NVIDIA Jetson TX1

[dusty_nv]

Hello FIRST teams from NVIDIA Jetson team! Happy kickoff day to everyone!

https://a70ad2d16996820e6285-3c315462976343d903d5b3a03b69072d.ssl.cf2.rackcdn.c om/ed527c352ccdd344d0a48c7f6c5620a6

We're truly excited to be involved in FIRST season 2016. Here's our FIRST landing page: http://developer.nvidia.com/FIRST

If you are interested in using Jetson TX1 (https://developer.nvidia.com/embedded/buy/jetson-tx1-devkit) for your robot, we are offering all teams a $299 discount for Jetson TX1. You can obtain your discount code through here: http://www.nvidia.com/object/edu-discount.html The discount codes are send out every Mon/Wed/Fri.

Also, Jetson TK1 (https://developer.nvidia.com/embedded/buy/jetson-tk1-devkit) is included in the Kit of Parts. You can obtain with FIRST credits.

NVIDIA's Jetson platform includes powerful software libraries like GPU-accelerated OpenCV, VisionWorks, and cuDNN/Caffe for deep learning. Leverage them to unleash the 1TFLOP+ of compute capability offered by JTX1 module and power your robot with smarter brains and advanced onboard autonomy.

We'll keep an eye here on ChiefDelphi to help out anyone with assistance, but also feel free to post board-specific tech support questions on NVIDIA's Developer Forums (https://devtalk.nvidia.com/default/board/139/jetson-embedded-systems/) to quickly tap into the knowledge base of the Jetson community.

Our pals over at Stereolabs (https://www.stereolabs.com/) are also offering a discount for FIRST teams on their ZED (https://www.stereolabs.com/zed/specs/) depth camera, which uses GPU acceleration and easily integrates with both Jetson TX1 and TK1. Read more about it here: http://www.chiefdelphi.com/forums/showthread.php?t=141011

Like yourselves, we're also robot builders and tinkerers over here at NVIDIA, and nothing gets us more fired up then helping others enable their work. Hope to meet each of you out on the circuit and good luck!

[marshall]

Thanks Dusty!!!! I know we're excited about the possibilities with the TX1!

[gabriel_zed]

Thanks Dustin for citing us! The Jetson TX1 is indeed the perfect companion board for the ZED.

As you said, we'll offering during the competition a special price for FRC teams who want to use the ZED 3D camera for their robots. You can find more details here (https://www.stereolabs.com/blog/index.php/2016/01/12/zed-for-first-robotics-competition/) on our blog.

Also, we would like to thank Team 900 (Zebracorns) who integrated the ZED during offseason and published their code here (https://github.com/FRC900/2015VisionCode). http://www.chiefdelphi.com/forums/showthread.php?t=139410#postcount1506812
Great job guys!

During the competition, we’ll be here to help you, so feel free to contact our support team if you need anything. We wish you the best of luck for the upcoming Stronghold challenge!

Any ideas on feasibility of getting labview(vision module specifically) running on the tx1 or tk1?

We're looking at using a ZED(http://www.stereolabs.com) camera with either a tk1 or tx1 and am already familiar with labview vision so if possibly would want to explore that path.

Sadly the TX1 is not a supported LabVIEW platform. OpenCV works great though!

Does anyone know about getting these boards discounted internationally?

The website seems to only cater for US educational institutions.

Go to the Nvidia site and get in touch. They should be able to help you. I've seen some comments about international discounts on the Nvidia developer forums as well.

[dusty_nv]

The international academic discounts should be rolled out shortly, however for now we can help those FIRST teams directly. I send timytamy a PM.

[bhsrobotics1671]

I have submitted two requests for the TX1 both under my school district email and personal email and have not heard anything since last Sunday.

[dusty_nv]

Sorry for the delay, looking into the issue why these weren't already sent out. I e-mailed you the code from your entry.

ZED was brought up in one of our teams brainstorms. Unfortunately, at $449 it exceeds the $400 price maximum for an individual component.

The only stereo camera I've found under that is the $399 Leopard Imaging camera.

I am aware that LabView cannot be used to program the JTK1, but that alone does not mean it is entirely incompatible. What I/O does the JTK1 have that can be used for bi-directional communication with the RoboRIO?

Ethernet/TCP/IP/UDP/Etc...
Serial
I2C
SPI
Bit Banging
Smoke signals but letting the magic smoke out would be bad obviously...
Class 1 laser optic transceiver system: http://www.instructables.com/id/Laser-Transceiver/


Before you pick one... ask yourself what data you are sending and where, and why you are sending it. Some data that gets sent does not always need to get sent...

We used NetworkTables last year but we've found it to be slow for our purposes this year so we are investigating alternatives.

The data that needs to be sent:
1D array of
integer: target type (enumerated)
cluster: target location
X
Y
float numeric: distance to target

I'm thinking serial, and flattening all the data into a string, and then unflatten it on the RoboRIO.

Anyone using a ZED with a TX1? I have it working on a tk1 but still run into issues with image corruptions. I had to buy a mini pci-e USB module for the mouse and keyboard otherwise it was completely unusable with the zed going over a hub. So now only have the zed is on the usb 3 port but it still has sporadic image corruption. At least it's semi-usable now but still dog slow. The depth viewer only achieves around 5-8fps and some other examples not much better than that so if anyone has some data on the tx1 that would be awesome before we spend the money on something that may not be much, if any, better

[Greg McKaskle]

By the way, the LV network tables implementation allows you to control the update rate of the client/server, and it includes a flush call to force a send. Using the flush, and perhaps the rate, you should be able to get NT to have as little latency as a TCP implementation.

I'm not sure how much of this was incorporated into the v3 or network tables, but it was discussed.

Of course if the kids wanna write their own stuff, that is fine too.

With Jetson TX1 + ZED, I get 15 FPS out of the box (in HD mode) with the ZED SDK Depth Viewer tool. I often run it through a USB3 hub with the keyboard/mouse attached to that. Here's a link to ZED SDK for JTX1: https://www.stereolabs.com/download_327af3/ZED_SDK_Linux_JTX1_v0.9.2_alpha.run

Regarding your keyboard/mouse mini-PCIe USB setup, have you tried using the USB OTG port (normally used for flashing). With the converter you can plug USB2 peripheral(s) into it.

OK, yes we are interested, but maybe I'm missing something. If I am reading this correctly, we should be getting one in the KOP, or by PDV. I read this entire thread, looked on TIMS, but I'm not seeing how to acquire this amazing board. I see the discount of $299 for the Dev Kit. Is that what you are referring to?

What is the process to claim this beast?

I believe what they meant to say was that it was available in FIRST Choice. That's how we got ours.

Nope. They stated it the way that they meant. FIRST Choice is considered part of the KOP.

I was not aware that was an otg port, if it is I guess I could try that too.

the tk1 gets 5-7fps with the depth viewer on 720p so it sounds like the tx1 is ~3x faster with that type of load(assuming by hd you mean 720p rather than any of the higher resolutions). certainly an improvement but not as much as one would hope and the other question is if it's worth spending $300 for that...... corrupt frames are still an issue though so it may be worth the upgrade just to mitigate that issue...

It's slightly confusing, because there are actually two NVIDIA boards you can use as part of FIRST. There's the Jetson TK1 (quad-core ARM Cortex-A15 and 192 CUDA-enabled GPU cores, providing ~325 GFLOPS of compute), which was part of FIRST Choice (http://firstchoicebyandymark.com/fc16-127) again this year, but is now sold out in AndyMark - but if your team still wants to use Jetson TK1, you can order directly from here (https://store.nvidia.com/store?Action=DisplayPage&Env=BASE&Locale=en_US&SiteID=nvidia&id=QuickBuyCartPage). Since the list market price of Jetson TK1 is less than $400 (it's $192), it is permitted by the rules to be purchased outside of Kit of Parts and to be used on FRC robots.

On the other hand, if you want to use the latest-and-greatest Jetson TX1 (quad-core 64-bit ARM Cortex-A57 and 256 CUDA cores, providing ~1024 GFLOPS of compute), this board is available to FIRST through our academic discount here (http://www.nvidia.com/object/edu-discount.html). Fill out the form, including your info and FRC team number, and in a few days you will receive the discount code via email. Then enter this promo code when ordering (https://store.nvidia.com/store?Action=DisplayPage&Env=BASE&Locale=en_US&SiteID=nvidia&id=QuickBuyCartPage). With the discounted price of TX1 also under $400 (it's $299), it is also permitted by FRC rules to be included on your robots.

Please don't hesitate to get in touch if you have questions or concerns!

Thanks -
Dusty

The team at Stereolabs has been working with our optimization guru's over here at NVIDIA, so there's a chance that the performance gains could continue to improve throughout the season. If the speed/throughput of the stereo disparity calculations is your primary concern, there are a couple approaches you could take to mitigate - Stereolab's disparity depth field is high-quality - you could try using stereo block matching from VisionWorks or OpenCV which may be acceptable to your application. If you want to offload the formulation of the stereo depth field, there are also various structured light and time-of-flight sensors available which provide the depth field straight away, leaving more headroom for exploitation on the host.

How does one deliver 19V power to a TX1?

Edit: Better question: how low can the voltage go and still run the TX1 development kit?

We have the same question. The box shows it's rated for 5.5-19.6v. We were having some issues running it on 12v last night. Just curious to see if other teams have found another solution already?

It will run off of 12v. It will run down as low as ~6V without causing serious performance issues.

We have yet to solve the issues with the TX1 and how sensitive it is to voltage fluctuations. The board will power down at the slightest breeze of a voltage drop from our experiments... we're actively investigating workarounds.

Yeah, seems to be the issues we are having. In your testing does the TK1 work fine with no issues?

We have used these to boost our battery supply voltage for voltage sensitive electronics. http://www.amazon.com/DROK-Automatic-Converter-Regulator-Adjustable/dp/B00JKG57T4/ref=sr_1_7?ie=UTF8&qid=1455916779&sr=8-7&keywords=buck+boost

I'm assuming there are no rules preventing the use of this on the bot for competition that you are aware of?

[lucas.alvarez96]

Has anyone made or has a CAD of a case for the TX1? We're going to use the board on our bot and decided that the necessary protection is a must.

We have it still mounted to the black board it comes mounted to, then we mounted that with brackets that are riveted onto that board with a piece of lexan guarding it. I'll see if I can get a picture later, but for us we did nothing special.

After 3 hours struggling with the massive STP file of the TX1 board supplied with NVIDIA and a laggy computer, I was starting to get something decent for 3D printing. Seeing this post and link has probably been the most bittersweet sensation during the season. Oh well. :confused:

No but really, thanks Marshall!

Would there be any negative effects if we mount the board upside down? I want to avoid having the hole for the fan exposed to the world (AKA metal shavings from last minute repairs on the robot)

[Nemo]

We ended up buying a 12V to 19V converter:
http://www.amazon.com/gp/product/B00M3SR51Y?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s01
(http://www.amazon.com/gp/product/B00M3SR51Y?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s01)

I haven't dug into the rules closely enough to find anything that rules those out, but I suppose I'll do that while I'm studying up for robot inspecting.

We might end up using our mentor's TK1 instead. It's smaller, lighter, runs on 12V, and it talks to the cameras we bought unlike the TX1.

[marshall]

Have any teams had success with getting the TX1 powered via the robot?

I'm working on a write-up that describes what we have done and I can tell you it's not as simple (https://devtalk.nvidia.com/default/topic/916141/jetson-tx1/couple-questions-about-power/) as a 12v to 19v converter...

Is the TX1 significantly better for simple OpenCV hardware acceleration than a TK1? I am looking at how to get vision done for our team, and don't want to spend the extra money if we don't have to. Our original plan was to use a raspberry pi, but the processing power seemed to just be too low.

We tried similar without any luck... The TX1 really wants a constant voltage.

We were able to get some help from Nvidia and the following modifications to the the TX1 actually seem to work nicely:

We now have the makings of a TX1 on our robot with something special in store for keeping it powered that I'm sure is going to draw some looks from inspectors. More details to come after our upcoming event.

Yeah, this board is not for you. The TK1 is definitely better in terms of CPU/GPU power than the Pi but honestly, stick with the Pi and the basic examples until you get them working then move on from there.

Which change did you do? Disable the circuit or change the capacitors?

I think we are just going to stick with the tk1 this year.

We changed the capacitors.

[RyanShoff]

Using a supercapacitor would be in a grey area of R31 and R32 in my book. It's probably not a "battery". But it might be a "source of electrical energy". You wouldn't have a COTS exemption.

EDIT: If you are using the supercapacitor linked in the Nvidia thread, I can't believe any inspector would let that pass.

Shockingly (Get it? Pun intended) it cleared inspection by multiple inspectors. I'm not sure what the "COTS exemption" is but the circuit works and is very safe. It is held securely inside of a larger protective case and I don't personally think it poses anymore of a hazard than someone strapping a lithium-ion battery inside of a laptop, phone, or tablet onto their robot.

More details and specifics about the circuit to come. We just got done with our event. It was a blast and we had a crazy amount of fun.

[bhsrobotics1671]

We used the device linked and passed inspection with no issues and had 4 inspectors in our pit at one point (a whole other story). We had no issues with power on the board this weekend with the exception of our heat sink coming loose which prevented the board from powering on.

Overall it performed well, we just have some PID bugs to tune on the robot side of things.

Wow... I'm impressed. We've had nothing but issues with everything we've tried, except the capacitor.

[granjef3]

I got the TX1 board running off of a second VRM using option #1 from this post on the nvidia forums. (https://devtalk.nvidia.com/default/topic/916141/jetson-tx1/couple-questions-about-power/post/4824595/#4824595) They warn about the hard shutdown being possibly an issue, but the board seems to be powering on fine for now.

Haven't tried connecting to it yet after a few startup/shutdown cycles or driving around, as we ran out of time in the lab.

Marshall, did you try Option #1 before moving to Option #2 for changing the capacitor values? We didn't have any capacitors on hand that were the right value, let alone size. Also, could you provide more info on the supercap you guys are using?
