Define a class to accept a string and convert it into uppercase. Count and display thenumber of vowels in it.Input: roboticsOutput: ROBOTICSNumber of vowels: 3

Here is a Python class that accomplishes this:

class StringManipulator:
    def __init__(self, input_string):
        self.input_string = input_string

    def convert_to_uppercase(self):
        return self.input_string.upper()

    def count_vowels(self):
        vowels = ['a', 'e', 'i', 'o', 'u']
        count = 0
        for char in self.input_string:
            if char.lower() in vowels:
                count += 1
        return count

# Create an instance of the class
manipulator = StringManipulator("robotics")

# Convert to uppercase
uppercase_string = manipulator.convert_to_uppercase()
print("Uppercase string: ", uppercase_string)

# Count vowels
vowel_count = manipulator.count_vowels()
print("Number of vowels: ", vowel_count)

This class, StringManipulator, takes a string as input when an instance is created. It has two methods: convert_to_uppercase and count_vowels. The convert_to_uppercase method returns the input string converted to uppercase. The count_vowels method counts the number of vowels in the input string and returns the count.
