You forgot to add exit holes for the warm air pushed through the case by the fan. :-)

[@ankur261995]

Can you also do a video on Kinematics for the arm using ROS?

[@Magnetic999]

@@AndersJackson There are holes, watch it again :)

[@AndersJackson]

@@Magnetic999 well, they are not that large. And depend on those small holes for the power supply. Yes they are, yes they are better than nothing... ;-)

Always enjoy your videos, they show some interesting aspects of robotics every time!

[@Skyentific]

Thank you a lot for always inspiring comments! It really helps to continue doing this.

[@neversaynever5157]

Great video , thats a very neat setup youve created !! . I look forward to seeing the next stage, Thanks

[@AlxM96]

Jetson Nano and Realsense D435i? Something tells me you want to mess around with neural networks, and I couldn't be more excited! You should try using PPO, I'd love to see that.

[@jonwatte4293]

Also, I love how you say "ada froo eet" :-)

[@lorandnagy3277]

Another very informative/interesting robotics video.Great work!

[@Skyentific]

Thank you!

[@shecterelectric432]

Nice work my friend. I really liked how you put all toguether, very organized.

[@jonwatte4293]

Well prepared as always! You should probably print some strain relief for that mains cable, though!

[@W0lfbaneShikaisc00l]

Trying not to crack up cos of the accent "I found this small touchpad instead of mouse" Oh boy. You're making this difficult. Really interesting, I'll have to look into making my own version later on.

[@kirilchi]

Interesting as always, never heard of this camera, it looks cool. Also very nice casing for Nano. I have both Google TPU and Jetson Nano, I think Google might be a little faster, but I did not try them yet :)

[@Skyentific]

Thank you! I was hesitating to buy JetsonNano or Google TPU. And finally decided for Jetson Nano. Because I can install PyTorch and TensorFlow. For google TPU I think it is only compatible with TensorFlow lite.

A couple ideas I had while watching this video that may be horrible, maybe not? Regarding the speakers, maybe print some new risers/spacers that have a ramp along the sides to reflect the sound out the sides the way some older laptops and portable handheld TVs did? If you look online at patterns for "iPhone passive amplifier stand" type projects, they use the same idea and add a cone for amplification. Which, now that I think about it, you could print as well, if you desired more volume. On the fan: For speed control, look for some older style PC fan controls like the ones from the early 2000s that came with "temperature sensor speed control" built in. Basically they had leads with thermistors that you could squeeze in between the fins of a heat sink, or just place in a certain part of the case to control the airflow specifically to an area. Also, it appears you had room for a larger fan? Maybe look into a 40mm server blower instead? They move WAY more air, allowing far slower (quieter) operation at lower speeds. Also, duct the heat upward for the exhaust, putting the vent holes on top, rather than the side, and you'll lose a couple more degrees easily. Intel RealSense cameras. Well, they're still rather expensive. You can buy a "replacement camera module" that has RealSense for some Dell laptops for about $12-15USD on AliExpress, and another $2 for a connector and sacrificial USB cable. I use several old laptop webcams as security cameras, and they're all just USB devices. Much easier to embed that way. Oh, and if you have a Kinect 2.0 from an Xbox One, you already have one. USB/power adapter will cost next to nothing. 5-10 on eBay last time I checked/bought one. Cheapest ways to get "Windows Hello" and similar security up and running. Man, I need to order one of those little touchpads... 😆 Thanks for another awesome video! My partner might not be as thrilled at all the new ideas and tips I get here, along with the "crazy projects", but I sure appreciate it myself! 😁 (Also thanks to the people in the comments who participate, as you guys have been a great help as well, often saving me time and failed ideas, since someone's already tried it and the group is solving the problem. Many minds!)

[@DIVERGEsound]

Thank you for simplifying this process!

[@kevinhiggins320]

Thanks @Skyentific :D

[@Skyentific]

Thank you, for your comment!

[@shengzhiwang2143]

Awesome video! I also want to build my own bipedal robot. I would like to use ODrive as motor driver as well. For the control board (or in facy way, the robot brain), I was wondering the difference between Jetson Nano VS NX Xavier? Why don't you choose NX Xavier? Thanks

[@VideoStefan17]

"do not hesitate to leave the comment" i did not!! ;) great work!

[@johnmarch5969]

Great setup!

[@andresgodinho]

The fan could be temperature controled... That would make it less noisy. As always great vídeo!

[@jonwatte4293]

The nano has a 5V PWM fan header and Noctua has 10mm and 20mm thick fans size 40mm that work with that. But then the power supply wouldn't get constant airflow.

[@andresgodinho]

@@jonwatte4293 constant air flow isn't as important as constant temperature (in my opinion) and then it would be super easy to implement a temp. sensor near the psu and get readings from there. This would prevent overheating while maintaining a fan speed ajusted for the condicions inside the box.

[@quinnfoster4671]

One time we ordered all of our parts for our robot for the season from vex robotics, they accidentally shipped us a Jetson and we had to figure out what it was and whether we had ordered it. We just ended up sending it back because we were using a raspberry pi and webcam for our vision tracking.

[@jjjmarianito]

I always see your videos, unfortunately i don't have a lot of money to support but when i can i will do, keep the good work.

[@Skyentific]

Thank you! Likes and comments are also great way to support!

[@billfield8300]

very well explained. Great Vid. Thanks.

Do you have recent plans to build a quadruped legged robot or maybe just one leg ? and what about my suggestion about uploading speeded videos of your part's software design and assembly :)

[@evilunicorn9205]

Great channel, thanks for the effort.

[@bence4642]

Very cool. I really like the 3D printed box. Looks very clean with it. By the way, is it a good idea to put a jetson nano onto a drone?

[@jonwatte4293]

The nano is not very heavy, so if you can generate stable 5V/3A for it, the Baboo should work on a medium or large drone. Also, probably doesn't need additional fan if it's on a drone!

[@bence4642]

@@jonwatte4293 Thanks for the answer! I was thinking about using it for computer vision and some other AI stuff.

[@raguaviva]

nice setup

[@EricRohlfs]

Any issues with heat in that case? My nano gets super hot when doing AI. Beefy case though, can drive a truck over it. After blowing up three other power supplies ... time I open the wallet and get an odrive. Setting up the Realsense was a pain for me too. I really wish Intel and Nvidia would work that out!

[@NielsNL68]

hi, where did you find that touchpad? and how is it performing?

[@neur303]

The way you secured the cables most likey nothing is going to ever happen, but the proximity of main line and low voltage lines make me a bit uneasy :) Isn't there a better way to keep those apart? :)

How many motors does it can control simultaneously?

[@gweliver]

How much for a printed case? I do not own a 3D printer yet

[@AdaptivePhenix]

More great stuff 👍👍 However, it's by no means the perfect robot brains. For that, you need to get away from the mainstream stuff and look at the Parallax P2....8 CPUs and "smart pins"... Does hard real-time and is child's play to program in several languages. Apart from the normal analog/digital functions, all of the smart pins can directly interface to quadrature encoders....absolutely no need for antiquated interrupt nonsense 😁😎

[@christophemalvasio5569]

@Skyentific why only one camera ? you need more for this robot to see and act in 3d

[@YOUnoobGER]

One depth camera can be enough.

[@christophemalvasio5569]

@@YOUnoobGER motorized maybe but not very efficient i think

[@Skyentific]

This is camera made specially for the 3D vision. It has three cameras: one standard, and two infrared. Like this it can make normal image and 3D depth image.

[@Skyentific]

Yes! I also think it should be enough.

[@Skyentific]

I also plan to motorised it in the future.

[@timhoksong5608]

Does your jetson nano have ROS installed?

No, it is not installed. But probably it is possible to install.
