Gehintention detecting device and system and method thereof

A Gehintention detecting device and a system and a method thereof are provided. The Gehintention detecting apparatus includes a lower support portion into which a foot of a pedestrian is introduced, and an upper support member mounted to the lower support member to cover an upper surface of a foot and a heel of a pedestrian. A tension sensor is disposed between the lower support member and the upper support member and configured to measure a power supplied to the lower support member and upper support member in response to a walking motion. In addition, a Gehintention is detected when the portable robot is used to provide the stability of the Gehoperation, thus the marketability and comfort is improved, and the Gehleistungsfahigkeit of the portable robot is determined by the simplified mechanism, whereby higher operability is created at a low cost ,
