Abstract
An intelligent door lock system includes a position sensing device configured to be coupled to a drive shaft of a lock device. The position sensing device senses position of the drive shaft to assist in locking and unlocking a lock of a lock device. An engine with a memory is coupled to the positioning sensing device. The engine in operation processes information regarding an amount of friction experienced by a door or lock device when being opened and/or closed. A circuit is coupled to the engine and an energy source. A device converts energy into mechanical energy is coupled to the circuit, positioning sensing device and the drive shaft. The device that converts energy is coupled to the energy source to receive energy from the energy source.
