OMNi is a DIY open-source robotic platform built on the ROS2 framework. OMNi ultilizies a LiDAR scanner, interial measurement unit, and motor encoders to autonomously navigate indoor environments using a SLAM algorithm (Simulatenous Localization And Mapping).
Components I frequently use:
Arduino Uno: amzn.to/30WTweL
Raspberry Pi: amzn.to/3qI5ouf
Arduino Nano: amzn.to/3mwClIy

Waw, this is truely an amazing video, one of the best I've seen on RUclips... and believe me, I've seen many !

[@WillDonaldson]

Thanks!

[@Al-kz2cf]

That's amazing! You should try adding 4 cameras to get 360 footage like what Mark Rober did in his glitterbomb videos.

[@WIZURAI-AGV]

Amazing work!

[@surfacta]

3:58 theres actually a minimum distance of data points setting in the hector slam launch file, so its a pretty simple fix

[@constellations8572]

Amazing project! How did you get started in robotics and building? Any books or courses you recommend?

[@WillDonaldson]

Got into it from watching too many scifi movies! There's a ton of great resources online (I mostly learnt online myself), if you want to take an academic approach one resource that stands out is MIT Opencourseware. You could do an entire degree for free. Lots of content, my personal favourite is the Underactuated Robotics course - it is fairly advanced (grad level), but I recommend everyone watch the first lecture in the series. It isn't super technical (and the math cna be ignored), it is super inspiring seeing what can be done.
That all being said, I don't recommend the academic route often, I think it is best to find a project that inspires you (and will keep you motivated) and then learn what you need to along the way as you solve problems that arise

Hi sir ,
I wnat ti implement a CAN communication protocols to control robots .
I am not getting any guidance please help me I am also struggling to find the Motor driver for DC motor which is compatible with CAN.
Also how should I start to work with CAN??
PLEASE REPLY.

[@mdandry]

Thanks for the video log. 🙌🏻
I am building an omniwheel robot as well and what you’re doing is very helpful, thank you. I am amateur in this field and this is my 2nd wheeled robot. Would you ever be available to chat with about the projects?

[@adamsoileau4804]

That’s super sick! Have you considered incorporating computer vision?

[@WillDonaldson]

It is a feature I'm considering adding to the robot. It would resolve the LiDAR's planar field of view issue, but is computationally heavy. Alternatively, I might at add a different LiDAR sensor that generates a point cloud. Check back in on future videos to see what we go!

[@arjungk5357]

Hey! Can I know how to set the minimum scanning distance of the lidar? It would be great if someone replies. Thank you in advance.

[@skywalker8568]

hi sir can we get the code?

[@tehtron]

Have you tried comma body?

[@taylan_arslan]

Dude, ı am trying to do something similar for a competition but on a tighter budget... Good luck
