4.2 RFID Detector, Identiﬁer and Co-ordinator

The existing detection technique does not produce reliable data due to the

double-trigger eﬀect outlined in Section 2.1. The proposed solution is to

replace the two optical sensors with two independent RFID readers. These

readers are placed along the same penguin path, separated by a few metres as

shown in Figure

4.1. Both readers will continuously look for RFID transponders.
