Abstract: Aiming at the problem of the boundary recognition for mowing robot moving in a fixed workspace, the method of the boundary recognition based on the electromagnetic induction was investigated. The hardware structure of mowing robot and the principle of eddy current were introduced. Then recognition method was analyzed by the principle of eddy current and the eddy current testing technique based on the electromagnetic induction was applied to boundary recognition. The feasibility of the proposed method was verified according to the distribution characteristics of the datum from the experimental results under the mowing robot platform. A recognition algorithm using electromagnetic induction boundary was presented and verified. The experimental results indicate that the proposed recognition method of boundary based on the electromagnetic induction is valid for mowing robot application. In addition, the proposed method has good adaptability, low cost, easy maintenance, etc.
