Kinect power problem while connecting to the irobot create base?
I am having problem while connecting the kinect power using DB25 connector of Irobot create base. The connector circuit is designed by clearpath robotics to provide 12V DC power to kinect by taking power from pin 10 and 14 of DB25 connector of irobot create base.
I read to a tutorial by Prof. Jason O'Kane he says that :
For the Kinect sensor to operate correctly, it must draw power from the Create’s battery. (The 5V available from the USB connection to the netbook is not sufficient; the Kinect needs at least 8V. Note that seeing blinking lights in the Kinect is, in my experience, not enough to know for sure that the Kinect is receiving the power it needs.)
Your Turtlebot has a cable connecting the Kinect to the Create for this purpose, but by default that power supply is disabled. To enable it .........
**rosrun create_node kinect_breaker_enabler.py**
this command working well as I am getting power at pin 10-11-12 of DB25 but not getting power out of circuit board designed by Clear Path robotics. Actually this circuit board came with a turtlebot (with irobot create base)and I am using it with another independent I robot create base to connect the kinect but it is not working.
I tried this circuit back to the turtlebot with which it came and its working fine. Now my question is why it is not working with the other Irobot create base? Is there some hardware level coding for pairing of devices?

What is the output when you run 'rosrun create_node kinect_breaker_enabler.py'. Do you have a multimeter you can use to measure the voltage output on the kinect power connector?

Yeah, I got to check that and found that Irobot create base working fine and giving 14V on pin 10-11-12 with respect to GND at pin 10.
so its problem of the DB25 circuit board which I am willing to change now.

What is the output of
rosrun create_node kinect_breaker_enabler.py?Asked by ahendrix on 2013-07-31 16:03:17 UTC
14V on pin 10-11-12 with respect to GND at pin 10 of the DB25 connector of Irobot create base.

What is the console output of
rosrun create_node kinect_breaker_enabler.py?Is there any voltage on DB25 pin 19 (Digital output 0, which enables the 12V regulator)?
Is there any voltage on the connector (NOT the DB25) that goes to the kinect?

This problem is now got modified to a new form ... I am modifying the question with a more detail at the end of the question ......... Please read it and reply.

Dear Ahendrix ....... could you get the modified form of question ? please reply

You still haven't provided the console output from running
rosrun create_node kinect_breaker_enabler.pyor indicated if there's any voltage on pin 19 of the DB25 connector.Asked by ahendrix on 2013-08-05 07:24:40 UTC
I need to check Pin 19 as per ROS tutorial I just checked pin 10-11-12 w.r.t. GND at 14. 'rosrun create_node kinect_breaker_enabler.py' gives no graphical or text output on Terminal window.
