Python Project | Forward and Inverse Kinematics with 3 DOF Planar Robot

[@chaitanyasutar4252]

Wow.! Thank you man...This I always wanted..This is the Most fundamental practical demonstration for understanding

[@muhammadsyazwan4974]

Super cool project! Complicated topics but it was done in a very simple and fun way!

[@조수완-r7y]

Hello, I'm a student studying robotics. If you look at the video, the Arduino code has A, B, C, and D, does it work only with A code?

[@Game.of.thrones.714]

i liked the vid. but i have some doubts where can i get the solution? could you please help me in it?

[@navidam4003]

Can you please explain how you calculated wx = px - a4*cos(phi) wy = py - a4*sin(phi) equations....will be very much helpful if you explain the equation part

[@chayanchakraborty9966]

What is code and Blam,, difference plz

[@GM-sn2vg]

why do you have 6 lengths values for your forward kinematics???

[@jadenbenton4472]

ong

[@jadenbenton4472]

I figured it out. Think of the original 3 distances you have as the hypoteneuse of a triangle. These three distances must be broken down into their x and y components respectively, sqrt(x^2+y^2) = h( one of your original lengths). Robotics 1 U1 (Kinematics) S5 (HTM) P2 (HTM by Denavit Hartenberg) explains it best in my opinion.

Orders whiteboard, ends up drawing coords himself :) just print lines on paper and glue on paper on a mounting surface :)

[@CooperDuper3000]

i just want to inform you that you have a little mistake in your arduino code. For Example @04:59 you can see that you have specified pos_two = 86.4 but you declared pos_two as an int that means you can not store float values inside of an int variable. What you will get instead is that 86.4 will mit truncated to just 86 and stored as an int variable inside pos_two. If you do that a lot inside your project you will get a heck lot of inperfektions of your positioning. Solution: Use float or double instead of int for any floatingpoint number you want to store inside an variable. *Cheers*

I am a Korean developer. Your video was very helpful.

[@hassanismail6120]

Hello, I want to make 6 DOF robotic arm. can't we run the motors directly from python? From where i get the 6 DOF robotic arm ik equations?

[@songtingyu626]

hello, im doing a project on a 4 dof robotic arm but i dont really know how to use inverse kinematics to control my arm to move to a specific location can you help me with it? appreciate it.

[@GaryMcKinnonUFO]

Very cool indeed, thanks for sharing.

[@max.s_tech]

Could somebody translate this python code to c++ code? Please it would be sooo helpfull

[@himanshkumarsahu6473]

arduino code plzz

[@mysticalsoulqc]

Thank you for intro, i would like to connect my gt2560 prussa that i converted in a robotic arm to blender. would you be kind and share a script for that. i am new at this. thank you, i will open source what i do also. thank you

[@harisshs3461]

Can anyone say, how to calculate inverse kinematics for robotic arm (3dof) L1 =4.8inch , L2=4.8inch , L3=5inch? How do I determine the value of phi ?

[@kaylaschuchalter5788]

great project! what is the differance in equations of inverse kinimatics if i want elbow up??

[@darkrasen]

Awesome project, thank you so much for sharing the code!

[@권남수-o3v]

It's very very helpful. Thank you sir.

[@robonxt]

Nice! Is there an code for the Arduino for 3 DOF? It's not in the github repo, and I'm not sure how to modify your 2 DOF program. Thanks!

[@ayeleyorr6609]

plz can i get the arduno code

[@erentekin227]

hello sir, I am designing a 4 axis robot arm for my university project. What is required of me in my project is to move my robot arm lineary in x,y,z axes with 3 potentiometers. I need your help with software. I would be very happy if you could help.

[@QRobotix]

what motors are you using?

[@erentekin227]

Servo motors

[@aubbdulhannanthanamas3173]

How much should be included in the configuration corner? thank you.

[@kotai2003]

Very nice instruction. Thanks a lot.

[@ngocsangao5536]

Love your project. Can you send me ardruino code and your connecting from robot to ardruino

[@QRobotix]

Hi the code is in the description. You can check out my dxl playlist for connections

[@kridsadahaengphit8514]

if we need control degree by gui. how to write code interrup?

[@QRobotix]

Maybe use pythons tkinter library?

[@nttn_mare]

I built a 5 Dof Robotic Arm and I need your help. Can I sent you a picture of it? I dont know how to calculate the inverse kinematic of it

[@QRobotix]

Do you have a video? Share me the link

@@QRobotix Are you able to help me? Would appreciate it :) I am only 18 and i tried to code the inverse kinematics for the robotic arm. But I failed.

[@benjaminmclaws3477]

What method do you use for inverse kinematics? Or does your program just use trigonometry to solve for the motors positions?

[@QRobotix]

Yes the inverse kinematics is derived from trigonometry

[@5621346]

nice project!

[@cengiztezel4576]

its looking amazing! can you add PID control on python ?

[@QRobotix]

Yeah you can if you want to.

[@varunwalimbe3468]

I am making a 3DOF Robotic Arm that can pick and place objects. I am not able to figure out inverse kinematics equations by myself as there are no resources at all. Yours Is the only video which is practical and I have understood so far. Can you please make a video on inverse kinematics including Z axis also ? This is because for pick and place robotic arm Height is not fixed.. So Z axis will change.will you please make it? I am really confused how to figure out that phi angle

[@QRobotix]

So you are building an RRR articulate robot?

[@varunwalimbe3468]

Yes... Can i send you the picture of my robot on your email if you don't mind? Can you just take a look at it?

[@QRobotix]

@@varunwalimbe3468 yup I'll take a look at it
