[Ros-kinect] Powering the Kinect from an Erratic robot.

Gonçalo Cabrita
Hi everyone!

I just got my Kinect (yay last guy in the community to get a kinect :P)!!!

So I'm about to cut the power cord and I want to install my Kinect on an Erratic robot.

The Erratic has a 12V line, however when charging this line can go to as high as 14V.

Does anyone have any idea if the Kinect can take the 14V input voltage? Any idea on what voltage regulator it might have inside?

Thanks in advance,

I did not dare to experiment with the input voltage for the Kinect sensor. A friend pointed me to the SKE15A-12 DC-DC converter (http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_155708_-1). Unfortunately it is quite expensive but it works well and is a safe choice for the Kinect sensor. I am using it on my robot which is powered by a 12V lead acid battery.

I used that exact same adapter in my robot Maxwell. Works quite well on a 12V SLA.

Hi Gonçalo,

For a relatively inexpensive 12V regulator circuit, you might look at the following tutorial:

http://www.ros.org/wiki/kinect/Tutorials/Adding%20a%20Kinect%20to%20an%20iRobot%20Create

The question for me regardless of the regulator used is: do you want the regulator + Kinect hooked up at all during recharging?  By that I mean, will the regulator handle the higher charging voltages without overheating?  14V does not seem too bad, but on the iRobot Create, I have measured as high as 17V on one of the 12V pins during recharging.

Thanks for your replies guys!

I guess I'll chose the safe way and make a simple board to power the Kinect, the Erratic has got a 19V line I can use. I'll use a cheaper DC DC converter from Traco though :P
Not a good idea to blow the Kinect up on the first week!

I've used the circuit linked to above, with no trouble at all (on a Create). The Create's unregulated-battery-voltage pin can be as high as 18V during charging, and this poses no difficulties (other than heat dissipation) for that circuit. When the Create isn't plugged in, it provides more like 17V, which doesn't even have heat problems.

If the Erratic provides 14V (and enough amperage), you should be fine.
