Would love to see a detailed explanation of the inverse kinematic model because I need it for my robot! Nice video and thanks for the time and effort you put into the whole repository!
Luckily, I found your channel...Huge robotic knowledge which can't be found on other channels. Wish you will be soon gain more subscribers...Greatings from Vietnam
Wow that is an Amazing Guide to Build the Robot! Every Time you Upload One of your Videos I'm verry Happy. It's nice to hear there are optional stepper drivers to Reduce the total costs of this Project. 👍 Can't wait to Build one! And as mentioned: thank you for your efforts to Make such a great Open Source Project 👍👍
You are the hobby king. No one else. Great video, I appreciate the your time documenting your work on github. Also, I'm learning from every video. Mechanical designs are complex and inspiring. Please keep up the fantastic work, its awesome. Thanks!
That is absolutely fantastic! You have devoted so much time to this. Thank you so much. If I don't build your design (it needs a name), it will not be because you have not provided everything necessary.
Just came across your channel and like the Robot you are building. I probably won't build one for myself, but probably will never get around to do it. Anyways, I am looking forward to see you progress with this build.
Con tu gran conocimiento y experiencia quisiera preguntarte si sería factible la construcción de este brazo robótico utilizando una CNC en lugar de fabricar las piezas con impresora 3D?
Long shot on a response but do you have a recommendation on how to print the large chunky part of axis 2? I’m having trouble with internal supports generating in places I can’t remove them but the print needs them to complete. Thanks for any help or direction!
i absolutely love this project, the arm looks artistic, its very skillfully designed. What do you plan to do with it? you should put a hotend on the end effector to make it a 3d printer
It would be a nice 3D printer! It should be able to print complicated parts without any support. I thought about this, but it would be difficult to write a program for this. Basically it should be a slicer for 5 Degrees-of-Freedom 3D printer. Maybe I will try to do this, but I am not sure to be capable to program this.
@@Skyentific It really would if used with all 5 axis, but even as a 3 axis machine (easier to code firmware) it would be incredible and could print objects that are many times it size. Id really like to see where it goes, personally. Ive been designing a few printers that use scara coordinate positioning, similar to something called the reprap helios. (google that by the way, its very interesting, even if not quite as cool as your project lol.)
this is so nice desing.first part i looked nema8 3.9v .why did you choose it? was it only available then? can i use 6v or 12v version they are 5mm longer.im sure not fit errr
Hi. Thank you! Yes, the inverse kinematics is implemented in the Arduino program. The working area is around spherical with radius around 220-250mm (the precise working area depends on the end effector). The maximum reach of the centre of the last joint is 274.5mm. In the build video (Part 1) there is mechanical diagram with dimensions. I hope this will help you.
Great work. I could not have time to study your IK algorithm. Did you ensure something like trajectory planning to achieve constant velocity throughout the motion or do you only define the start and the end positions? And do you have prevention for the singularities?
What driver did you use to control the speed of the steppers with that much precision ? Mine only take rounded intergers so I cant do linear trajectory with my robot arm
I use Trinamic drivers which I control with the Arduino Mega with custom program. Thus everything is very customisable. And now everything is open source!
Ciao, complimenti per il progetto, mi ha affascinato da subito, sto terminando la stampa di tutti i pezzi, solo che trovo una grande difficoltà nel reperire tutte le cinghie, pulegge e cuscinetti necessari. Non sarebbe una cattiva idea se mettessi a disposizione un kit pronto per l'acquisto di tutte le parti meccaniche. O magari dei link diretti per l'acquisto....spero tu possa aiutarmi, complimenti ancora, Sabino.
Hi! Great project! I've just came across the ROS environment and I wanted to build from the beginning my very first robot arm. How would you suggest me to start with? I'd like to achieve your skills, but I'm wondering how could I use arduino and ROS togheter for getting the robot to work. Anyway, thank you for your professionality!
I love your project! Thank you for sharing your work. I have a question about Kinematics , in case of a robot similar to 5axismaker.com, what is the way to convert/use the robot geometry ?
Efi Kamara, thank you. I am not sure that I get your question right. 5axismaker uses Cartesian geometry (linear (prismatic) joints on perpendicular axis), the robot from this video has revolving joints connected in series. Thus it is much easier to convert Cartesian geometry, but a serial robot takes much less space. I hope this answer your question.
@@Skyentific Thank you for your reply. Your work is great. I am trying to understand your program and modify it to my robot. How can your Kinematic Diagram and geometry (on your video - ua-cam.com/video/Sgsn2CM3bjY/v-deo.html ) be translated to the one of 5axismaker - How can it be convert to Cartesian geometry?
Perfect question. The simple answer: because I don't have any experience to work with FPGA. But I will definitely consider it. Thank you for this idea!
Please leave your comments! Any comment will help me to promote this channel.

Just google it. This is really nice SCARA robot! Thank you for this link!
I see huge potential for these types of projects@@Skyentific

Please share the explanation of the control software>>
I hope you can teach us who to control the robotic arm using ROS too...
best of luck...
Thank you. I will definitely do this. I never used ROS, but I would like to learn. So video with the ROS is in my plan too.
Hi, This work is amazing!! Did you implemente the inverse kinematics? And the size of the working area?
Hi. Thank you! Yes, the inverse kinematics is implemented in the Arduino program. The working area is around spherical with radius around 220-250mm (the precise working area depends on the end effector). The maximum reach of the centre of the last joint is 274.5mm.

Great work. I could not have time to study your IK algorithm. Did you ensure something like trajectory planning to achieve constant velocity throughout the motion or do you only define the start and the end positions? And do you have prevention for the singularities?
Hello. Why is there no usage of any limit switches?
I start robot arm always from the same position, which is home position for robot. So I don’t really need to home it.
How much is the backlash? Can I use it for pick and place SMD fine pitch components?
What driver did you use to control the speed of the steppers with that much precision ? Mine only take rounded intergers so I cant do linear trajectory with my robot arm
I use Trinamic drivers which I control with the Arduino Mega with custom program. Thus everything is very customisable. And now everything is open source!
Amazing work!
Amazing work you are doing. Is there a possibility that you can send me a whole kit with all the required parts?

Where can I get the Belts and Pulleys (GT2) in Europe? I only find suppliers in the US
Awesome , where did you get the axis tubes made ?? The ones that fit with the bearings ? Axis 1,2 and 3 ... Thanks
I want to know too! I asked somebody can custome these tubes. But it is extremely expensive. Did you solve it? Thanks!
What is the infill density of 3d printed parts?
How come you didnt use any encoders? dont you need absolute encoders so the robot can start in any position?
How to connect and control the robot with ROBODK? I've built the robot, but I can't program it.
hello dear . how much is the payload of the robot ?
Fantastic job!! Thank you
I love your project!

why dont use fpga as dexter ?
Perfect question. The simple answer: because I don't have any experience to work with FPGA. But I will definitely consider it. Thank you for this idea!
Awesome!
MrWachowsky, thank you very much!
Great work
thank you a lot, i am a beginner
