I'm trying to test out the follower example on my turtlebot. Everything seems to work fine, I start the follower app, the kinect comes on, then as soon as the motors move the kinect shuts off. Sometimes the robot will move a little bit before it shuts off. Other times it seems like the kinect is still running (red IR light is on) but the robot doesn't respond at all.

Here's what I get out of the follower app.

Looks like it's a hardware issue.

I brought the kinect up. Then drove the robot around using the joystick teleop. When it's moving very slow, the kinect stayed on. But if it went faster the kinect died. I verified that the voltage to the kinect is fine so it must be a current issue. I would think that the battery pack could source plenty of current unless my batteries are going bad?
