Hi i'm making a robot that has 2 cameras on it and now i'm stuck on how to get image from the cameras to my pc what is max 100meters(9140? yards) away from that robot. the cameras i try to use are usb webcams (the cheapest i could find). I thought using WiFi cause i have one for my laptop but some of the guys sed, i could'nt use them cause they cant send USB data... I dont have no PC's on that robot and ar not planing them either. only some pic's to control my robot.
I would like to send image from my robot to läptop and some data from my laptop to the robot aswell(commands to the pic) so it has to be a tranciever styled thingy...
as i can see it also has integer WiFi but on what distance can it communicate with my laptop.
and it has only 1 usb port. i have to use a divider to get two? and how to i get the image from thad ppc to my laptop? and can i hook up my pic to it also?
Ok well... let's lose the camera.
leaving only RF communication with robot and my laptop. are there any cheap wayss to do that? 1 channel needed only. to send data from my pic to laptop (sensor values) and some commands from laptop to my pic. range is 100-30m
I would suggest you look at instead, this one includes the required encoding/decoding so you can send standard serial data. Otherwise you will have to write your own routines.
You can't send standard serial data over an RF link, basically because it's AC coupled - usually manchester coding is used, but you are quite free to invent your own :lol:
They will transmit variable width pulses, again though, within the constraints of their AC coupling - you would need to experiment. The more expensive ones come 'ready to use', with a pre-programmed PIC doing all the work for you.
ok well i chose SC-P tranciever module from linxtechnologies.com
is it any good? is it "smart" (inside coding) what and when do i send to it? can i communicate wit it via i2c? or serout?
