Create a computer program that can search its environment for a red ball.
Here is an example of a Python program that can search for a red ball in an image using the OpenCV computer vision library:

```python
import cv2
import numpy as np

# Load the image into a variable
image = cv2.imread('image.jpg')

# Convert the image from BGR to HSV color space
hsv = cv2.cvtColor(image, cv2.COLOR_BGR2HSV)

# Define the range of red color in HSV
lower_red = np.array([0, 120, 70])
upper_red = np.array([10, 255, 255])

# Create a mask to only select the red color pixels
mask = cv2.inRange(hsv, lower_red, upper_red)

# Use the mask to select the red color pixels in the original image
result = cv2.bitwise_and(image, image, mask=mask)

# Convert the result image to grayscale
result_gray = cv2.cvtColor(result, cv2.COLOR_BGR2GRAY)

# Detect circles in the greyscale image using the HoughCircles method
circles = cv2.HoughCircles(result_gray, cv2.HOUGH_GRADIENT, 1, 20, param1=50, param2=30, minRadius=0, maxRadius=0)

# Check if any circles were found
if circles is not None:
    # Convert the (x, y) coordinates and radius of the circles to integers
    circles = np.round(circles[0, :]).astype("int")
    
    # Loop over the (x, y) coordinates and radius of the circles
    for (x, y, r) in circles:
        # Draw the circle in the output image
        cv2.circle(image, (x, y), r, (0, 255, 0), 4)
        # Put a text to indicate that red ball is found
        cv2.putText(image, "Red Ball Found", (x - 50, y - 50), cv2.FONT_HERSHEY_SIMPLEX, 0.6, (0, 255, 0), 2)
else:
    # Put a text to indicate that red ball is not found
    cv2.putText(image, "Red Ball Not Found", (50, 50), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 0, 255), 2)

# Display the output image
cv2.imshow('
