my controller won't subscribe to /cmd_vel idk what's up

Gracias, genio

At about 5.30, How would the odom frame relate to another vehicle, say a flying drone? Since it does not have a pose estimate from the rotation of the wheels? please note: I am using ardupilot and the drone from iq_sim. so there is a connection with /mavros I am having some trouble localizing because i do not have the transform from odom to base_footprint but i do have the transform for map to base_footprint. would really appreciate if anyone can help me understand this. cheers!

I was wondering how to run Jest tests inside docker container so that VSCode extension shows result Visual Studio Code Dev Containers is an answer )

thanks a lot , we have been stuck on this for weeks, and now it works

So I'm having a bit of confusion here...so after "sudo apt install ros-jazzy-rplidar-ros" it installs fine...but it's in an opt directory. Then when I go and read official documentation, it's telling me to install the RPLIDAR package to the robot_ws/src directory. What's the discrepancy here? Are these different things for different purposes?

Hello. First of all, thanks a lot for these tutorials. However, my controller_manager is not available and I’m getting a parsing error with my_controllers.yaml. I’ve checked the files multiple times and they’re identical, but for some reason it doesn’t work for me.

For anyone wondering the right command now is : pyserial-miniterm -e /dev/tty* , he explained this in the last video of the serie😉😉

is it the same in ROS2 ?

🔥🔥

I'm getting anxiety by looking at your workflow - constantly touching mouse :D

Info is pure gold. Thank you sir

Is it possible to do the point cloud step for gazebo & rviz with intel's realsense D435/D415? I need to do it as a part another task.

This is absolutely perfect. I bought a second Steam Deck when the OLED came out. I was about to give my old Steam Deck away, but when I decided to go on the journey of making an AMR, I decided I better hold onto it. But the main reason I was holding onto it was because of something I saw at the Boston Dynamics booth at a robotics expo and the way they control their bots. I thought it'd be amazing to do that with my bot and a Steam Deck. I was definitely not thinking of using it as the main development workstation....but installing Ubuntu on it and using it as the full workstation is an amazing prospect. I will definitely be doing this. Thank you!

My robot should have exploded or be dead by now 😭 I have put it through hell without knowing anything😭 I’m holding things closed while the power is running, using leds, lidars, multiple Raz Pis, servos, dc’s, sensors, cameras! My Bot was cooking!!!! Thank you for your video and the time you put into it! I have learned so much in a short period of time and you have saved me thousands of dollars from my ignorance throwing all my investments into one robotic project without understanding power restraints and protocols! Thank you!

my gazebo world doesnt wanna save. the world file exists, as soon as i open it its just blank with the bot. I'm following the exact same steps

How feasible do you think running SLAM directly on a Pi 5 would be now with the new Jazzy/Ubuntu 22.04 combo?

How good is rosboard as an alternative for foxglove?

Sir i need your help Please guide me. When i enter miniterm -e /dev/ttyUSB0 57600 That command in terminal Terminal show miniterm command not found

can i use cytron motor driver ?

please i use conda ros2 , how to add package twist_mux ?

Hello ¿Could you do a video using robot_localicalization pkg using IMU and GPS for a real robot?. Please...Your videos are greats !!!

[async_slam_toolbox_node-1] LaserRangeScan contains 455 range readings, expected 460 geting this error what should i do? thanks and regards

I'm really impressed with the quality of your videos... can tell you work really hard in the editing. your RGB and video overview with showing the compression via the frames in the video we were watching was great. Very good at general presentation as well... thanks man :) hope you have a good day today!

@articulated robotics Please do a video series on Nvidea Issac sim with ROS as now it is growing very popular and it has lot of tools especially when we are doing stuff like RL.

Is it possible to control the autonomous robot using this method?

Thanks for the great work Josh. Has anyone managed to get the map-server to publish the map to Rviz2 on Humble? I have the correct QOS settings configured, but can't identify why the map is not being received. Thanks in advance.

hi how are you getting topics automatically? I am doing everything the same ,the only difference is i am using .sdf file and not xacro(in ros-noetic). during simulation i can see the image of object shown by camera rectangle, but no topic is created in rostopic list. you are writing depth and all depth topic got created, how?

Hi, on running `rqt` in the container I get the following error: could not connect to display :0 This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb. --- Could you please help me out with this?

👏 amazing

any ideas how to change parameters for 4 wheel diff drive ?

Im enjoying your playlist while doing this, however, i cannot seem to make it work. when I run the launch program it just says robot initialized and doesn't continue any further. pls help @ArticulatedRobotics

Awesome video! Here's an Idea or a bunch of Ideas for up coming videos... I want to build a smart RV... I would want it to cook, clean, find my stuff and bring that stuff to me. I need to build a set of robotic arms that run along a track hung from the ceiling (It could fold itself up and be out of the way when not needed), I would like to use visual slam, to map and constantly update said map as it moves (obstacle avoidance, where is my cup of coffee, etc.) also has to do object recognition obviously. I have seen that using machine learning the robot ai could learn how to do tasks from watching KZbin videos using pose estimations and then using ai to find the most efficient way to preform the task and be adaptable to new problems as they arise by running simulations of said task several times before performing the task, and learn as it does the task! I'm also not sure about the best way to run this... Computation (AI) is going to need a semi-decent gaming laptop at minimum, but the robot arm is only going to require a raspberry 5 with ssd. It would essentially just run the stepper motors and sensors (pressure sensors in the grippers, cameras, etc.). Then the main brain needs to communicate with the ros in the arm to preform tasks. I would want it to all run local with a G.U.I.

I wanted to add this side note here, since it was my own question as well. In the ros2_control.xacro file: # diff_cont is the name assigned to a controller instance (chosen by us) # diff_drive_controller is the package that contains the controller plugin # DiffDriveController is the specific controller class within that package

Thanks a lot. You are saving my life)

I literally just yesterday thought I hate having to restart my containers over and over again. in some ways docker is really great, in some other it is really annoying. this fixes a lot of that

What is the reason you do the motor-control on the extra arduino, and not on the RasPi, too (with ROS)?

Is there an adaption for ROS2 Jazzy with Gazebo (maybe GZ Harmonic)?

Video is amazing, thank you so much!!!

can I use this controller in my robot that has four wheels? and what should I do to update this controller

dev container appears to break codegpt, any advise?

Did you have to use the xrce dds for it to work?

I've been trying to figure wiring my closed loops for months. Still don't get it.

The "clap" magic of adding 2nd motor is all I needed to see. I just needed to know if all motors share the same step dir Ena pins on the controller. If so, how the he'll does a signal know which motor to send to?

Bro just started spitting fire out of nowhere! 4:48 🗣🔥🔥🔥
