Creating a complete smart agriculture monitoring system with robotics harvesting capabilities involves a multitude of components and complexities. However, I can provide you with a basic example of Python code for a simple monitoring system that gathers data from sensors and displays it. As for robotics harvesting, it would require additional hardware components and more complex algorithms, which might not be feasible to cover fully here. But I can guide you on where to start with the monitoring system. 

Let's create a simple Python script for monitoring temperature and humidity using a hypothetical sensor:

```python
import random
import time

# Function to simulate temperature and humidity readings
def read_sensor_data():
    temperature = random.uniform(20, 30)  # Simulate temperature between 20 to 30 degrees Celsius
    humidity = random.uniform(40, 60)     # Simulate humidity between 40% to 60%
    return temperature, humidity

# Function to display sensor data
def display_data(temperature, humidity):
    print("Temperature: {:.2f}°C".format(temperature))
    print("Humidity: {:.2f}%".format(humidity))

# Main function
def main():
    try:
        while True:
            temperature, humidity = read_sensor_data()
            display_data(temperature, humidity)
            time.sleep(1)  # Read data every 1 second
    except KeyboardInterrupt:
        print("Monitoring stopped.")

if __name__ == "__main__":
    main()
