| Abstract: | A vision-based navigation and 4-wheel-drive agricultural robot platform was designed.A controller based on single-chip-microcomputer was designed.Velocities of 4 motors were controlled separately and communication between computer and controller was realized by serial port.Tests showed that the controller can satisfy control requirement of robot’s movement.A algorithm that combines least squares fitting with line scan algorithm is developed to extract navigation path between crop lines.The results showed that the algorithm is in real-time and can be used in circumstance of simulated crop lines. |
