Laptops: Will You Guys Use Them On The Robot?
 

Now that the rules allow for laptops to be utilized as an on-board system on the robot, will any of you utilize it? Well I know I will. Computer Imaging is going to eat up a lot of computation power. I am gonna look into CUDA and see if that will help with the image processing. :mad: Now that it is the build season no time to slack off:p I hope parallel processing is the answer to autonomous robots.

Possible Uses For A Laptop:
1.)Signaling system:
The screen can display the color of the tube that the robot needs.
2.)Computer Vision:
The laptop can bring in images captured from web cams and process the various objects on screen. To make things even easier, OpenCV can be used. Honestly, I do not have the guts to write the whole thing.
3.)Artificial Intelligence:
The laptop can crunch numbers and data to generate the best route to take to score or pick up an object. That can be either transmitted to the driver or the robot can carry out the assignment itself.
4.)Decoration:
You can just stick the laptop on the robot and have a screen saver of your team logo or some shout outs or something like that. I wouldn't be surprised if some team did that.


Anything else to add?

Well, after floating around ideas with a mentor from MaxBotix (They're not even five miles from our school, and yet we've never heard of them or contacted them for the past three years), I'd have to say no to this one. A mix of cheaper sensors, mainly the line following devices and ultrasonics, can do a far better job at mapping the whole field, and far quicker, than any camera system for a field of this size. As for artificial intelligence, the Crio is still capable of plotting routes, the best routes, mind you, on the field hundreds of times faster than necessary with the right code.

Where are you reading this?!?!

This form has some discussion of weather or not it is even legal to put a laptop on your robot.

For me as per R19 "No individual item shall have a value of over $400.00. The total cost of COMPONENTS purchased in bulk may exceed $400.00 USD as long as the cost of an individual COMPONENT does not exceed $400.00."

It says VALUE not cost. If you jack this $200 dollar laptop with $1000 of software in my eyes this would put the value of the laptop at $1200 and would be over the limit as per R19.

Now do you think we would have to resort to using those "rugged" computers or would the regular consumer laptop be durable enough?

Mr. Drake: Rules R34, R45, R50 allow laptops. Last year there were no rules like that.

Re: Laptops: Will You Guys Use Them On The Robot?
 

It depends, really, on where you place it. Undoubtedly, hard drives will be a no-no. I think it's quite possible with a bit of shock absorption on the laptops body that a regular laptop with a solid state drive would work.

you could just drop the hdd. Boot linux from a flash drive or sd card ...

<R45f> specifically allows drive motors in COTS computing devices, and fan motors in COTS computing devices and speed controllers

I believe the post was referencing the likelihood of hard drive failure in an FRC environment, not the legality of a hard drive itself.

Re: Laptops: Will You Guys Use Them On The Robot?
 

Really the only advantage to an onboard laptop would be image processing. I'm still not convinced that we're going to have to do so much image processing in order to be competitive in auton, so it seems like putting a laptop on your robot is a big risk for little pay off.

If you're thinking of a notification system for the feeder, I doubt a laptop screen is going to be bright enough to be seen across the field (especially when compared to an LED array).

Wouldn't you be stuck with the $400 price limit from <R19>? With that type of a budget... you'll still be stuck with a little Atom powered netbook (and probably not with a SSD). I don't think it will give you much of an advantage. I tried video processing on a little dual core HP Atom powered netbook, and it struggled to keep up with everything else. We have a really powerful cRio that is designed to do so much more than we're throwing at it right now. With the correct tuning, we can almost do anything with it.

In response to:
"Technically one can buy a very low end, but upgradeable laptop priced just below $400 and buy the upgrades necessary to make it more like a $600 laptop. There were no rules about that. Just buy them in separate orders."

Section 4.3.5 of 2011 Rulebook
"G. If the item is part of a modular system that can be assembled in several possible configurations or applications, then each individual module must fit within the price constraints defined in Rule <R19>. If the modules are designed to assemble into a single configuration, and the assembly is functional in only that configuration, then the total cost of the complete assembly including all modules must fit within the price constraints defined in Rule <R19>. "

Well... as I think about it... the laptop is modular. You can separate the RAM, battery, and SSD. Still... you're going to be stuck with a fairly low end laptop. If I were to even consider this, I would attempt to make a PC from scratch with a mini-ITX board or something. Still, I don't see the big advantage.

Re: Laptops: Will You Guys Use Them On The Robot?
 

Exactly my thought sir, but desktop computers run off of AC power. Is the robot able to produce 110v AC? If it is, I am dropping the computer Idea and going straight into PS3(s). They are cheap, $250 for the refurbished ones. 6 SPUs available to the developer and homebrew broke into the scene. If the budget allows, we can use 2 or more as a distributed memory system. But that would take lots of weight to do. I am dreaming big here.:rolleyes: :D

Folks - Don't forget to take 15 minutes to look into using a Gumstix computer if your goal is more number-crunching.
