Great video. No nonsense with no extraneous information. Very motivating as well. Something I will aspire to build. Possibly, in the initial phase will try to create a simulation. Thanks very much for creating this excellent video

thats a really good demo. i like how you went through all the steps. i am just starting my ros learning journey

I'm very happy to give us informative video and support in ROS.

That's almost some best precession. Amazing work.

From zero to hero!!! This is an amazing and complete tutorial for anyone new to robotics! Thanks for your time and effort putting this together! I hope you provide another project based on a robot navigation with only a depth camera.

wonderful explanation as always!!! Thank you!!!

Great video sir, I have been researching for a similar project, so far this is one of the best informative sources I found.

Thanks again, very informative and easy to follow.

Thank you for Video! Priceless for me, working on similar project, but with only Stereo Cam (no Lidar) mounted on Quad3DOF.

Job well done and thanks for sharing peace and love from San Diego CA!

Thank you very much. This is what I need!

Incredible work!

Great demo. Thank you for sharing.

thank you for this awesome video i learned a lot and will be using lidar to our thesis

This was really much informative video indeed 👍👍 .. i am looking forward for more such videos

I really like your work good job and thank you for sharing info.

very good built and performance

Thanks for the informative video

Great work, nice video

Awesome 👍

Amazing!

So noice thanks for sharing

Thank you sir!

Brother you explained great,but could not grasp all of it. Could you make another video on navigation stack and explain it from a beginner point of view please. Thank for your efforts

Thanks you brother

Hi Greate Video , I am your fan

Great work, kindly share the complete wire connection diagram.

Great video. I have been looking at getting a Vector Robot to play with the AI but finding it may not be up to speed. I'm simply looking for something like a Vector robot that can explore the area, charge itself, and more where the AI comes in, be able to collect small objects and take it home. For this why I picked the vector since the base design is perfect yet with too many limitations. A perfect robotic mouse which I am so shocked I can't find anything close to it.

Thts great tnk u

Good!!!

Sir please provide a detailed tutorial on how you implemented this with ROS along with hardware integartion with jetson nano, it will be great help to us for understanding autonomous navigation concepts.

Such an excellent video and good explanation. Actually at the moment I'm working on the similar project which it might help me a lot if you can share the schematic connection and the list of components that has been used. is that possible to get it?

Thanks for the video, very nice. but can you provide a connection sketch ?

Amazing video!! Thanks for sharing. I am little confused about the lower level PID controllers that you wrote for the individual motors. Why did you choose to implement the controllers using Arduino library? You could have use ros_control package to do that. Is there any specific reason?

the first video I saw in my life that have 0 dislikes

Great video, I'd like to learn ROS from scratch and i'm currently working on these types of projects, please help me out regarding ROS, Lidars, Autonomous Navigations

Hi brou. Gerat Work!!!!!!!!!!!!!. What communication protocol did you use? :D

Hi, great video. Helped me a lot. The next thing I want to do is to publish the directions like turn right, turn left. Could you please help me with that? Thank you hoping for A reply

awesome videoo thanks, why you use 2 seperate arduino nano istead of just one ?

Awesome videos man congratulations. Could you create one explaining the ROS hardware Interface?

great video but can you explain to me why two specific nano?

Hello, in which part are you connecting the encoder data with the Odom node?

Hello Sir, awesome project. I have a question. Can I use a Raspberry Pi instead of a NVIDIA Jetson Nano? My budget is very limited but I loved the project.

Hi sir , your tutorials are amazing. But Iam getting confused with one topic i.e interfacing the urdf model with the real robot hardware which I have. Can u please guide me to do this??I have a urdf model working separately and a real robot working separately.

may i know if register the jointLimitsHandle in the h/w interface and the joint_limits.yaml are required since velocity and acceleration limits are already specified in controllers.yaml?

Will you please tell me how you tuned the PID values of your DC motors?

Please anyone answer me,after completing the project robot still needs wifi to function the Ros or works offline after?

Any particular reason why two separate Arduino for each motor? And you are publishing only wheel velocities from Arduino and publish /odom on Jetson nano? There was no mention of an IMU... how did you manage to get the encoders very accurate? very good PID tuning I suppose? or are you using laser scan matching and fuse it with wheel odometry...

Hi, why do you connect the jetsons pins to arduino nanos. Is it possible to connect the motors directly to the jetson board?

Bro why using arduino nano, can't we sent pwm signal to driver from the jetson Nano..?

Does the LiDAR Autonomous Self-driving car needs to have training on localization for it to work? This would be my thesis. Hoping I would receive a reply from you.

Thank you very much. I implemented your project with some modifications. It is running very well. Only issue is drift in odometry while robot rotates. I used two arduino m0 samd21 instead of arduino nano. I used as5600 absolute encoders instead of incremental ones with i2c communication. In samd21 there are more than one i2c ports. I don’t understand why you use this code in Robot_hardware_interface_node.cpp if(left_prev_cmd!=velocity) { result = left_motor.writeData(wbuff,2); //ROS_INFO("Writen successfully result=%d", result); left_prev_cmd=velocity; } I couldnot run without cancel if part. Can you explain why you dont send speed value to arduino if it is same as previous one? Another issue in arduino part, i can not understand how you send negative speed value to arduino from ros. I did some change to run it. I modified code as, 0 255 full speed forward. 255 255 full speed backward. How did you design it? Thanks for your answer

Hey, I recently decided to switch to ROS Noetic in my new OS of Ubuntu 20.04. Do you think your repo can be functional in the new versions of ROS?

Hi Good Work How to increase the speed of robot? Thanks

Hello sir do you have a step by step of how to install the needed ros packages im a newbie plsss thanks you

Are you also including sensor noise in it and filtering it. If not then can you help me out how to include it and then use a filter like kalman to show how the noise is reduced

Can you please make a video on how to add landmarks in this map?

Hi! Amazing project! I'm building something like that but I want to know if the encoders are 100% necessary?

what are the specifications of the battery which you used ?

How to use the navigation stack with the Pioneer robot (with rosary) and the rplidar a3 sensor (Hector Slam or Gmapping library) Hey, My question is how to use the ros Navigation Stack library to perform autonomous navigation on the pioneer robot that I am using the rosaria library for control, I am also using the rplidar_03 sensor with the hector slam library in the project. If anyone can help me

Is it possible then to write a program that divides the map into car parking spots and provides the robot with a paint unit and the robot paints the specified places

hi, i want to run same navigation on arduino + raspberry + ros my map is saved , kindly help me for autonomous navigation (hardware interface node)

any alternatives for the encoder motor?

hi why you use 2 individual arduino for motor

You have a link to those motors for those of us in the US?

Hi. Amazing tutorial. I have a small doubt. How did you run the Jetson Nano without a cable connected to the laptop for Display. I presume you used VNC for teleop_twist_keyboard. Can I use a wifi module on the Jetson and connect it to the same wifi network as VNC? Thanks

Is there a playlist for building this from scratch?

Hi! How do I get the value 1856.0 of my motor?

How to get the mapping.launch file? Is it related to the robot shape? Thanks.

I'am a newbie I wonder why this project use 2 power (portable charger + battery pin bonus) can you explain it, pls

Thank for this great video, but I don’t understand your arduino codes? How’s it relative to ROS?

Can you explain the structure of the files that are useful and along with the components? And also, is it possible to use RPi4 instead of Jetson Nano?

good day sir...I just want to ask where can I download the software?

On running back your package I found issue with" Could not read from i2c slave 0x8". Although my jetson is detecting the MCU with same adress. What am I missing?

what is the use of seq_of_goals.py file use?

Great video and explanation, but I am still wondering how there is no ROS topics being subscribed by the Arduino Nano. Am I missing something?

pls send the buying link of the above components used.

Hello i made the robot using your package with a different body, but i don't know why, the robot is not moving while using teleop

Pleas ,can you give me the link to load the backage form terminal

Hi )) Why if i start only move_base node my robot all work, move_base subscribe on /scan But if i start amcl with move_base amcl subscriber on /scan, but move_base not subscribe on /scan, and robot dos not work Pls helm me please)

Is this support noetic

could you please share the circuit diagram

how can I download the ROS software. is it open source?

2gb kit is enough to make this bot?

very informative video as always ! . Can you please provide some sort of contact details

Have u done imu integration for odom?

Hello. Is it possible to use octomap real time instead of building a map a priori?

What application did you used to create 3d parts?

Did you use VNC to remote the screen of jetson nano?

i am facing error " could not read from I2C Slave "

Your robot has two different arduino. What is the reason of this, can i use a single arduino?

what type of DC motors used in this....? can you share Specifications

Is ROS Kinetic valid even now??

Hello bro why are you not explain about yml file

I cannot connect I2C between 2 arduino nano with jetson nano. I have error address 09. Hope you can help with the method of connecting hardware and software?

How did you connect robot and laptop wirelessly, can you do a video on that?

hello sir can you help me to doing this project . i need help

Hi! I wondering with what did you supply the motors and the jetson nano?

Hi sir, Iam a robotics student of 2 na year Iam very much interested in learning slam and navigation , I know the basics of ros and I even have a differential drive robot working with teleop keyboard , if u are free will u please teach me slam and navigation sir , Iam ready to pay you sir

does this work on ROS melodic ? , if not which ROS should i install to do this project .... please help me anyone
