Can You also add image recognition or object detection to this robot?

Sir is your Machine Design is free to download in Solidwork?

[@paleogeology9554]

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! 😊

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.

[@HowToMechatronics]

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.

[@aimless3827]

[@jasonmccormick5968]

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!

[@Quantum_Dots]

Can you teach us concepts like 3D modelling ,how make 3d model to print on a 3D printer, inverse kinematics . I would love to learn from you

[@molomono9481]

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.

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.

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

[@HowToMechatronics]

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!

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!

Thanks! That's true, a was thinking of using a vacuum pickup but I didn't go for it.

[@JamesElise160]

@@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

Wow, I love this idea and design. I actually think I might be able to design and build my own. I think that constraining the topside of the robot with a second bearing will make it way more stable. The only downside being that the robot will not be able to make a complete 360º turn, but who needs that anyway, it's base is in the way anyway. Hmm, I have lots of motors left and a ramps with older stepper drivers. I should give this a try when my 5th 3D printer (a Prusa MK3S clone) is finished.
