3D Printed Delta Robot (Arduino Controlled) 2019

[@baylinbridges3069]

I want you to know that I'm thankful for people like you who are kind enough to share this much knowledge. Subscribed & looking forward to the next videos!

[@stevenchasteau8514]

Another brilliant piece of work, two things i particularly like; 1: Great detail and useful information. 2: It's green 😊

[@Thricenol]

Looks great man. I'm currently working on my own design of a delta style robot and i'm very grateful for how far you went to keep this information public. I have seen so many people show off what they have done then hoard the "how I did it" like it's supposed to be some big secret. The specs for the servo you used say that it uses a potentiometer. You should be able to attach a wire to the center pin of the pot and extend the wire out of the servo and attach it to an analog pin on the arduino to get the position of each servo. When you want to train the robot to do a motion, first disable the servos so they go limp, then move the arm to a position and record the position. There is a video on KZbin of a guy that built a very shaky arm using servos like this.

[@hernandobolanos798]

Thanks . You are so generous people. the spirit of open source and open knowledge are in you my friend.Nice project.

[@JaraFPV]

Me and my neighbors are so delighted and wondered with this technology. This will be so beneficial for the future of our rural life. Thank you for posting this very wonderful invention. Now I can teach my neighbors how to draw a circle.

[@davidduarte2588]

Man I hope you get a lot of subs, your videos need to be seen globally! Keep it going, regards from Honduras

[@-robo-]

Thank you very much. Not only for the printer, also for all the ideas inspired. Here is an idea to consider: Use a flex cable to move the end effector while allowing the servo to be mounted on the base. This will reduce weight on the end effector and should improve print speed and quality. Finding a good flex cable for this may be a challenge. I got the idea while thinking about how to mound a "Remote Direct Drive" to your printer. For my projects: Initially am thinking about a Raspberry Pi port. The Pi will add WiFi control and a Webcam. Secondly, converting it to use (recycle) an old 3D printer board for the kinematics. I've been hoping for a project that would allow me to recycle those electronics. Oh yeah, subscribed. Best of luck!

You sir are a genius! So ingenious and with a great mastery on this beautiful science called robotics. Thanks for sharing your knowledge and know-how, it's very noble from your part.

[@doriscampbell9775]

Yes, but with an attachment, any thing you can do with one hand it can be programed to do. Print an attachment, write the code.. Not as hard as it sounds, Arduino is a killer little processor.

[@azdmessani4544]

[@robertavraggi]

Hello, Isaac! You made an amazing robot! Please, does the HJ S3315D servo have a control angle of 180 or 270 degrees?

[@isaac879]

Thanks! The servos only have a 180 degree range.

[@wellingtonsantos7826]

Hi Isaac, thanks for sharing this with us. One question, the delta robot controller code is to run on the arduino ide?

[@peterrizk4915]

Great implementation! I wanted to do a similar delta robot since there is a lockdown. Could you please reference the book where you got the inverse kinematics for this mechanism or the schematic of your particular robot so I can follow the equations in your code?

[@isaac879]

Thank you! I derived the inverse kinematics myself so there is no book I can reference although I'm sure there must be some around. On the GitHub repository for the delta robot I have included 2 pictures of what all the variables in the inverse kinematic functions relate to on the physical robot which will hopefully help you understand it. It's basically just a load of trigonometry to calculate all the required angles.

[@peterrizk4915]

@@isaac879 thank you very much for the reply, i realised that there were pictures with the file and understood the kinematics. I admire your trigonometric approach since it shows a better understanding of the kinematics compared to searching for a ready made formula. Thank you very much and keep up the good work!

Subscribed. Thanks for making such detailed video about delta robot. It helps a lot. Have you tested it on any simulation software before making hardware one?

[@isaac879]

Thanks for subscribing and I'm glad the video was helpful. No, i didn't create any simulations first. I did model it in Autodesk Inventor and create an assembly model so I could check everything fitted and moved correctly first though.

[@tedgerahedron]

Wow it's just like Nick Seward's Simpson. Do you think it works better without the pulleys?

[@weirdsciencetv4999]

I like this guy. Sweet Delta! Subscribed!

[@tiagotiagot]

Maybe add a 3-axis accelerometer to the end-effector and use the data to tweak the position of the servos to fight the wobbliness?

[@tiantian329]

As a person who comes from the 3d printing community, I’m curious if you could attach a 3d printer hotend to it and have it run like a normal delta-style printer

[@isaac879]

Unfortunately it's not accurate enough for 3D printing. The servos just don't have a high enough resolution to get submillimeter results...

[@tiantian329]

I’m wondering if you could replace the servos with NEMA 17 steppers, which are the standard for 3d printing. You’d also have to write the firmware code yourself though, cause Marlin and Repetier can only run on normal 3d printers.

[@deveshdashore5918]

@@azdmessani4544 I've just had a little play with the simulation and they don't seem to match... I've noticed that changing the "Base to floor distance (b)" doesn't seem to cause any change to their kinematics so this might be why there is a difference between my values and theirs. Without seeing the actual calculations they are performing I can't pinpoint where the issue is occurring. Obviously I have the inverse kinematics running on my robot so I'm fairly sure mine are correct (or at least one solution).

[@azdmessani4544]

@@isaac879 yeah. I think the issue is in the base referenciel but your approach is working as well.

[@V1LKA5LT]

By the way i think the movement is too jaged for your robot, you should improve it by smothing the current incoming to the stepper motors there are some ways to do that :)

[@isaac879]

I'm not actually using stepper motors, I'm using servos. Unfortunately they aren't the most accurate so the movements are a little jerky at times although it is fairly accurate down to a few millimeters. I would love to build a stepper driven one as it could be way more precise!

[@V1LKA5LT]

What laser cutter were you using? can you make a video about that, is is made with arduino uno too? what is max laser power, and did you cut it in one thing? how actually you did that? what programs and everything you were using and how using to do that? could be really usefull, have laser myself, but don't use it becouse there is no reliable ant fast working software for it that i could found....

[@isaac879]

The laster I used is an EleksLaser-A3 Pro 2500mW. I'm currently using it with GRBL and LaserWeb4. I normally use Inkscape to design SVG file that I then use to engrave/cut. I'm have a video about the machine and what you can do with it but that is from before I changed to GRBL/LaserWeb: kzbin.info/www/bejne/h56aiYRjpLyUhJY

Hi, How to use a terminal program. ? What kind of program do you use for this? The film shows the program you are using, what is the program?

[@isaac879]

Hi there, I wrote the console application in C++ using Visual Studio 2015. The C++ source file is available on my GitHub: github.com/isaac879/Delta-Robot/blob/master/Delta%20Robot%20Controller/main.cpp Before you compile the code you will need to set the com port to the correct one for your Arduino. Once it is compiled, you can just run the program and then it will wait for certain key presses or mouse movements and send the appropriate command to the robot. The console application isn't really an ideal solution as I would prefer to have a proper GUI but I needed to get it working quickly and didn't have time to create one...

There are a lot of Android apps that allow serial communication with it, just search the app store. When connected to a pc it acts just like the USB connection and uses a com port so you can send/receive data via the Arduino IDE serial monitor or I have written a terminal program to control it (source code is on my GitHub repository).

Is the only way to control it with Arduino?? I’m really interested in building a delta robot but don’t know how to control it

[@isaac879]

This one was designed with an Arduino so all circuits and code would only work with Arudino. Ultimately you could replace the Arduino with any microcontroller that can drive servos if you wanted though.

[@tat2joeelliott]

But how do you get it to move all 3 axis when say you just want to go linear but you have 3 axis? One has to be z right?

[@isaac879]

@@tat2joeelliott Ah Ok the concept you are talking about is called "inverse kinematics". Basically for end effector coordinates given in x, y, z you can calculate the required servo angles using trigonometry/maths. To move in straight lines you can just interpolate points between the current position and target position then give each point to the inverse kinematics to calculate the servo angles required to move it through each of the interpolated points on the line.
