Abstract
An obstacle detection system includes a first component and a second component. The motor is configured to move the second component toward the first component. Radio frequency identification tags (RFIDs) are connected to one of the first component and the second component. A controller is operatively connected to the motor and has a transmitter operatively connected to the other of the first component and the second component. The transmitter is operable to create a magnetic field between the first component and the second component. Each of the RFIDs is operable to provide a respective signal in response to the field. The controller is configured to modify power delivery from a power source to the motor when the respective signals received by a receiver change due to at least a portion of the magnetic field being at least partially blocked or attenuated. A method of detecting an obstacle is also provided.
