hi Peter,

I would like to try it to recognize object (form and color) doing some tracking.

But in fact i can have a very efficient form analyser neuronal program much better that whet we can find in in shop.

So i want to give eye to the robot and then send the frame to the analyser.

Of course i will need a fast microprocesor to do this or send the frame to my computer witch will do the analizing work.

There is may be somme camera that may do the analizing frame work and send instruction to the javelin or something
connected to it.

As i do not know all the robotic module. If you could help me to choise or to give me some direction to look for, that would be nice.

Regard herve

Parallax sells a camera especially for the boebot.

Attached are some cmucam files I found on my pc.

Hi,

Does the CUMcam2 and 3 could work with the jevelin ?
even if i must buy another microcontroler to connect it to the javelin ?

Peter Verkaik

Probably, but you will need to develop new javelin classes for it.

Hi,

It is possible to know how to connect the Cmucam to the javelin.

1)
Do i need to connect the TTL serail Pin of the Camera Board to the IC2 pin of the javalin ?
· "Note that, it is necessary to remove the max232 chip to use this port"
Or do i nedd to use the Level Shifted Serial Port· to connect the Camera to the IC2 javelin pin ?

2)
Concerning curent consommation. The documentation said that the CMUcam consume about 200mA. Which is higher then the javelin stamp dome board. Do i need to connect the cammera to an external batery ?

3)
i read the documentation concerning Cmucam1,2,3 it llok like they shloud be working whit the javelin !

thanks

1) You need to connect the TTL serial pin to a javelin I/O pin (P0 to P15),
and then setup a Uart for that I/O pin.

2) 200mA should not be a problem for the javelin demoboard.
Just be sure to use Vdd (= +5V) from the right upper corner,
that is, if the camera requires a 5V power supply. Otherwise
use an external powersupply and connect javelin GND to this
external powersupply GND.

3) You need to write your own camera classes.
