Easy inverse kinematics for robot arms

How to make robot arms move in straight lines.
Easy inverse kinematics using high school level maths and an Arduino.

Please let me know if you make this or use the techniques yourself.

Thanks for the tutorial! For those wondering how to solve for arms with different lengths, you can use Law of Cosines to find the angles with only the sides of the triangles. Just thought of sharing this here because I faced the same problem too😄

i cannot thank you enough for your effort in explaining such difficult concepts with ease a sense of assurance that one can easily learn if taught properly . thank you for being a good member of the fellow robotics community .

I loved how you explained the trigonometry! Honestly, no matter that may master's degree is in Robotics, i really enjoyed how you explained all the stuff here! Good Job!

Thanks for such simplified video. Frist time I understood the math to a good level 😊

Really easy inverse kinematics for robots- As maker I have implemented these guidelines and equations sending coordinates by bluetooth, from a python code, and let me say it works awesome. You developed all this stuff as easy as possible. Thanks a lot, if I have time I will explain this in spanish. Please do not stop to work in new ideas and videos, we need people as you as subject matter expert, but simplyfing the knowledge.

Best video about inverse kinematics I have seen so far, very simple explanation and straight to a point

This is an excellent video. I built the HowToMechatronics SCARA robot arm (4 DOF), using 4 stepper motors and one servo motor.(for end effector). The designer also provided a GUI made with Processing language. The entire robot uses an Arduino UNO. The build went well and everything works, but now the fun part of teaching the robot arm to do stuff. The GUI shows forward and inverse kinematics and I'm trying to develop a system for teaching it to pick up wood blocks to spell a name. Your video certainly helped explain the Inverse Kinematics. Mechatronics worked out all the equations for the user, but didn't really describe how to use either to move the arm where the user wants it. (I can jog to a position and save the value, so I'm assuming this does the trick. The video was very well explained and you are very articulate. And you pronounced phi as "feye", not "fee" as some do. Small things matter.

excellent.
for simple robots/arms with no object collision or difficult to address hierarchy, i guess you need nothing more than this.

Excellent explanation! Your channel deserves a lot more subscribers.

Another great video like the first arm you built. I will probably steal your code as you've done all the hard work already. Thanks for sharing the math involved in this project.

Man you made this look soo simple, its awesome!
I had to write up a self investigation for a topic I was interested in while I was in year 10, and I investigated inverse kinematics and I dove right into all the matrices & stuff and I was only able to get a 2D one working. Awesome stuff!

Excellent video, very well explained. Your a genius, I wish I had a math teacher with this kind of skills when I was younger...

[TheRealStructurer]

Very well explained 👍🏼 Have been thinking for a small robotics arm for desktop videos and this has inspired me to get going. Thanks for sharing 👍🏼

[silvio]

Thank you so much for this video, it's the best inverse kinematic video explanation that I've seen, thanks to you I've understand :)

[STEAMfromScratch]

I love this. You're a genius at explaining inverse kinematics. If this was my first time, I would have absorbed your lesson instantly. Nicely done!

[Ozzymand]

i am making a robotic arm and controlling it with IK for my thesis, this video is a huge help

[scprotz]

Very nicely done. Easy to follow and understand. Great job.

[jack_sparrow]

Thank you very much. I am planning on making a 4 leg Arduino spider bot with 8 servos. This will help me a lot. need to brush up basics of Trigonometry though I hated it in school but seems interesting now as I have a purpose to learn it.
Thanks a lot after hours of watching YouTube i got to know this thing is called as kinematics and after few hours I got your video.☺️

[LazyDogWoodshed]

Great vid, loved the simple explanation

[Yenrabbit]

What a useful video series and design! Thank you for sharing, this is outstanding
