Let's Make Robots!

Video transmission

Hi everyone,

I'm quite new in all of this, but i want to build a robot able to transmit video, and possibly sound. I've got a common webcam and I want to make it wire less, but I don't know how to do it.

I would apreciate any help from you lot.

Hi cpu_manu,

I have 2 common usb webcams, and I wanted the same thing. I wanted it to produce a wireless video feed and I'm working on ranging with stereopsis. What worked for me was to use a regular computer for my robot. The computer has a standard wireless network card. Here are some pictures:

This looks very cool and interesting, GroG!! :)

Hi Frits,
thanks ..  just starting to get results - it has taken a lot of work.  I'll have a walkthrough relatively soon..  too slow & not good enough matching yet - there is an amazing amount of good firmware & software people use in their heads without even thinking about it ... dang machines are stupid, and i'm not the best machine instructor :D

At times like these it really iritates me that we are just a web community, it would be so cool to pop over for a beer and some chat on stereo :) I am sure it would be more productive..!


Well, your formally invited to my house for beers and "shootin the shit" <-(translates to "western talk") - heck .. everyone’s invited ( except that damn asusmps5, asusmps6 and other spammers ) ....

Yeah .... I know what you mean ... my neighbors are great, but their eyes slightly glaze over when i start spouting off about, "Your visual cortex has a phenomenal ability to range distances with passive radiation - you would be seeing double all the time if it wasn't working, you know when you get hit in the head? In fact I think infants see with "double" vision .. so this ranging ability is probably more software than hardware...blah .. blah ... blah" 

 Seriously, if your ever in my part of the world ... look me up ...  my work is of far superior quality when beer is involved !



Thanks, and same over.

Regarding the spammers; I'd actually love to see the fukkas in my shed. Serious talking down, followed by some ass kicking & I know where you live - kinda stuff would happen!

...that's all I'm sayin'.

Thanks for the info. Anyway, I was thinking in a much smaller robot, I've thought about using a similar system to the one audio and video transmiters for home use.

If anyone knows how to "reproduce" this, please tell us and give instructions for the construction.

Thanks all.

Well, to tell the truth, composite video cameras are the same price as webcams. Sure you need to buy a transmitter, but you can buy a transmitter receiver pair for less than $40.

I use a disassembled 2.4GHz video sender unit. It's great because the transmitter is also an IR receiver and the receiver is an IR transmitter, so I could send IR to the bot and receive video back.

If your issue is only size, not price. Maybe you could try hooking up your cam to a palmtop computer. Many of these have wifi and bluetooth..
