Pioneer Gripper
Next, does the ARIA
demo
program display apparently valid Gripper sensor readings? For
example, do the paddle switches indicate closed when they are closed, and open
when they are open? And do the breakbeam IRs work? If so, it is likely that the Gripper
power cable has become disconnected either from the Gripper control board or from
the battery board connection.
Loosen the Gripper from the robot’s nose first and check
the latch-locked connection. You might even test it with a voltmeter: the yellow wire is
the positive terminal and should read battery-level (around 12VDC) voltage. Easily
access the battery board through the rear plate of the top deck, as needed; you need
not remove the entire deck plate as you might have when originally installing the
Gripper.
The only other possible cause is the control cable. Make sure it’s connected to both the
Gripper control board and to the User I/O-Gripper connector on the controller.
If all else fails, contact
Activ
Media support for more assistance.

The Gripper power cable supplies its motors; the Gripper signal cable provides power to the Gripper’s sensors.
