Battery life #15

Closed sgcarrier closed 7 years ago

sgcarrier commented 7 years ago

Currently at the 75 to 80% mark, the battery dies. This usually manifest as a sudden jump in the read value of charge to an absurd number ( 65535 or something). Its -1, but since the expected value is unsigned it gives this maximal value of a 16-bit representation. Since we expect the robot to take into account his current charge in his learning, we should probably investigate this battery or find an alternative.

Perhaps a cleaning cycle could help the battery or maybe replacing the battery by another or by normal rechargeable alkaline battery is the only way to go.

There is a nice forum here about hacking the APS battery: http://www.robotreviews.com/chat/viewtopic.php?p=77882

New battery bought for the experiments. It should allow for longer lifetime.
