3. FUNCTIONAL PROCEDURES
1. "Door Maker" sends the message to the wheel
2. Wheel sends 'door marker' event to the module
3. On receiving 'door marker' event, module checks its calculated direction to determine if
cart is moving outdoor or indoor.
4. If cart is moving outdoor, the module starts the navigation algorithm processing. It
calculates the real-time position of the cart from the rotations it receives from the
wheel(s) and the direction information it calculates.
5. If position of cart calculated is mapped to be outside the perimeter map it has in its
memory, then the module will send lock command to the wheel after providing warning
using its led and audio.
4. INSATALLATION
1. Mount the Module in the Shopping Cart Handle.
2. When mounting a module to a shopping cart handle, it is typically mounted facing up at
roughly 10deg angle with the horizontal ground plane.
