Networking question

Dgswaner

to be short I'm having RF Issues on my web controlled bot. I'm really liking what I see with roborelm and so I decided to put a PC onbaord for the vision control software. it will have a wireless connection to the internet.

My question: If I put the PINK onboard add a second NIC to the computer and bridge the to network cards that will give the PINK internet access right?

is their any performance loss with this method?

I may be misnderstanding your needs or configuration, but I think life would be easier if you added a hub or switch to the single NIC and connected the Pink and wireless modem to that. With a second NIC, your PC would have to be running some sort of router software to make the two nets talk to each other.

this is for a mobile robot, and I didn't want to add any more hardware then necessary. because of space and battery life. I've never used a network bridge before but I thought it's intended us was what I'm wanting. I guess I'll just try it and find out what happens.... I'd rather add a switch then a software router, it's not the fastens computer and it will already be streaming video and running roborelm.

thanks

If you now have a computer already on the robot, do you really need to keep the Pink on the robot?

If the answer is yes (as might be the case to support some pre-existing configuration) and the computer is running Windows XP, I may be able help in configuring the computer to share its wireless connection through its hardwired network connection.

Let me know if this is the case.

The PINK is to store sensor data and take commands via the web. I think it needs to be on board, or RF link. which I'm not able to get working. so I'm hoping I can get it to work. from what I've read about bridging, this is exactly what it's for. but that's PC to PC. I'm thinking pink connected to the PC via crossover cable, bridge that connection to the wireless connection. in theory I think it will work. I'm working on getting the PC to boot from a USB drive then I'll work on the networking. thanks for the offer I'll let you know how it goes.

if the computer is sending serial information to the robot it might simply be more feasible to ditch the PINK(no offense to Parallax but PC>Pink [noparse]:)[/noparse]) and just install a simple web server w/ PHP(it's actually quite easy, I set one up when I was in the 9th grade). Some quick and simple PHP + a second COM port(or maybe the first can be bridged, idk) + Some Router Management(to forward the appropriate ports) = Full featured web controlled robot

well I just read that booting Windows on USB 1.0 drives can take up to 5 minutes to boot so I'm scratching that idea.

Diablo, where were you 18 months ago, i looked and look for info or people to help me do just that, then the pink came out and so i picked up one to solve the problem. could you tell me a little more about what is involved? can I set up a series of server variables? I don't know which way would be best. I already have the web interface working with the pink, but I do have space limitations with the pink.

thanks for the input

Dgswaner,
I use a desktop but you are right about bridging.
My desktop has a wifi connection with a router. My pink is connected to a wired lan card
in my desktop, using the (red) crossover cable supplied with the pink.
I assigned my pink a static address 192.168.2.70 (I used 70 because the pink is a SB70 print
which makes it easy to remember).
All you need to do is open network connections, select the two networks that you like to bridge,
(hold down CTRL and click on both networks), then rightclick and select bridging.
(This is on a XP SP2 machine). After that I could sent emails, and send/receive udp messages
from the desktop·and I didn't even had to adjust firewall settings.

Edit: an option for a fast bootable mobile solution would be an eee pc from asus.

regards peter

Dgswaner -

Here are some of my ideas/suggestions:

As far as boot times and such I have two suggestions: One I'm fairly sure isn't legal and the other cost money :P

*NOTE: I do NOT condone piracy in any form, This information is ment to be educational

• Method 1: TinyXP

  [noparse][[/noparse]DiablodeMorte] - Ok, sorry, Note to readers: TinyXP is the non-legal solution
  
• Method 2: Stripping down an existing version of Windows.
  As to my knowledge, this method is legal. In this method, a piece of software is actually bought that then uses a legal version of windows and strips out all the unneeded things. About 30 seconds of google search discovered this peice of software: http://www.litepc.com/xplite.html. I've never used this software but it seems to be for more "advanced" users.

As for more information on by post suggesting the use of a webserver on the PC. It might be more beneficial if we talked over IM. If you could just send me a Private Message I'm sure we could work it out.
