Subject: [DPRG] warped battery box failure

Hello, today at the monthly meeting, my robot had a no power problem. It 
was dead. I found the failure and thought it amusing. It was the last 
thing I would have thought of.

The plastic battery box has warped enough that there is no longer contact 
between one of the metal plates and the anode of one AA cell.

This battery box will be replaced with some aluminum battery holders.

Anyway, this is reminiscent of the usual wisdom that connectors are common 
points of failure. But usually we think of I/O instead of power contacts.
