The Ping Radar and object detector are on our BOB Robot and it starts working Fine with my Digital Ports - Then the Ping just drops out. The Object dedector sticks at the max distance and there are no red blips coming up on the Radar. I'm also running a servo for the head rotation tied in with the ping. Could this be due to low voltage to the EZ-B board ?
I checked tha battery pack and I'm getting 6.4 volts.

Where do I go from here as I'm not big on code and thus relying on the ARC gui for controlling the robot ?
Cheers

Anyway, thanks for your help guys - all appears back to normal

The ping is a bit strange when low voltage occures. It's less about the voltage (specifically) and more about the required current (watts). The servos/motors and other peripherals require current. The stopping and starting of motors/servos draws more current than when it is steady ON. So the PING sensor and the Servo/Motor may be on/off within the same time and low battery supply current will cause the PING to perform bad.
9 volts with 6 AA is okay for "some" configurations based on physical load of the servos. But don't expect the batteries to last very long. You may need to get into higher amperage batteries for your project if there are many peripherals
