When someone else puts the robot to bed
Put to bed by someone else, the robot kept tracking my face and making noises. It now understands it has been put to bed, and a startle no longer makes it lose my face.
Energy and sleep
The battery, and going to bed properly. 5 of 5 skills learned.
How long it lasts: four discharges and a gauge
About three hours asleep, between 1 h 35 and 2 h 23 awake. A gauge right within a few minutes, a green LED that lies, and an empty battery that makes it reboot in a loop.
A real night
Sleep mode now really puts the robot to bed: head tucked in, motors off, woken by a push on an antenna. And why it does not restart on its own after a power cut.
Reading the battery from the motors
The robot does not show its battery level. Its nine motors, though, know the voltage that feeds them. One reading, an energy tile, and a trap while charging.
Twenty hours standing: when an error does not put the robot to bed
A rare timing error, a program that only knew how to catch network errors, and a robot left with its motors powered for about twenty hours. Two rules since.
