CAB SYSTEM

•The robot signals the central controller via GSM to indicate its state.•Distance between robots destination and current location is also evaluated via Haversine formulae.•The robot then navigates itself to user by constantly evaluating the required heading

DIFFERENCE BETWEEN HEADING AND BEARING

HEADING CALCULATION

Navigation Between Road Corners

• We have achieved navigation between two coordinates.

• To stay between road boundaries we require a nearly straight heading to traverse

• Thence we use various coordinates with each coordinate at every corner to keep robot within boundary.

Python

• We have used python to calculate route coordinates.

• GIKI map was used from openstreetmap.• Pyserial for communication with arduino• Pyroute code containing A* algorithm for

route evaluation
