Erob movement trajectory algorithm test (a, b, c). Erob enters the motion routing trajectory of the RFID positioning area from any three points: left side, bottom side, and right side. a Erob enters the target area’s trajectory from left side (left). Erob enters the routing path of the positioning area from any three points on the left side. b Erob enters the target area’s trajectory from bottom side (middle). Erob enters the routing path of the positioning area from any three points on the middle side. c Erob enters the target area’s trajectory from right side (right). Erob enters the routing path of the positioning area from any three points on the right side
