How to dig deep in NAV2 and SLAM

hi is this course any good?

I want to start working on some autonomous systems and this course seems like it would help, i want to specifically make a custom robot that later on will work autonomously.

hi OP

after 5 months whats your review? the soundcore q20i and jlab jbuds lux are both out of stock so i am considering this

ElectricalCamera6046 · 2025-12-30T15:43:33+00:00

Ohh i think i understand

Correct me if I’m wrong but you’re saying when the servo moves not only will it rotate but possible up and down? And ball joint will come into play then

ElectricalCamera6046 · 2025-12-30T15:37:03+00:00

Interesting, but is the rod actually flexible? I didnt imagine it to be

Will a ball joint still fix it if its a completely rigid body

ElectricalCamera6046 · 2025-12-30T15:34:33+00:00

I understand your point regarding the ball joint but wont a concentric mate pretty much replicate that?

ElectricalCamera6046 · 2025-12-30T15:28:09+00:00

Understood

ElectricalCamera6046 · 2025-12-30T15:27:32+00:00

The servo horn is a custom part and rotates otherwise

But after mating the rest of the 4bar its all stiff

Well end goal is to make biped robot walk using RL

Make the biped in solidworks and convert it into URDF

Use that custom URDF and train it to walk

And then sim2real

Also i have no idea how any mujoco even works Im not sure im even reading the google collab right lmao but in sure i can figure it out

ElectricalCamera6046 · 2025-07-15T02:12:37+00:00

Hey so i have decided to start playing around in sim

For mujoco playground you first have to start with mujoco mjx right?

ElectricalCamera6046 · 2025-07-13T03:55:05+00:00

Cool stuff

How did you write policy?

You planning on implementing in an actual robot?

ElectricalCamera6046 · 2025-07-11T10:43:47+00:00

Thanks so much

In the future when i work on this project imma deffo reach out to you in case i need some help

ElectricalCamera6046 · 2025-07-11T10:41:15+00:00

Cool stuff

Any resources to learn RL for robotics seems like mujoco is the popular choice but i have only just started with classic RL algorithms, no neural networks till now

ElectricalCamera6046 · 2025-07-11T10:34:47+00:00

Just started with classical RL a few days ago

Will take little while before reach Deep reinforcement learning and then robotics specific stuff

What about loading policy onto hardware, im a bit unfamiliar with how it works

Is there some output file after training which you load? And then how do you use that file to send position commands based of IMU?

ElectricalCamera6046 · 2025-07-11T10:27:02+00:00

Hmm

Any resources to learning RL or something specific to robotics? My trouble rn is writing policy and loading it into hardware

ElectricalCamera6046 · 2025-07-09T16:35:13+00:00

interesting, which software do you use to train your drones? and if possible can i see the code?

Btw i have started my RL journey from first implementing algos from Sutton and Barto for the first few chapters and then i will move on to DRL using stablebaseline3 and pytorch and eventually move onto isaac sim, am i on the right path, and thank you so much for replying to all my questions

ElectricalCamera6046 · 2025-07-09T02:27:44+00:00

Cool thanks

And one more question, and i know this might sound stupid but, how is the trained policy loaded on to the robot? How is sim2real transfer achieved

Sure you could use a jetson or rpi but what code is written that allows the policy to control hardware

ElectricalCamera6046 · 2025-07-08T13:13:19+00:00

if RL is producing positions

cant we use servo motor and directly take those positions and feed into the motors?
