2 CMU Cameras... AT ONCE!

[Mike Starke]

Nice work guys!
I like!


It'd be sweet to get both cameras, one to track one target, and the other to track another, and place a tube in one of the rows where the light box isn't. Can't wait to see it in action!

While the dual cameras are sweet and everything, I can't help but wonder what the music playing in the back of the video is...

Any Ideas ?

How difficult would you say it was to write code that used two cameras at once?

I'm currently trying to get the RC to talk to a single camera via the program port using Kevin's serial_ports code... no luck so far.

The port is specified as the first option in camera.h. Other than building a suitable cable, that's all you have to do.

Did you define the correct serial port in camera.h? And comment out the other one?

And a very important question: Are you using a null-modem cable?

I am using a male to male DB9 cable... I'm fairly certain it's straight-through, is there a special pinout neccesary?

[DanDon]

You can find the pinout for a null modem cable here. Basically, all the pins dealing with transmitting on one side are the pins dealing with receiving on the other side (i.e. The Tx and Rx pins are crossed), allowing the ports to talk to each other.

Thanks for the tip... works much better now. That was the easy part, now to modify the code to track on two cameras.

How quickly does that wear out your backup battery?

I want the charger from the main battery for one camera, I can't even imagine the worry about battery power with two...

Congrats cant wait to see it

1392's battery inst that bad, i can the camera for 2-3 days for only a couple of hours each day until battery is gone...

Happy to report that I have two cameras tracking independently as of about 5pm this evening :-)

[Sean Marks]

Nice Job. Fun to watch. hope it helps somehow.

now is this legal?.... if so do they (cameras) have to be the new 2007 models?

[Michael Corsetto]

Correct me if I'm wrong, but I believe the only part of the camera that can't be used from the 2006 KOP is the "motherboard", the thing the the CMU camera plugs into on the module (forgive me for not using correct terms, i am a lowly mechanical team member ) We ordered an entire second camera, with another mount, just to have a spare lying around incase things go wrong.
