Usage

0. Prepare the mobile robot and the DGPS (USB Cable, Power, PC)

1. Compile and execute DGPS.c

2. Complie and execute navigation.c

Algorithm

1. The mobile robot achives the autonomous navigation by approaching the targets(waypoints) from start to the goal

2. The robot mainly calculates its position by encoder connected to right and left wheels.

3. If the distance between the robot and the target is less than 0.5m, change target to next waypoint.

4. In order to modify the positioning error caused by wheel slippage, we use DGPS(Differential Global Positioning System).

5. The DGPS's positioning data is shared with MainProgram(navigation.c) by share memory.

6. Hemisphere A101 is used as the DGPS (https://hemispheregnss.com/Products/Products/Position/a101e284a2-smart-antenna-758)
