How do you exactly connect the camera to the board, there must be some type of input you need to hook it up to. And then how do you connect it to the Computer with and without the controller board. We have the servos and stuff already mounted.
My team and I find the instructions in other places confusing and I dont want to plug in the power through the wrong place -_-
How do I hook up the camera exactly ? Do I connect it directly to the servos or should I connect the servos to the RC ? should I allow the camera to be move by a servo left and right or should I try to mount it without a servo and let the robot motors control it’s left-right movement? what is the best way to do this?
Does it make sense to connect the servos header from the CMUCam into the RC analog inputs and send the signal to the servos using the PWM outputs on the RC so i control and monitor the camera’s movement?
Here are a couple of other photos to help. The servos are driven by the camera by those wires at the top. We had to reverse how the camera drove the servos, but you cannot quite see the jumper used in the photo.
There are two different ways we hookup the CMU camera:
to a PC to run the CMU GUI to get the calibration numbers and to test the camera. At the regional events the FIRST staff will give you the calibration numbers. These numbers have to be typed into the CMU camera code (v2.4). The GUI is in the IFI Robotics download http://www.ifirobotics.com/docs/cmucam2-documents-and-software1.zip
You’ll find the GUI under the folders Software\CMUcam2GUI_fe\stand_alone and is called CMUcam2GUI_fe.jar
to the RC to drive the robot.
You cannot have the camera hooked up to both the PC and the RC at the same time or it just won’t work.
The camera draws power through the cable connected to the RC pwm output.
The PWM output power is only supplied by the small backup battery attached to the RC.
Only the center red wire of the PWM cable is actually used. The camera doesn’t care what the PWM is set to in the code.
Yea i noticed that too, the cam wouldnt work without the battery, i read over the manual again to see if it provided that we needed anything else, and there it was… you need the back up. Hooked it up and the lights went on I was happy .
