Realization and performance assessment of a force-sensing based smart floor panel for indoor localization applications

摘要: Abstract Accurate position detection of indoor objects is crucial for many intelligent life applications and can be realized by various approaches. In certain applications, performed using some forms touch-based floor sensing systems to avoid problems faced vision or inertial navigation The present study develops a panel test stage (1 × 1 m2) its associated localization schemes based on rigid body statics evaluating the feasibility positioning performance determining locations moving such as mobile robots. motion signals are detected four load cells located at corners used determine applied forces means statics. Essential tests examine system performance. Noticed that due existence boundary reaction moments, traditional predictions may not sufficient calibration procedure required. parallel, accommodating different possible scenarios, corresponding estimating force-applied readout history algorithms also proposed realized. results indicate accuracy approximately ± 1 cm over 1 m span after calibration. Although method essentially static, it still detect object provided frequency less than 2 Hz. Furthermore, demonstrations presented highlight other center gravity measurement fusion multiple in environment. Finally, an demonstration both wiimote IR LED this smart elucidate application work sensor control.
