I just found your channel. I have been self learning programing for 6 years now as a hobby. I have played with ROS and Arduinos. I want to thank you for educating through your channel. I know it is going to be a great resource for my projects. Please keep making these videos.
Hey, I just wiped my Chromebook and switched to Ubuntu to follow this series! Only have 30GB storage to spare. Hope its enough for ROS , Kinetics etc.. Learning all the time..
it should be enough. ROS can be tough in the beginning... only because there are a lot of possibilities. once you've embraced the logics, it becomes much simpler
Hello, Great video, I am actually trying to implement this using a hcsr04, and using an stm32 nucleo and Arduino IDE. I am gettting the messages(an array of 90, 1 measurement every 2 degrees) , tf is fine, but not able to see the plot on rviz. Do u have any suggestions Thank you
It is a great video and you have used tf mini plus lidar rasperrypi ros to laser scan.I would like to have python code of tfmini plus lidar to find distance between lidar and object. I run tfmini.py file using tfmini plus to find distance, but it comes with error.
Hi Tiziano, I've tried running this as well as multiple other of my python programs on my raspberry pi for my Lidar sensor and nothing seems to function ever, the error I seem to get is inappropriate ioctl for device, I was just wondering if you could help
Hello Tiziano! First of all, amazing tutorial, I really loved it. I'd like to ask one question though. Can we do the same thing by replacing the TFmini lidar with an IR sensor like the SHARP sensor? And also, would you recommend replacing the servo motor with a DC motor to get a 360° map?
Dc motor and encoder it's surely the way to go. A servo is neither fast nor accurate. The video was just an introduction and an example. Sonars, yes, they can work as well. As a matter of fact it depends on your application. If you need a simple obstacle avoidance (as I did in the video before with sonars) or SLAM (as in the next video). Keep in mind that sonars are slow, very slow
Huge thanks. But we have a problem. when laserbeam does not return back, the lidar-hokuyo yvt-35lx does not show it; We want that the lidar should show sth weird value or 0 when the laser beam does not return the sensor. What do you think about that?
@@prandtlmayer huge thanks! May i get your contact for instance, email or sth else to ask sth if i have any difficulty on that? It would be a great chance for me to make connection with you.
Not really this one, a servo does not provide for a good enough angular accuracy. Either you change the servo for a stepper motor or you include a potentiometer and directly measure the angle. Then yes, you basically have a lidar
