Abstract
An intelligent door lock system has 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 the lock device. The lock has an off center drive mechanism relative to an outer periphery that allows up to R displacements from a center of rotation of the lock, where R is a radius of the lock. An engine is provided with a memory. The engine is coupled to the positioning sensing device. 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.
