simply put the bearings in your deep freezer for at least 6hrs and they'll shrink a few thousandths and seat right in for you and once at room temperature they'll be nice and tight. I always engineer my bearing seats a few thousandths smaller to achieve this. End result is a great build with nice tight joints ect.. hope it helps some of you guys! 😊
How come i get recommended this after having spent 10 hours 3D modeling an arm that 90% looks like this one, youtube algorithm man god daym i'm impressed, i hope my design works nice robot boyyyy
If you make the base a "C" shape and use a bearing on the top and bottom of the first moving stage, that should correct most of the tilt problems from the base flexing.
Yeah, that's true. The "C" shape is good idea for getting better moving range. Though, that definitely would need to be made out of metal, maybe 2020 aluminum profiles, as a 3D printed one would be too weak for that application.
I watched this last night, then downloaded the files, and while I was going over them today, I realized you could make a better base by simple buy a small mill rotary table and motorize that to build the arm on top of. I got a big one that is too big for my mill....make a base for a big version.
@@Acemarcelo12 i see a lot of youtubers using fusion 360 (probably because it's free, or they're sponsored) ... Which is pretty good, but all professionals i worked with use solidworks
My first exposure to this robotic design (6 or so years ago) was in the context of a 3d printer. The main benefit being that the reachable area is several times larger than the robot's footprint, meaning that in theory it would be possible to print the entire robot (assuming tech to print motors and wires but for now just the plastic parts) entirely inside its printable area. In fact, one demonstration model I saw was able to print 3 complete sets of parts to build more. Very nearly a Von Neumann machine. The main drawback being that the complex nature of each axis needed to be considered as it's own coordinate set, each of which changed based on changes to each join from the tip to the base making it very difficult to calculate the highly accurate motion needed to print finely detailed parts. In other words, positioning was not calculated using kinematics. I look forward to seeing your experiments with 3d printing and laser cutting with your design. Your solution to finding a position seems elegant and I'm blown away! (but I'm an animator and not an engineer, so don't let my awe go to your head.) I would suggest basing the first joint on a much larger bearing and printing the housing with thicker walls. I'm sure you're far more aware of 3d printing engineering techniques than I am since I dipped my toes in for only a few short years and you are currently involved, so maybe I'll just keep the rest of my comments to myself. Love what you've done here, though!
When I was a student at university, there were only books to learn the someting. Even to find the right book, we would buy a few wrong books first :) Now I envy seeing such wonderful educational content, I wish I was a student nowadays :) Thanks for great sharing !
thank you for sharing your amazing project. I decided to base my own project off of it. I just a beginner in building robotic arms and in 3d printing. It is so helpful when there are people on the internet who share their work with newbies like me.
It makes me so upset that you are probably not making a lot of money from these videos, it really sucks that you are so talented but somehow don't have millions of subs. I honestly wish that you put more ads in your vids to make more money because you truly deserve it much more than anyone else on youtube
Woah! That's mind blowing dude! That's huge. I saw your video about the laser engraver and I was super impressed with this project and your will and dedication. 👏👏👏
You sir, are a genius 👏 .... This is exactly what I'm looking for and you have saved me a fortune for my low payload / precision robotic project. Thank you SO much for sharing your amazing expertise here ... 🇬🇧
Thanks so much. This is brilliant. I'm getting very interested in robotics and though I can write code I had no idea how how to start. This is an all in one solution for me to get started.
Two supporting bars as a triangle mounted to the wall, would removes the problem of the wobly operation and thus the accuracy and thus higher operational speed drastically. It would need a recessed hole on top of the 'roof' of the robot containing a standard bearing with a 8 mm hole.
sir ur project is amazing i am doing this scara robot i have finished the fabrication and electrical connection works but now i m struggling to upload program as i am a mechanical student i didn't know anything about programming so please give any guides to upload and complete my final year project successfully
Thank you for designing this Arm , I hope you don't mind me reverse engineering it for a school project ( Industrial Drafting). Hopefully it will turn out as good as yours. Awesome scara project and love your videos.
@NavySnow yeah, I'm fighting the belts atm. im printing the belts in tpu so there's alot of testing I'm doing also need to change a few design flaws it has
@Jake Of All Trades I found one on Thingiverse that has many makes and people who made it run into a lot fewer problems and is cheaper but much smaller. This one is very cool I just don't want to deal with troubleshooting.
nice job buddy. Appreciate your truth at the end where you said it was not as ridged as you thought it would be. Really appricitae the time and effort you put into your projects and for sharing
Inverse kinematics is a very cool topic. But the real deal requires understanding of partial derivatives and basic linear algebra. The idea in most systems is to project the 3d cartesian motion into the robots "joint space". Which allows you to see what a small linear motion would look like as small motor rotation. If you do this 1000 times for each configuration of the joints then you can get close to your goal position. Id love to get into details but hopefully a video will be released on the topic, the key technical topics you need to know are: denevit-hartenberg, jacobian matrixes and gradient descent.
It's a very good conception. You could have worked a bit more the cable management, but honestly, it's way better than other "awesome DIY industrial robot arm" you can find here and there. Well played!
dude, why didn't i find your channel earlier, you are fuckin awesome. In fact i would go as far as to say you have the best engineering channel on youtube (period). Your videos are so detailed and explanation are very much understandable. you are awesome keep making these videos.
18:59 And why are the cable colors so different from one to the next stepper? Did everything said in this video and described on the website and dont work ... the tutorial is so much missing to explain. Very sad :(
Hi, I finally built the Scara Robot. I modified all the 3D CAD models to accomodate with all the components i had existing from my other projects, and even added some 3D design features to simplify the routing of the cables in the interior of the Arms. I am using (4) 12mm linear shafts and flanged bushings along with a 12 mm lead screw and nut with lead 8mm and 2mm pitch. I have also designed a solid aluminum base frame structure which i am houing the power supply, the arduino uno and cnc shield, the step down voltage converter and fan and the ac power switch from the rear. The Homing sequence works perfect, the only issue i am having is with the gripper after homing in pde processing-- i am confused. When it fiishes the homing sequence the x,y,z are at 365,0,170. My z is slightly different than the one on Mechatronics due to interference with gripper and frame when homing stepper4 ( so i changed the code in arduino for homing of stepper 4 instead 0f 10000 to 17000 after limit switch is pressed, and the gripper needs to be in closed position- for mine 90 degrees. After Homing Once i drag the gripper value slider , it dives down in the z and hits the table. What can i change in the pde or arduino to stop that, it really shouldn’t do that, it should only move the gripper to where i want it to be open, closed or whatever it needs to be - why is the z moving also ?? .Your help would be appreciated. Also my Gripper is fully opened at 0 degree and fully closed at 90 degrees, thats the way my mechanism links work. My z travel limits are 0 to 182mm
Hey, glad to hear it you managed to build it. Well the issues you are experiencing with the gripper and the Z axis moving is true, I had the same problem but didn't put resolve it, as I already worked long enough on this project and had to move on. I believe it's something with the serial communication between the Arduino and the Processing program. The Arduino might not read the value coming from the program properly and that error of moving along the Z axis occur. Maybe try to use some if statements on the receiving values to confine to only real values. Also you can try to monitor what happens when this error occur through the serial monitor and print the values on it to to see what's the problem. I hope you will be able to solve the problem and share it so other people can learn from it. Cheers!
I love your videos, looking forward to more about this robot! What do you think is its maximum load? Or how would one even go about calculating that? You've definitely inspired me to make one of my own!
Congrads on project. I would like to point out that you have mistake in a forward cinematic formula, product instead of sum, shown in video, in 21:10 -> should be x=L1 x cos(fi1) + L2 x cos(fi1+fi2), the same is with y. Also if I may suggest, you can print large slew bearing for better rigidity of the z axis.
Yeah, nice catch! I have misspelled the sign "+" with "x". I cannot correct the error in the video, but I will correct the error on the website article. Thanks for the input!
Dude really dig the design here. For a first build its super. Now if you get a cheap CNC breakout board and a serial or usb port run LinuxCNC and all the control issues could be sorted. But the bulk of the value sits with the code for the control interface here. Well done. Thinking of building it.
Love the design, really nice. The only thing I would change is to swap out the claw head for a vacuum pickup (still swivelling) as that would potentially be more useful
@@HowToMechatronics I guess the main issue is swivelling the vacuum line in the head, and trying to make sure that joint then doesn't leak! But might then mean that you could use it for SMD component positioning, which then makes it a really useful tool
Thanks for sharing 👍🏼 I will do some kind of robot soon and like this idea. Will need to have a look at the backlash and stability concerns but it look great!
I will add this to my to do list....however the bearings and metal parts are so hard to find in my local market. So the procurement phase could be long and that is a barrier to my motivation that I need to override ASAP:
It would be simple to brace the vertical joint. Add a support truss to the top of the vertical and problem solved. Question. Any idea of the load capacity of this Scara design if the top was supported and the whole structure was made more rigid?
I have a question on your construction website I have noticed that there isn't any recommended electronics or electronic kits what electronic components do you use to drive the stepper motors and what type of stepper motors are they and what size
